I have added an image right of the text in an EditText widget, using the following XML:
<EditText
android:id=\"@+id/txtsearch\"
...
android:layout_gravity=\"center_vertical\"
android:background=\"@layout/shape\"
android:hint=\"Enter place,city,state\"
android:drawableRight=\"@drawable/cross\" />
But I want to clear the EditText when the embedded image is clicked. How can I do this?
Actually you don\'t need to extend any class. Let\'s say I have an EditText editComment with a drawableRight
editComment.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_LEFT = 0;
final int DRAWABLE_TOP = 1;
final int DRAWABLE_RIGHT = 2;
final int DRAWABLE_BOTTOM = 3;
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
// your action here
return true;
}
}
return false;
}
});
we getRawX() because we want to get the actual position of touch on screen, not relative to parent.
To get left side click
if(event.getRawX() <= (editComment.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width()))
Very, very good, thanks to everyone who contributed to this discussion. So if you don\'t want to deal with inconvenience of extending the class you can do the following (implemented for the right drawable only)
this.keyword = (AutoCompleteTextView) findViewById(R.id.search);
this.keyword.setOnTouchListener(new RightDrawableOnTouchListener(keyword) {
@Override
public boolean onDrawableTouch(final MotionEvent event) {
return onClickSearch(keyword,event);
}
});
private boolean onClickSearch(final View view, MotionEvent event) {
// do something
event.setAction(MotionEvent.ACTION_CANCEL);
return false;
}
And here\'s bare-bone listener implementation based on @Mark\'s answer
public abstract class RightDrawableOnTouchListener implements OnTouchListener {
Drawable drawable;
private int fuzz = 10;
/**
* @param keyword
*/
public RightDrawableOnTouchListener(TextView view) {
super();
final Drawable[] drawables = view.getCompoundDrawables();
if (drawables != null && drawables.length == 4)
this.drawable = drawables[2];
}
/*
* (non-Javadoc)
*
* @see android.view.View.OnTouchListener#onTouch(android.view.View, android.view.MotionEvent)
*/
@Override
public boolean onTouch(final View v, final MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN && drawable != null) {
final int x = (int) event.getX();
final int y = (int) event.getY();
final Rect bounds = drawable.getBounds();
if (x >= (v.getRight() - bounds.width() - fuzz) && x <= (v.getRight() - v.getPaddingRight() + fuzz)
&& y >= (v.getPaddingTop() - fuzz) && y <= (v.getHeight() - v.getPaddingBottom()) + fuzz) {
return onDrawableTouch(event);
}
}
return false;
}
public abstract boolean onDrawableTouch(final MotionEvent event);
}
Consider the following. It\'s not the most elegant solution but it works, I just tested it.
Create a customized EditText class CustomEditText.java:
import android.content.Context;
import android.graphics.Rect;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.EditText;
public class CustomEditText extends EditText
{
private Drawable dRight;
private Rect rBounds;
public CustomEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CustomEditText(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomEditText(Context context) {
super(context);
}
@Override
public void setCompoundDrawables(Drawable left, Drawable top,
Drawable right, Drawable bottom)
{
if(right !=null)
{
dRight = right;
}
super.setCompoundDrawables(left, top, right, bottom);
}
@Override
public boolean onTouchEvent(MotionEvent event)
{
if(event.getAction() == MotionEvent.ACTION_UP && dRight!=null)
{
rBounds = dRight.getBounds();
final int x = (int)event.getX();
final int y = (int)event.getY();
//System.out.println(\"x:/y: \"+x+\"/\"+y);
//System.out.println(\"bounds: \"+bounds.left+\"/\"+bounds.right+\"/\"+bounds.top+\"/\"+bounds.bottom);
//check to make sure the touch event was within the bounds of the drawable
if(x>=(this.getRight()-rBounds.width()) && x<=(this.getRight()-this.getPaddingRight())
&& y>=this.getPaddingTop() && y<=(this.getHeight()-this.getPaddingBottom()))
{
//System.out.println(\"touch\");
this.setText(\"\");
event.setAction(MotionEvent.ACTION_CANCEL);//use this to prevent the keyboard from coming up
}
}
return super.onTouchEvent(event);
}
@Override
protected void finalize() throws Throwable
{
dRight = null;
rBounds = null;
super.finalize();
}
}
Change your layout XML to this (where com.example is your actual project package name):
<com.example.CustomEditText
android:id=\"@+id/txtsearch\"
…
android:layout_gravity=\"center_vertical\"
android:background=\"@layout/shape\"
android:hint=\"Enter place,city,state\"
android:drawableRight=\"@drawable/cross\"
/>
Finally, add this (or something similar) to your activity:
…
CustomEditText et = (CustomEditText) this.findViewById(R.id.txtsearch);
…
I might be a bit off with the calculation of the touch bounds for the nested drawable but you get the idea.
I hope this helps.
I created a useful abstract class DrawableClickListener which implements OnTouchListener.
In addition to the DrawableClickListener class, I also created 4 additional abstract classes which extend the DrawableClickListener class and handle the clicking of the drawable area for the correct quadrant.
Point to Consider
One thing to consider is that the images are not resized if done this way; thus the images must be scaled correctly before being put into the res/drawable folder(s).
If you define a LinearLayout containing an ImageView and a TextView, it\'s a lot easier to manipulate the size of the image being displayed.

That last contribution\'s use of contains(x,y) won\'t work directly on the result of getBounds() (except, by coincidence, when using \"left\" drawables). The getBounds method only provides the Rect defining points of the drawable item normalized with origin at 0,0 - so, you actually need to do the math of the original post to find out if the click is in the area of the drawable in the context of the containing EditText\'s dimensions, but change it for top, right, left etc. Alternatively you could describe a Rect that has coordinates actually relative to its position in the EditText container and use contains(), although in the end you\'re doing the same math.
Combining them both gives you a pretty complete solution, I only added an instance attribute consumesEvent that lets the API user decide if the click event should be passed on or not by using its result to set ACTION_CANCEL or not.
Also, I can\'t see why the bounds and actionX, actionY values are instance attributes rather than just local on the stack.
Here\'s a cutout from an implementation based on the above that I put together. It fixes an issue that to properly consume the event you need to return false. It adds a \"fuzz\" factor to. In my use case of a Voice control icon in an EditText field, I found it hard to click, so the fuzz increases the effective bounds that are considered clicking the drawable. For me 15 worked well. I only needed drawableRight so I didn\'t plug the math in the others, to save some space, but you see the idea.

Its very simple. Lets say you have a drawable on left side of your EditText \'txtsearch\'. Following will do the trick.
EditText txtsearch = (EditText) findViewById(R.id.txtsearch);
txtsearch.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() <= txtsearch.getTotalPaddingLeft()) {
// your action for drawable click event
return true;
}
}
return false;
}
});
If you want for right drawable change the if statement to:
if(event.getRawX() >= txtsearch.getRight() - txtsearch.getTotalPaddingRight())
Similarly, you can do it for all compound drawables.
txtsearch.getTotalPaddingTop()
txtsearch.getTotalPaddingBottom()
This method call returns all the padding on that side including any drawables. You can use this even for TextView, Button etc.
Click here for reference from android developer site.
I think it is much more easier if we use some tricks :)
Done
Extending on the idea by RyanM I have created a more flexible version, which supports all the drawable types (top, bottom, left, right). While the code below extends TextView, adapting it for an EditText is just a case of swapping \"extends TextView\" with \"extends EditText\". Instantiation the widget from XML is identical as in RyanM\'s example, bar the widget name.
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.TextView;
import com.example.DrawableClickListener.DrawablePosition;
public class ButtonTextView extends TextView {
private Drawable drawableRight;
private Drawable drawableLeft;
private Drawable drawableTop;
private Drawable drawableBottom;
private int actionX, actionY;
private DrawableClickListener clickListener;
public ButtonTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public ButtonTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ButtonTextView(Context context) {
super(context);
}
@Override
public void setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom) {
if (right != null) {
drawableRight = right;
}
if (left != null) {
drawableLeft = left;
}
if (top != null) {
drawableTop = top;
}
if (bottom != null) {
drawableBottom = bottom;
}
super.setCompoundDrawables(left, top, right, bottom);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
actionX = (int) event.getX();
actionY = (int) event.getY();
if (drawableBottom != null && drawableBottom.getBounds().contains(actionX, actionY)) {
clickListener.onClick(DrawablePosition.BOTTOM);
return super.onTouchEvent(event);
}
if (drawableTop != null && drawableTop.getBounds().contains(actionX, actionY)) {
clickListener.onClick(DrawablePosition.TOP);
return super.onTouchEvent(event);
}
if (drawableLeft != null && drawableLeft.getBounds().contains(actionX, actionY)) {
clickListener.onClick(DrawablePosition.LEFT);
return super.onTouchEvent(event);
}
if (drawableRight != null && drawableRight.getBounds().contains(actionX, actionY)) {
clickListener.onClick(DrawablePosition.RIGHT);
return super.onTouchEvent(event);
}
}
return super.onTouchEvent(event);
}
@Override
protected void finalize() throws Throwable {
drawableRight = null;
drawableBottom = null;
drawableLeft = null;
drawableTop = null;
super.finalize();
}
public void setDrawableClickListener(DrawableClickListener listener) {
this.clickListener = listener;
}}
The DrawableClickListener is as simple as this:
public interface DrawableClickListener {
public static enum DrawablePosition { TOP, BOTTOM, LEFT, RIGHT };
public void onClick(DrawablePosition target); }
And then the actual implementation:
class example implements DrawableClickListener {
public void onClick(DrawablePosition target) {
switch (target) {
case LEFT:
doSomethingA();
break;
case RIGHT:
doSomethingB();
break;
case BOTTOM:
doSomethingC();
break;
case TOP:
doSomethingD();
break;
default:
break;
}
}}
p.s.: If you don\'t set the listener, touching the TextView will cause a NullPointerException. You may want to add some more paranoia into the code.
its working for me,
mEditTextSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if(s.length()>0){
mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(android.R.drawable.ic_delete), null);
}else{
mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(R.drawable.abc_ic_search), null);
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
mEditTextSearch.setOnTouchListener(new OnTouchListener() {
@SuppressLint(\"ClickableViewAccessibility\")
@Override
public boolean onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_UP) {
if(mEditTextSearch.getCompoundDrawables()[2]!=null){
if(event.getX() >= (mEditTextSearch.getRight()- mEditTextSearch.getLeft() - mEditTextSearch.getCompoundDrawables()[2].getBounds().width())) {
mEditTextSearch.setText(\"\");
}
}
}
return false;
}
});
I know this is quite old, but I recently had to do something similar... After seeing how difficult this is, I came up with a much simpler solution:
In my case, I needed an EditText that had the ability to clear the text with a button. I wanted it to look like SearchView, but for a number of reasons I didn\'t want to use that class. The example below shows how I accomplished this. Even though it doesn\'t have to do with focus change, the principles are the same and I figured it would be more beneficial to post actual working code than to put together an example that may not work exactly as I intended:
Here is my layout: clearable_edit_text.xml
<merge
xmlns:android=\"http://schemas.android.com/apk/res/android\"
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\">
<EditText
android:id=\"@+id/edit_text_field\"
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\"/>
<!-- NOTE: Visibility cannot be set to \"gone\" or the padding won\'t get set properly in code -->
<ImageButton
android:id=\"@+id/edit_text_clear\"
android:layout_width=\"wrap_content\"
android:layout_height=\"wrap_content\"
android:layout_gravity=\"right|center_vertical\"
android:background=\"@drawable/ic_cancel_x\"
android:visibility=\"invisible\"/>
</merge>
And here is the Class that inflates that layout: ClearableEditText.java
public class ClearableEditText extends FrameLayout {
private boolean mPaddingSet = false;
/**
* Creates a new instance of this class.
* @param context The context used to create the instance
*/
public ClearableEditText (final Context context) {
this(context, null, 0);
}
/**
* Creates a new instance of this class.

To make this answer more in line with the question the following steps should be taken:
and if drawable is on the left, this will help you. (for those work with RTL layout)
editComment.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_LEFT = 0;
final int DRAWABLE_TOP = 1;
final int DRAWABLE_RIGHT = 2;
final int DRAWABLE_BOTTOM = 3;
if(event.getAction() == MotionEvent.ACTION_UP) {
if (event.getRawX() <= (searchbox.getLeft() + searchbox.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) {
// your action here
return true;
}
}
return false;
}
});
Simply copy paste the following code and it does the trick.
editMsg.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_LEFT = 0;
final int DRAWABLE_TOP = 1;
final int DRAWABLE_RIGHT = 2;
final int DRAWABLE_BOTTOM = 3;
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() >= (editMsg.getRight() - editMsg.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
// your action here
Toast.makeText(ChatActivity.this, \"Message Sent\", Toast.LENGTH_SHORT).show();
return true;
}
}
return false;
}
});
Better to have ImageButton on Right of edit text and give negative layout margin to overlap with edit text. Set listener on ImageButton and perform operations.
@Override
public boolean onTouch(View v, MotionEvent event) {
Drawable drawableObj = getResources().getDrawable(R.drawable.search_btn);
int drawableWidth = drawableObj.getIntrinsicWidth();
int x = (int) event.getX();
int y = (int) event.getY();
if (event != null && event.getAction() == MotionEvent.ACTION_UP) {
if (x >= (searchPanel_search.getWidth() - drawableWidth - searchPanel_search.getPaddingRight())
&& x <= (searchPanel_search.getWidth() - searchPanel_search.getPaddingRight())
&& y >= searchPanel_search.getPaddingTop() && y <= (searchPanel_search.getHeight() - searchPanel_search.getPaddingBottom())) {
getSearchData();
}
else {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(searchPanel_search, InputMethodManager.SHOW_FORCED);
}
}
return super.onTouchEvent(event);
}

It is all great but why not to make it really simple?
I have faced with that also not so long ago...and android touchlistiner works great but gives limitation in usage..and I came to another solution and I hope that will help you:
<LinearLayout
android:orientation=\"vertical\"
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\"
android:id=\"@+id/zero_row\">
<LinearLayout
android:orientation=\"horizontal\"
android:layout_width=\"match_parent\"
android:layout_height=\"match_parent\">
<LinearLayout
android:orientation=\"horizontal\"
android:layout_width=\"wrap_content\"
android:layout_height=\"match_parent\">
<ProgressBar
android:id=\"@+id/loadingProgressBar\"
android:layout_gravity=\"center\"
android:layout_width=\"28dp\"
android:layout_height=\"28dp\" />
</LinearLayout>
<LinearLayout
android:orientation=\"horizontal\"
android:layout_width=\"match_parent\"
android:background=\"@drawable/edittext_round_corners\"
android:layout_height=\"match_parent\"
android:layout_marginLeft=\"5dp\">
<ImageView
android:layout_width=\"28dp\"
android:layout_height=\"28dp\"
app:srcCompat=\"@android:drawable/ic_menu_search\"
android:id=\"@+id/imageView2\"
android:layout_weight=\"0.15\"
android:layout_gravity=\"center|right\"
android:onClick=\"OnDatabaseSearchEvent\" />
<EditText
android:minHeight=\"40dp\"
android:layout_marginLeft=\"10dp\"
android:layout_width=\"wrap_content\"
android:layout_height=\"wrap_content\"
android:background=\"@drawable/edittext_round_corners\"
android:inputType=\"textPersonName\"
android:hint=\"Search..\"
android:textColorHint=\"@color/AndroidWhite\"
android:textColor=\"@color/AndroidWhite\"
android:ems=\"10\"
android:id=\"@+id/e_d_search\"
android:textCursorDrawable=\"@color/AndroidWhite\"
android:layout_weight=\"1\" />
<ImageView
android:layout_width=\"28dp\"
android:layout_height=\"28dp\"
app:srcCompat=\"@drawable/ic_oculi_remove2\"
android:id=\"@+id/imageView3\"
android:layout_gravity=\"center|left\"
android:layout_weight=\"0.15\"
android:onClick=\"onSearchEditTextCancel\" />
</LinearLayout>
<!--android:drawableLeft=\"@android:drawable/ic_menu_search\"-->
<!--android:drawableRight=\"@drawable/ic_oculi_remove2\"-->
</LinearLayout>
</LinearLayout>
![\"enter](\"https://i.stack.imgur.com/ar2RJ.jpg\")
Now you can create ImageClick listener or event and do what ever you want with text. This edittext_round_corners.xml file
<item android:state_pressed=\"false\" android:state_focused=\"false\">
<shape>
<gradient
android:centerY=\"0.2\"
android:startColor=\"@color/colorAccent\"
android:centerColor=\"@color/colorAccent\"
android:endColor=\"@color/colorAccent\"
android:angle=\"270\"
/>
<stroke
android:width=\"0.7dp\"
android:color=\"@color/colorAccent\" />
<corners
android:radius=\"5dp\" />
</shape>
</item>
Compound drawables are not supposed to be clickable. It is cleaner to use separate views in a horizontal LinearLayout and use a click handler on them.
<LinearLayout
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\"
android:layout_marginTop=\"15dp\"
android:background=\"@color/white\"
android:layout_marginLeft=\"20dp\"
android:layout_marginStart=\"20dp\"
android:layout_marginRight=\"20dp\"
android:layout_marginEnd=\"20dp\"
android:layout_gravity=\"center_horizontal\"
android:orientation=\"horizontal\"
android:translationZ=\"4dp\">
<ImageView
android:layout_width=\"wrap_content\"
android:layout_height=\"match_parent\"
android:background=\"@color/white\"
android:minWidth=\"40dp\"
android:scaleType=\"center\"
app:srcCompat=\"@drawable/ic_search_map\"/>
<android.support.design.widget.TextInputEditText
android:id=\"@+id/search_edit\"
style=\"@style/EditText.Registration.Map\"
android:layout_width=\"0dp\"
android:layout_weight=\"1\"
android:layout_height=\"wrap_content\"
android:hint=\"@string/hint_location_search\"
android:imeOptions=\"actionSearch\"
android:inputType=\"textPostalAddress\"
android:maxLines=\"1\"
android:minHeight=\"40dp\" />
<ImageView
android:id=\"@+id/location_gps_refresh\"
android:layout_width=\"wrap_content\"
android:layout_height=\"match_parent\"
android:background=\"@color/white\"
android:minWidth=\"40dp\"
android:scaleType=\"center\"
app:srcCompat=\"@drawable/selector_ic_gps\"/>
</LinearLayout>
For anyone who does not want to implement the monstrous click handling. You can achieve the same with a RelativeLayout. With that you even have free handling of the positioning of the drawable.
<RelativeLayout
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\">
<android.support.design.widget.TextInputLayout
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\">
<android.support.design.widget.TextInputEditText
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\"
/>
</android.support.design.widget.TextInputLayout>
<ImageView
android:layout_width=\"wrap_content\"
android:layout_height=\"wrap_content\"
android:layout_alignParentEnd=\"true\"
android:layout_centerInParent=\"true\"
android:src=\"@drawable/ic_undo\"/>
</RelativeLayout>
The ImageView position will be the same as you would use drawableEnd - plus you don\'t need all the touch listener handling. Just a click listener for the ImageView and you are good to go.
This works fro me:) may this help you as well
edit_account_name.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (event.getRawX() >= (edit_account_name.getRight())) {
//clicked
return true;
}
}
return false;
}
});
Follow below code for drawable right,left,up,down click:
edittextview_confirmpassword.setOnTouchListener(new View.OnTouchListener() {
@Override public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_LEFT = 0;
final int DRAWABLE_TOP = 1;
final int DRAWABLE_RIGHT = 2;
final int DRAWABLE_BOTTOM = 3;
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() >= (edittextview_confirmpassword.getRight() - edittextview_confirmpassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
// your action here edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
return true;
}
}else{
edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
}
return false;
}
});
}
Here\'s my simple solution, just place ImageButton over EditText:
<RelativeLayout
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\">
<EditText android:id=\"@+id/editTextName\"
android:layout_width=\"fill_parent\"
android:layout_height=\"wrap_content\"
android:imeOptions=\"actionSearch\"
android:inputType=\"text\"/>
<ImageButton android:id=\"@+id/imageViewSearch\"
android:layout_width=\"wrap_content\"
android:layout_height=\"wrap_content\"
android:src=\"@drawable/ic_action_search\"
android:layout_alignParentRight=\"true\"
android:layout_centerVertical=\"true\"/>
</RelativeLayout>
I would like to suggest a way for drawable left! I tried this code and works.
txtsearch.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent event) {
final int DRAWABLE_LEFT = 0;
int start=txtsearch.getSelectionStart();
int end=txtsearch.getSelectionEnd();
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() <= (txtsearch.getLeft() + txtsearch.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) {
//Do your action here
return true;
}
}
return false;
}
});
}
I implemented @aristo_sh answer in Mono.Droid (Xamarin), since it\'s a delegate anonymous method you can\'t return true or false you have to take take of e.Event.Handled. I am also hiding the keyboard on click
editText.Touch += (sender, e) => {
e.Handled = false;
if (e.Event.Action == MotionEventActions.Up)
{
if (e.Event.RawX >= (bibEditText.Right - (bibEditText.GetCompoundDrawables()[2]).Bounds.Width()))
{
SearchRunner();
InputMethodManager manager = (InputMethodManager)GetSystemService(InputMethodService);
manager.HideSoftInputFromWindow(editText.WindowToken, 0);
e.Handled = true;
}
}
};
Sharing my generalized solution for handling TextView compound drawable click and touch events.
First we need a touch event handler:
/**
* Handles compound drawable touch events.
* Will intercept every event that happened inside (calculated) compound drawable bounds, extended by fuzz.
* @see TextView#getCompoundDrawables()
* @see TextView#setCompoundDrawablesRelativeWithIntrinsicBounds(int, int, int, int)
*/
public abstract class CompoundDrawableTouchListener implements View.OnTouchListener {
private final String LOG_TAG = \"CmpDrawableTouch\";
private final int fuzz;
public static final int LEFT = 0;
public static final int TOP = 1;
public static final int RIGHT = 2;
public static final int BOTTOM = 3;
private static final int[] DRAWABLE_INDEXES = {LEFT, TOP, RIGHT, BOTTOM};
/**
* Default constructor
*/
public CompoundDrawableTouchListener() {
this(0);
}
/**
* Constructor with fuzz
* @param fuzz desired fuzz in px
*/
public CompoundDrawableTouchListener(int fuzz) {
this.fuzz = fuzz;
}
@Override
public boolean onTouch(View view, MotionEvent event) {
if (!(view instanceof TextView)) {
Log.e(LOG_TAG, \"attached view is not instance of TextView\");
return false;
}
TextView textView = (TextView) view;
Drawable[] drawables = textView.getCompoundDrawables();
int x = (int) event.getX();
int y = (int) event.getY();
for (int i : DRAWABLE_INDEXES) {
if (drawables[i] == null) continue;
Rect bounds = getRelativeBounds(i, drawables[i], textView);
Rect fuzzedBounds = addFuzz(bounds);
if (fuzzedBounds.contains(x, y)) {
MotionEvent relativeEvent = MotionEvent.obtain(
event.getDownTime(),
event.getEventTime(),
event.getAction(),
event.getX() - bounds.left,
event.getY() - bounds.top,
event.getMetaState());
return onDrawableTouch(view, i, bounds, relativeEvent);
}
}
return false;
}
/**
* Calculates compound drawable bounds relative to wrapping view
* @param index compound drawable index
* @param drawable the drawable
* @param view wrapping view
* @return {@link Rect} with relative bounds
*/
private Rect getRelativeBounds(int index, @NonNull Drawable drawable, View view) {
Rect drawableBounds = drawable.getBounds();
Rect bounds = new Rect();
switch (index) {
case LEFT:
bounds.offsetTo(view.getPaddingLeft(),
view.getHeight() / 2 - bounds.height() / 2);
break;
case TOP:
bounds.offsetTo(view.getWidth() / 2 - bounds.width() / 2,
view.getPaddingTop());
break;
case RIGHT:
bounds.offsetTo(view.getWidth() - view.getPaddingRight() - bounds.width(),
view.getHeight() / 2 - bounds.height() / 2);
break;
case BOTTOM:
bounds.offsetTo(view.getWidth() / 2 - bounds.width() / 2,
view.getHeight() - view.getPaddingBottom() - bounds.height());
break;
}
return bounds;
}
/**
* Expands {@link Rect} by given value in every direction relative to its center
* @param source given {@link Rect}
* @return result {@link Rect}
*/
private Rect addFuzz(Rect source) {
Rect result = new Rect();
result.left = source.left - fuzz;
result.right = source.right + fuzz;
result.top = source.top - fuzz;
result.bottom = source.bottom + fuzz;
return result;
}
/**
* Compound drawable touch-event handler
* @param v wrapping view
* @param drawableIndex index of compound drawable which recicved the event
* @param drawableBounds {@link Rect} with compound drawable bounds relative to wrapping view.
* Fuzz not included
* @param event event with coordinated relative to wrapping view - i.e. within {@code drawableBounds}.
* If using fuzz, may return negative coordinates.
*/
protected abstract boolean onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event);
}
Now you can process any touch events on any compound drawable of any TextView you like this way:
textView1.setOnTouchListener(new CompoundDrawableTouchListener() {
@Override
protected void onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event) {
switch(v.getId()) {
case R.id.textView1:
switch(drawableIndex) {
case CompoundDrawableTouchListener.RIGHT:
doStuff();
break;
}
break;
}
}
});
Only interested in clicks? Just filter out by MotionEvent action:
/**
* Handles compound drawable click events.
* @see TextView#getCompoundDrawables()
* @see TextView#setCompoundDrawablesRelativeWithIntrinsicBounds(int, int, int, int)
* @see CompoundDrawableTouchListener
*/
public abstract class CompoundDrawableClickListener extends CompoundDrawableTouchListener {
/**
* Default constructor
*/
public CompoundDrawableClickListener() {
super();
}
/**
* Constructor with fuzz
* @param fuzz desired fuzz in px
*/
public CompoundDrawableClickListener(int fuzz) {
super(fuzz);
}
@Override
protected void onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) onDrawableClick(v, drawableIndex);
return true;
}
/**
* Compound drawable touch-event handler
* @param v wrapping view
* @param drawableIndex index of compound drawable which recicved the event
*/
protected abstract void onDrawableClick(View v, int drawableIndex);
}
Again we can easily handle clicks on any compound drawable of any TextView:
textView1.setOnTouchListener(new CompoundDrawableClickListener() {
@Override
protected void onDrawableClick(View v, int drawableIndex) {
switch(v.getId()) {
case R.id.textView1:
switch(drawableIndex) {
case CompoundDrawableTouchListener.RIGHT:
doStuff();
break;
}
break;
}
}
});
Hope you liked it as I did. I will try to keep it updated here and in related gist if anything changes.
I have created a simple custom touch listener class instead of a custom EditText

private void setupDrawable(final EditText editText) {
editText.addTextChangedListener(new TextWatcher() {
