How to hide soft keyboard on android after clickin

Question

Ok everyone knows that to hide a keyboard you need to implement:

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

But the big deal here is how to hide the keyboard when the user touches or selects any other place that is not an EditText or the softKeyboard?

I tried to use the onTouchEvent() on my parent Activity but that only works if user touches outside any other view and there is no scrollview.

I tried to implement a touch, click, focus listener without any success.

I even tried to implement my own scrollview to intercept touch events but I can only get the coordinates of the event and not the view clicked.

Is there a standard way to do this?? in iPhone it was really easy.

Answer 1

Just Add this code in the class @Overide

public boolean dispatchTouchEvent(MotionEvent ev) {
    View view = getCurrentFocus();
    if (view != null && (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) && view instanceof EditText && !view.getClass().getName().startsWith("android.webkit.")) {
        int scrcoords[] = new int[2];
        view.getLocationOnScreen(scrcoords);
        float x = ev.getRawX() + view.getLeft() - scrcoords[0];
        float y = ev.getRawY() + view.getTop() - scrcoords[1];
        if (x < view.getLeft() || x > view.getRight() || y < view.getTop() || y > view.getBottom())
            ((InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow((this.getWindow().getDecorView().getApplicationWindowToken()), 0);
    }
    return super.dispatchTouchEvent(ev);
}

The following snippet simply hides the keyboard:

public static void hideSoftKeyboard(Activity activity) {
    InputMethodManager inputMethodManager = 
        (InputMethodManager) activity.getSystemService(
            Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow(
        activity.getCurrentFocus().getWindowToken(), 0);
}

You can put this up in a utility class, or if you are defining it within an activity, avoid the activity parameter, or call hideSoftKeyboard(this).

The trickiest part is when to call it. You can write a method that iterates through every View in your activity, and check if it is an instanceof EditText if it is not register a setOnTouchListener to that component and everything will fall in place. In case you are wondering how to do that, it is in fact quite simple. Here is what you do, you write a recursive method like the following, in fact you can use this to do anything, like setup custom typefaces etc... Here is the method

public void setupUI(View view) {

    // Set up touch listener for non-text box views to hide keyboard.
    if (!(view instanceof EditText)) {
        view.setOnTouchListener(new OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                hideSoftKeyboard(MyActivity.this);
                return false;
            }
        });
    }

    //If a layout container, iterate over children and seed recursion.
    if (view instanceof ViewGroup) {
        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            View innerView = ((ViewGroup) view).getChildAt(i);
            setupUI(innerView);
        }
    }
}

That is all, just call this method after you setContentView in your activity. In case you are wondering what parameter you would pass, it is the id of the parent container. Assign an id to your parent container like

<RelativeLayoutPanel android:id="@+id/parent"> ... </RelativeLayout>

and call setupUI(findViewById(R.id.parent)), that is all.

If you want to use this effectively, you may create an extended Activity and put this method in, and make all other activities in your application extend this activity and call its setupUI() in the onCreate() method.

Hope it helps.

If you use more than 1 activity define common id to parent layout like <RelativeLayout android:id="@+id/main_parent"> ... </RelativeLayout>

Then extend a class from Activity and define setupUI(findViewById(R.id.main_parent)) Within its OnResume() and extend this class instead of ``Activityin your program

I liked the approach of calling dispatchTouchEvent made by htafoya, but:

• I didn't understand the timer part (don't know why measuring the downtime should be necessary?)
• I don't like to register/unregister all EditTexts with every view-change (could be quite a lot of viewchanges and edittexts in complex hierarchies)

So, I made this somewhat easier solution:

@Override
public boolean dispatchTouchEvent(final MotionEvent ev) {
    // all touch events close the keyboard before they are processed except EditText instances.
    // if focus is an EditText we need to check, if the touchevent was inside the focus editTexts
    final View currentFocus = getCurrentFocus();
    if (!(currentFocus instanceof EditText) || !isTouchInsideView(ev, currentFocus)) {
        ((InputMethodManager) getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE))
            .hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
    return super.dispatchTouchEvent(ev);
}

/**
 * determine if the given motionevent is inside the given view.
 * 
 * @param ev
 *            the given view
 * @param currentFocus
 *            the motion event.
 * @return if the given motionevent is inside the given view
 */
private boolean isTouchInsideView(final MotionEvent ev, final View currentFocus) {
    final int[] loc = new int[2];
    currentFocus.getLocationOnScreen(loc);
    return ev.getRawX() > loc[0] && ev.getRawY() > loc[1] && ev.getRawX() < (loc[0] + currentFocus.getWidth())
        && ev.getRawY() < (loc[1] + currentFocus.getHeight());
}

There is one disadvantage:

Switching from one EditText to another EditText makes the keyboard hide and reshow - in my case it's desired that way, because it shows that you switched between two input components.

Try to put stateHidden on as your activity windowSoftInputMode value

http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode

For example for your Activity:

this.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

Answer 5

its too simple, just make your recent layout clickable an focusable by this code:

android:id="@+id/loginParentLayout"
android:clickable="true"
android:focusableInTouchMode="true"

and then write a method and an OnClickListner for that layout , so that when the uppermost layout is touched any where it will call a method in which you will write code to dismiss keyboard. following is the code for both; // you have to write this in OnCreate()

 yourLayout.setOnClickListener(new View.OnClickListener(){
                @Override
                public void onClick(View view) {
                    hideKeyboard(view);
                }
            });

method called from listner:-

 public void hideKeyboard(View view) {
     InputMethodManager imm =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }

Answer 6

@Override
    public boolean onTouchEvent(MotionEvent event) {
        InputMethodManager imm = (InputMethodManager)getSystemService(Context.
                INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        return true;
    }
