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

You can achieve this by doing the following steps:

1. Make the parent view(content view of your activity) clickable and focusable by adding the following attributes

       android:clickable="true" 
       android:focusableInTouchMode="true" 
   

2. Implement a hideKeyboard() method

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

3. Lastly, set the onFocusChangeListener of your edittext.

       edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
           @Override
           public void onFocusChange(View v, boolean hasFocus) {
               if (!hasFocus) {
                   hideKeyboard(v);
               }
           }
       });
   

As pointed out in one of the comments below, this might not work if the parent view is a ScrollView. For such case, the clickable and focusableInTouchMode may be added on the view directly under the ScrollView.

Answer 2

Override public boolean dispatchTouchEvent(MotionEvent event) in any Activity (or extend class of Activity)

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    View view = getCurrentFocus();
    boolean ret = super.dispatchTouchEvent(event);

    if (view instanceof EditText) {
        View w = getCurrentFocus();
        int scrcoords[] = new int[2];
        w.getLocationOnScreen(scrcoords);
        float x = event.getRawX() + w.getLeft() - scrcoords[0];
        float y = event.getRawY() + w.getTop() - scrcoords[1];

        if (event.getAction() == MotionEvent.ACTION_UP 
 && (x < w.getLeft() || x >= w.getRight() 
 || y < w.getTop() || y > w.getBottom()) ) { 
            InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getWindow().getCurrentFocus().getWindowToken(), 0);
        }
    }
 return ret;
}

And that's all you need to do

Answer 3

I modified the solution of Andre Luis IM I achieved this one:

I created a utility method to hide the soft keyboard the same way Andre Luiz IM did:

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

But instead of register an OnTouchListener for every view, that give a poor performance, I registered the OnTouchListener for just the root view. Since the event bubbles until it's consumed (EditText is one of the views that consumes it by default), if it arrives to the root view, it's because it wasn't consumed, so I close the soft keyboard.

findViewById(android.R.id.content).setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        Utils.hideSoftKeyboard(activity);
        return false;
    }
});

Well I manage to somewhat solve the problem, I overrode the dispatchTouchEvent on my activity, there I am using the following to hide the keyboard.

 /**
 * Called to process touch screen events. 
 */
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {

    switch (ev.getAction()){
        case MotionEvent.ACTION_DOWN:
            touchDownTime = SystemClock.elapsedRealtime();
            break;

        case MotionEvent.ACTION_UP:
            //to avoid drag events
            if (SystemClock.elapsedRealtime() - touchDownTime <= 150){  

                EditText[] textFields = this.getFields();
                if(textFields != null && textFields.length > 0){

                    boolean clickIsOutsideEditTexts = true;

                    for(EditText field : textFields){
                        if(isPointInsideView(ev.getRawX(), ev.getRawY(), field)){
                            clickIsOutsideEditTexts = false;
                            break;
                        }
                    }

                    if(clickIsOutsideEditTexts){
                        this.hideSoftKeyboard();
                    }               
                } else {
                    this.hideSoftKeyboard();
                }
            }
            break;
    }

    return super.dispatchTouchEvent(ev);
}

EDIT: The getFields() method is just a method that returns an array with the textfields in the view. To avoid creating this array on every touch, I created an static array called sFields, which is returned at the getFields() method. This array is initialized on the onStart() methods such as:

sFields = new EditText[] {mUserField, mPasswordField};

---

It is not perfect, The drag event time is only based on heuristics so sometimes it doesnt hide when performing long clics, and I also finished by creating a method to get all the editTexts per view; else the keyboard would hide and show when clicking other EditText.

Still, cleaner and shorter solutions are welcome

You may easily override the onKey() event in activity and fragments to hide the keyboard.

@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {

    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        if (keyCode == event.KEYCODE_ENTER) {

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

            return true;
        }
    }
    return false;
}

Answer 6

I'm aware that this thread is quite old, the correct answer seems valid and there are a lot of working solutions out there, but I think the approach stated bellow might have an additional benefit regarding efficiency and elegance.

I need this behavior for all of my activities, so I created a class CustomActivity inheriting from the class Activity and "hooked" the dispatchTouchEvent function. There are mainly two conditions to take care of:

1. If focus is unchanged and someone is tapping outside of the current input field, then dismiss the IME
2. If focus has changed and the next focused element isn't an instance of any kind of an input field, then dismiss the IME

This is my result:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    if(ev.getAction() == MotionEvent.ACTION_UP) {
        final View view = getCurrentFocus();

        if(view != null) {
            final boolean consumed = super.dispatchTouchEvent(ev);

            final View viewTmp = getCurrentFocus();
            final View viewNew = viewTmp != null ? viewTmp : view;

            if(viewNew.equals(view)) {
                final Rect rect = new Rect();
                final int[] coordinates = new int[2];

                view.getLocationOnScreen(coordinates);

                rect.set(coordinates[0], coordinates[1], coordinates[0] + view.getWidth(), coordinates[1] + view.getHeight());

                final int x = (int) ev.getX();
                final int y = (int) ev.getY();

                if(rect.contains(x, y)) {
                    return consumed;
                }
            }
            else if(viewNew instanceof EditText || viewNew instanceof CustomEditText) {
                return consumed;
            }

            final InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

            inputMethodManager.hideSoftInputFromWindow(viewNew.getWindowToken(), 0);

            viewNew.clearFocus();

            return consumed;
        }
    }       

    return super.dispatchTouchEvent(ev);
}

Side note: Additionally I assign these attributes to the root view making it possible to clear focus on every input field and preventing input fields gaining focus on activity startup (making the content view the "focus catcher"):

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    final View view = findViewById(R.id.content);

    view.setFocusable(true);
    view.setFocusableInTouchMode(true);
}
