Activity's OnTouchEvent() Is Not Being Called While Clicking On Button

I want to do some B.logic in Activity.onTouchEvent() method. It is working fine for TextView and other non clickable views. However, it is not getting called uponclicking of Button

Solution 1:

I have used dispatchTouchEvent(MotionEvent ev) as required. Here is the solution.

private boolean isInSideClicked = false;
public boolean dispatchTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        View content = findViewById(R.id.textView1);
        int[] contentLocation = new int[2];
        content.getLocationOnScreen(contentLocation);
        Rect rect = new Rect(contentLocation[0], 
                             contentLocation[1], 
                             contentLocation[0] + content.getWidth(), 
                             contentLocation[1] + content.getHeight());
        
        View frame = findViewById(R.id.editText1);
        int[] frameLocation = new int[2];
        frame.getLocationOnScreen(frameLocation);
        Rect framerect = new Rect(frameLocation[0], 
                                  frameLocation[1], 
                                  frameLocation[0] + frame.getWidth(), 
                                  frameLocation[1] + frame.getHeight());
        Log.d(TAG, "rect:  "+rect.bottom+" , "+rect.top+" , "+rect.left+" , "+rect.right);
        Log.d(TAG, "FrameRect:  "+framerect.bottom+" , "+framerect.top+" , "+framerect.left+" , "+framerect.right);
        Log.d(TAG, "x: "+event.getX()+"  y: "+event.getY());
        
        if ((rect.contains((int)event.getX(), (int)event.getY()) || framerect.contains((int)event.getX(), (int)event.getY()) ) ) {
            isInSideClicked = true;
        }
        if (isInSideClicked){
            return super.dispatchTouchEvent(event); 
        } else {
            return true;
        }
    } else if (event.getAction() == MotionEvent.ACTION_UP && isInSideClicked) {
        isInSideClicked = false;
        return super.dispatchTouchEvent(event);
    } else if (event.getAction() == MotionEvent.ACTION_MOVE && isInSideClicked) {
        return super.dispatchTouchEvent(event);
    } else {
        isInSideClicked = false;
        return true; 
    }
}

Below is the hierarchy on how the touch event is processed by OS level.

Activity.dispatchTouchEvent()
ViewGroup.dispatchTouchEvent()
View.dispatchTouchEvent()
View.onTouchEvent()
ViewGroup.onTouchEvent()
Activity.onTouchEvent()

With this I have restricted the touch events of the views which are not in required layouts/views.

Solution 2:

Where you have registering the touchListener for the button. You have only implemented the clickListener for the button. To invoke the onTouchEvent() for button,you have to Register the button as: button.setOnTouchListener(this);

Solution 3:

 Please add below given 2 line in your xml hope it will help you its working fine for me.

    **android:focusable="false"
    android:focusableInTouchMode="false"**


     <Button
            android:id="@+id/button2"
            android:layout_width="80dp"
            android:layout_height="40dp"
            android:layout_alignParentRight="true"
            android:layout_below="@+id/button1"
            android:layout_marginTop="3dp"
            android:background="#FFFFFF"
            android:focusable="false"
            android:focusableInTouchMode="false"
            android:text="Delete"
            android:textColor="#0099CC" />

Solution 4:

Please add below code in your onCreate method.

in this you can get down, move or up event of Button.

Write your logic when Button up event call.

findViewById(R.id.btn).setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {

            switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                Toast.makeText(Main.this,
                        "Oh shit!! click down performed... :(",
                        Toast.LENGTH_LONG).show();
                break;
            case MotionEvent.ACTION_MOVE:
                break;
            case MotionEvent.ACTION_UP:
                Toast.makeText(Main.this,
                        "Oh shit!! click up performed... :(",
                        Toast.LENGTH_LONG).show();
                break;
            default:
                break;
            }
            return true;
        }
    });

Solution 5:

I had the same problem. It is very easy to solve, without removing your:

@Override
public boolean onTouchEvent(MotionEvent event) {
    Log.d(TAG, "ssssssssssssssssssssssss:touch");
    return super.onTouchEvent(event);
};

add to the button:

button.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        //YOUR CODE HERE
        if(v==button){
           //Your button has been pressed
        }
        else {  
          //Other View element has been pressed
             }
    }
}
