The event when user releases his finger is MotionEvent.ACTION_UP. I'm not aware if there are any guidelines which prohibit using View.OnTouchListener instead of onClick(), most probably it depends of situation.

Here's a sample code:

imageButton.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP){

            // Do what you want
            return true;
        }
        return false;
    }
});

OnClick is triggered when the user releases the button   But if you still want to use the TouchListener you need to add it in code   It s just   myView setOnTouchListener new View OnTouchListener            Implementation

for use sample touch listener just you need this code   Override public boolean onTouch View view  MotionEvent motionEvent         ClipData data   ClipData newPlainText              View DragShadowBuilder shadowBuilder   new View DragShadowBuilder view       view startDrag data  shadowBuilder  null  0        return true

Presumably  if one wants to use an OnTouchListener rather than an OnClickListener  then the extra functionality of the OnTouchListener is needed  This is a supplemental answer to show more detail of how an OnTouchListener can be used   Define the listener  Put this somewhere in your activity or fragment   private View OnTouchListener handleTouch   new View OnTouchListener           Override     public boolean onTouch View v  MotionEvent event             int x    int  event getX            int y    int  event getY             switch  event getAction                  case MotionEvent ACTION DOWN                  Log i  TAG    touched down                    break              case MotionEvent ACTION MOVE                  Log i  TAG    moving       x          y                         break              case MotionEvent ACTION UP                  Log i  TAG    touched up                    break                     return true             Set the listener  Set the listener in onCreate  for an Activity  or onCreateView  for a Fragment    myView setOnTouchListener handleTouch     Notes   getX and getY give you the coordinates relative to the view  that is  the top left corner of the view   They will be negative when moving above or to the left of your view  Use getRawX and getRawY if you want the absolute screen coordinates  You can use the x and y values to determine things like swipe direction
