The following piece of code is designed to show a toast with each Action Up event. But, it shows nothing. Find and explain the problem, then fix it. (7m) 1view.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch (View v, Motion Event event) { boolean flag=true; int action event.getActionMasked(); if(action == Motion Event.ACTION_DOWN) { //some code goes here flag- ! flag; 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16}); } } if(action == MotionEvent.ACTION_UP){ Toast.makeText (self, "Action UP", Toast.LENGTH_SHORT).show(); flag- ! flag; } return flag;
