Answer 1

• create a Layout
• add Views to your Layout
• set the setOnTouchListener to your Layout

• override the onTouch method with the following:

  public boolean onTouch(View v, MotionEvent event) 
  {
     LinearLayout layout = (LinearLayout)v;
  
      for(int i =0; i< layout.getChildCount(); i++)
      {
  
          View view = layout.getChildAt(i);
          Rect outRect = new Rect(view.getLeft(), view.getTop(), view.getRight(), view.getBottom());
          if(outRect.contains((int)event.getX(), (int)event.getY()))
          {
                 /* Write code here to maintain all three buttons toched state, and if all bottons state are present generate Toast.              
          }
      }
  }
  

So, for the above code to work, do this in onCreate,

onCreate(Bundle..){
b1.setOnTouchListener(this);
b2.setOnTouchListener(this);
b3.setOnTouchListener(this);
}

Then whenever buttons are touched, onTouch() will be overriden, now write your logic to maintain the touch, and remember to clear the state within some time so that user can not proceed on just touching 3 button if 1st and 2nd button states are already present.

After that if all buttons states are available (that means user slided in such a way that all buttons were touched) so you can generate toast.

Feel free to ask if you have any doubt in suggested approach
