Question

I have created two buttons in a gridview.

I wish to achieve the following aim but no idea which method should be used?

First i touch on the 1st button, toast 1 msg will be shown. By swiping my finger over to the 2nd button without lifting up my finger, toast 2 msg will be shown.

When i lift up my finger from the screen, toast 3 msg will be shown.

gridview.setOnTouchListener(new OnTouchListener(){
@Override

            gridview.requestFocusFromTouch();
            gridview.setSelection(gridview.pointToPosition((int)event.getX(),(int)event.getY()));
            return true;
