Question

I am working on an application where I want to hide the button, or, say, make the button invisible when I touch the screen and again make the button visible when I again touch the screen.

How I can make it?

Answer 1

Implement an onTouchListener

 // Catch touch events here
@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        System.out.println("Touch Down X:" + event.getX() + " Y:" + event.getY());
    } 
    if (event.getAction() == MotionEvent.ACTION_UP) {
        System.out.println("Touch Up X:" + event.getX() + " Y:" + event.getY());
    }
    return super.onTouchEvent(event);
}

Then in this you’ll want to reference the button and set it’s visibility:

  button1.setVisibility(View.VISIBLE); or View.INVISIBLE
