How to set button click effect in Android?

Question

In Android, when I set background image to Button, I can not see any effect on button.

I need some effect on button so user can recognize that button is clicked.

Answer 1

Or using only one background image you can achive the click effect by using setOnTouchListener

Two ways

((Button)findViewById(R.id.testBth)).setOnTouchListener(new OnTouchListener() {

      @Override
        public boolean onTouch(View v, MotionEvent event) {
          switch (event.getAction()) {
              case MotionEvent.ACTION_DOWN: {
                  Button view = (Button) v;
                  view.getBackground().setColorFilter(0x77000000, PorterDuff.Mode.SRC_ATOP);
                  v.invalidate();
                  break;
              }
              case MotionEvent.ACTION_UP:
                  // Your action here on button click
              case MotionEvent.ACTION_CANCEL: {
                  Button view = (Button) v;
                  view.getBackground().clearColorFilter();
                  view.invalidate();
                  break;
              }
          }
          return true;
        }
});

And if you don't want to use setOnTouchLister, the another way of achieving this is

    myButton.getBackground().setColorFilter(.setColorFilter(0xF00, Mode.MULTIPLY);

    StateListDrawable listDrawable = new StateListDrawable();
    listDrawable.addState(new int[] {android.R.attr.state_pressed}, drawablePressed);
    listDrawable.addState(new int[] {android.R.attr.defaultValue}, myButton);

    myButton.setBackgroundDrawable(listDrawable);
