The button on the Touch Listener does not open when you move your finger. Android

Question

I have RelativeLayout15 buttons, I’m working on a new project and with OnTouchListener, I want my application to do something like this: when a user touches, for example, button 1, Mp1 will start playing until the user lifts his finger or move it to button 2, then start mp2 on button 2, etc.

But here's what happens when the user touches the screen and the elevator works fine, but if the user presses a finger (doesn't lift), if button 1 is pressed, he will still be in the pressed state (action down) until the user lifts his finger. Something like that:

My question is:

, " ", ( )? :

sound1.setOnTouchListener(new OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == android.view.MotionEvent.ACTION_DOWN) {
                    pressed1 = true;
                    mp1 = MediaPlayer.create(MainClass.this, R.raw.item1);
                    mp1.start();
                    sound1.setBackgroundResource(R.drawable.pad_pressed);
                    if (looping == true) {
                        mp1.setLooping(true);
                    } else if (looping == false) {
                        mp1.setLooping(false);
                    }

                } else if (event.getAction() == android.view.MotionEvent.ACTION_UP) {
                    pressed1 = false;
                    mp1.stop();
                    mp1.reset();
                    mp1.release();
                    sound1.setBackgroundResource(R.drawable.pad_normal);
                }
                return true;
            }

:

sound1.setOnTouchListener(new OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == android.view.MotionEvent.ACTION_DOWN) {

                    mp1 = MediaPlayer.create(MainClass.this, R.raw.item1);
                    mp1.start();
