Continuously increase integer value as the button is pressed

Question

I\'m new to Android so sorry if the question is easy to answer. I have two buttons, a decrease and an increase button, and in the middle of them a TextView which displays a

While the accepted answer is totally correct, it can be simplified a bit.

Basically, we can optimize two things:

• We don't need the OnTouchListener.
• We can instantiate the runnable object just once instead of creating multiple objects.

So this is my version:

// global variables
Handler handler = new Handler();
Runnable runnable;

increaseView.setOnLongClickListener(new View.OnLongClickListener() {

    @Override
    public boolean onLongClick(View v) {

        runnable = new Runnable() {
            @Override
            public void run() {
                if (!increaseView.isPressed()) return;
                increaseValue();
                handler.postDelayed(runnable, DELAY);
            }
        };

        handler.postDelayed(runnable, DELAY);
        return true;

    }

});

Here the runnable object is reused. And when the view is not pressed anymore, it will stop calling itself.

The decrease view or button can be defined in a similar way.
