How to get a continuous Touch Event?

android events touch continuous
daliz picture daliz · Mar 29, 2010 · Viewed 31k times · Source

My class extends View and I need to get continuous touch events on it.

If I use:

public boolean onTouchEvent(MotionEvent me) {

    if(me.getAction()==MotionEvent.ACTION_DOWN) {
        myAction();
    }
    return true;
}

... the touch event is captured once.

What if I need to get continuous touches without moving the finger? Please, tell me I don't need to use threads or timers. My app is already too much heavy.

Thanks.

Use if(me.getAction() == MotionEvent.ACTION_MOVE). It's impossible to keep a finger 100% completely still on the screen so Action_Move will get called every time the finger moves, even if it's only a pixel or two.

You could also listen for me.getAction() == MotionEvent.ACTION_UP - until that happens, the user must still have their finger on the screen.
