Question

I tried implementing dragging on android in 2 ways:

1. Canvas with on draw.
2. Relative layout with margins changes on touch.

It’s not smooth enough, even on strong devices.

How can I make dragging faster?

Answer 1

The easiest way (and most responsive) is to handle touches in your view, and when you handle a MotionEvent.ACTION_MOVE, simply set your View‘s x and y points from the event’s raw coordinates and call view.invalidate().
