How many times I moved my finger not the change of coordinates – Miaoulis Nikos May 24 '16 at 08:33

change of co ordinates means you have moved your finger. not with a major stroke but just a little bit. If you don't move your finger co-ordinates will not be changed.!! – Janki Gadhiya May 24 '16 at 08:36

Action Down Action Move from Point A to Point B this is 1 move not 55 as my code says :) – Miaoulis Nikos May 24 '16 at 08:43

1move can be of (0,1) to (0,2) and (0,0) to (100,100). Its depends on CPU how many times ACTION.MOVE gets called. **Its not that 1 co-ordinate difference is one move**. Read this :https://developer.android.com/reference/android/view/MotionEvent.html – Janki Gadhiya May 24 '16 at 08:47

You have to check for MotionEvent.ACTION_DOWN and then MotionEvent.ACTION_MOVE so you need to make some sort of state machine. If you just check for ACTION_DOWN you will also count clicks.
