OnTouchListener - ActionMove (android) is giving different positions at one touch point

I'm trying to make moveable text in my FrameLayout. In TextView I've set OnTouchListener which you can see below. The problem is, that when I'm touching textview (without finger move), OnTouchListener is giving different positions, and my TextView is jumping between different positions.. I've put also LogCat result, which is connected with that situation. Thank you for any help.

onTouchListener = new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            Log.w("KKK", "ONTOUCH EVENT: "+motionEvent.getAction());
            switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
                case MotionEvent.ACTION_DOWN:
                    ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
                    lastTouchX = motionEvent.getX();
                    lastTouchY = motionEvent.getY();
                    Log.w("KKK", "ACTION DOWN X: " + lastTouchX + " Y: " + lastTouchY);
                    break;
                case MotionEvent.ACTION_MOVE:
                    Log.w("KKK", "ACTION MOVE BEFORE X: " + lastTouchX + " Y: " + lastTouchY);
                    float beforeX = lastTouchX, beforeY = lastTouchY;
                    lastTouchX = motionEvent.getX();
                    lastTouchY = motionEvent.getY();
                    Log.w("KKK", "ACTION MOVE AFTER X: " + lastTouchX + " Y: " + lastTouchY);
                    Log.w("KKK", "ACTION MOVE DELTA X: " + (beforeX - lastTouchX) + " Y: " + (beforeY - lastTouchY));
                    float delX = lastTouchX - beforeX;
                    float delY = lastTouchY - beforeY;
                    ViewGroup.MarginLayoutParams lp1 =  (ViewGroup.MarginLayoutParams) view.getLayoutParams();
                    lp1.setMargins(lp1.leftMargin+(int)delX, lp1.topMargin+(int)delY, lp1.rightMargin, lp1.bottomMargin);
                    view.setLayoutParams(lp1);
                    break;
            }
            return true;
        };
    };

Solution

  • Solution:

    I've changed 

    motionEvent.getX();

    to

    motionEvent.getRawX();

    Similar with Y-coordinates methods,

    and it works great.
