Drag a view on touch and back to origin position on touch release


I want to touch drag a view all around the screen and on touch release I want to bring the view back to its origin position.

Here's my code:

private float xCoOrdinate, yCoOrdinate;
private float top2AxOriginXCoordinate, top2AxOriginYCoordinate;

private void initControls(View view) {
    top2AX = view.findViewById(R.id.top2AX);
    top2AxOriginXCoordinate = top2AX.getX();
    top2AxOriginYCoordinate = top2AX.getY();
    addDragListener();
}

private void addDragListener() {
     myView.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View view, MotionEvent event) {
                switch (event.getActionMasked()) {
                    case MotionEvent.ACTION_DOWN:
                        xCoOrdinate = view.getX() - event.getRawX();
                        yCoOrdinate = view.getY() - event.getRawY();
                        break;
                    case MotionEvent.ACTION_MOVE:
                        view.animate().x(event.getRawX() + xCoOrdinate).y(event.getRawY() + yCoOrdinate).setDuration(0).start();
                        break;
                    case MotionEvent.ACTION_UP:
                        view.animate().x(top2AxOriginXCoordinate).y(top2AxOriginYCoordinate).setDuration(500).start();
                        break;
                    default:
                        return false;
                }
                return true;
            }
        });
}

The touch and drag is working perfectly, but when I release touch its not coming back to its origin position. It goes to the top left of the screen with a slight left margin. What am I doing wrong here?


Solution

  •  top2AxOriginXCoordinate = top2AX.getX();
    top2AxOriginYCoordinate = top2AX.getY();
    

    may be this two variables are 0.0 , if it's so then told me I'll help you
