Question

I have class that extends View.

private class Draw2D extends View{
             public Draw2D(Context context) {
        super(context);
              }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        x = event.getX();
        y = event.getY();
        switch(event.getAction()){
        case MotionEvent.ACTION_MOVE:{

            break;
        }

        }
        return super.onTouchEvent(event);
    }


    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        Paint paint = new Paint();
        paint.setStyle(Paint.Style.FILL);
        paint.setColor(Color.WHITE);
        ShapeDrawable rectangle = 
        new ShapeDrawable(new RectShape());
        rectangle.getPaint().setColor(Color.GRAY);
        rectangle.getPaint().setStyle(Paint.Style.STROKE);
        rectangle.getPaint().setStrokeWidth(3);
        rectangle.setBounds(50, 30, 200, 150);
        rectangle.draw(canvas);
    }
}
