title: How to limit the bound of Scrolling While using onScroll method?
body: <p>I am trying to achieve scrolling of layout by overriding onScroll method of  Gesture Listener </p>
  
  <pre><code>    @Override
          public boolean onScroll(MotionEvent e1, MotionEvent e2,
                  float distanceX, float distanceY) {
              Log.d("Scroll"," X " + this.get +" Y " + this.getScrollY()  );
  
                              // this- Relative Layout
              this.scrollBy((int)distanceX,(int)distanceY);
  
               invalidate();
                  return false;
          }
  </code></pre>
  
  <p>With the above code I am able to scroll the layout but my layout's background is moving out of bound i.e. screen ? How will I limit it ? 
  I tried various thing by getScrolly() , getLeft() but i am not getting any link by which I can go ahead ? please help me ...</p>
