title: Seekbar thumb image gets cut off
body: <p>I have setup a seekbar with a custom thumb image. The initial image is set by XML file and shows fine no cut off. When I make change to image the image gets cut off on the bottom. The seekbar XML is loaded into a framelayout. Seekbar works fine but movement runs past view. So the when I run to max the top gets cut off and when I rum to minimum the bottom gets cut. Both  images are the same size.</p>
  
  <p>Here is the initial XML </p>
  
  <pre><code>       &lt;SeekBar
      android:id="@+id/seekBarr"
      android:layout_width="300dp"
      android:layout_height="70dp"
      android:layout_marginLeft="-100dp"
      android:layout_marginTop="230dp"
      android:progressDrawable="@drawable/mastersliderback"
      android:rotation="270"
      android:thumb="@drawable/imgsliderred70" /&gt;
  </code></pre>
  
  <p>here is the code that loads new image. </p>
  
  <pre><code>    Drawable thumb1 = getResources().getDrawable(       R.drawable.imgsliderred70_rate);
      SliderRed.setThumb(thumb1);
  </code></pre>
