title: SeekBar in android
body: <p>I am trying to customize the seek bar by making it vertical and changing the progress and thumb image. But when I try to set the progress image, it shows a very thin image rather than a complete image. How this can be achieved?</p>
  
  <p>XML File</p>
  
  <pre><code> &lt;com.example.verticalseekbar.VerticalSeekbar
      android:id="@+id/seekbar"
      android:layout_width="300dip"
      android:layout_height="116dp"
      android:layout_marginRight="10dip"
      android:padding="8dp"
      android:progressDrawable="@drawable/panel"
      android:thumb="@drawable/thumb1" &gt;
  &lt;/com.example.verticalseekbar.VerticalSeekbar&gt;
  </code></pre>
