This is another form for creation of Custom SeekBar

<SeekBar                    
    android:id="@+id/frequency_slider"
    android:layout_marginLeft="15px"
    android:layout_width="200px"
    android:layout_height="wrap_content" 
    android:max="9"
    android:thumbOffset="0px"
    android:progress="0"                 
    android:progressDrawable="@drawable/progress"
    android:thumb="@drawable/thumb"/>

progress.xml

<?xml version="1.0" encoding="utf-8"?>
  <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background" 
       android:drawable="@drawable/slider" />

    <item android:id="@android:id/progress">
 <clip android:drawable="@drawable/colorbar" />
</item>
</layer-list>

thumb.xml

<?xml version="1.0" encoding="utf-8"?>    
  <selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/seek_thumb" />
</selector>
