Android seekbar clipped thumb

I ran into some weird problem..I implemented a seekbar with custom thumb..and when I ran my app on HTC Desire, it all works fine..but, when I ran it on Samsung Galaxy, the thumb becomes clipped!

Here are the screenshots..

            />
        </shape>
    </clip>
</item>

style:

<style name="mySeekBar">
    <item name="android:indeterminateOnly">false</item>
    <item name="android:progressDrawable">@drawable/myprogress</item>
    <item name="android:indeterminateDrawable">@android:drawable/progress_horizontal</item>
    <item name="android:minHeight">10dip</item>
    <item name="android:maxHeight">10dip</item>
    <item name="android:thumb">@drawable/thumb</item>
    <item name="android:thumbOffset">4dp</item>
    <item name="android:focusable">true</item>

seekbar xml:

<SeekBar android:id="@+id/player_seek_horizontal"
        android:layout_gravity="center_vertical" 
        android:max="100" 
        android:layout_marginLeft="50dp" 
        android:layout_width="180dp" 
        android:thumb="@drawable/thumb" 
        android:layout_height="wrap_content" 
        style="@style/mySeekBar" 
        android:background="@drawable/background_transparent_rounded" 
        android:paddingRight="4dp" android:paddingLeft="4dp"/>

Adjust the android:paddingLeft, android:paddingRight and android:thumbOffset properties of your SeekBar to achieve desired results.

Padding right and left should be half of thumb's width.

<SeekBar
    ...
    android:paddingLeft="5dp"  
    android:paddingRight="5dp"
    android:thumbOffset="0px" />

It worked for me.

add following attributes to your parent layout

android:clipChildren="false"
android:clipToPadding="false"
