<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@android:id/background">
<shape>
<corners android:radius="5dip" />
<gradient
android:startColor="#ff9d9e9d"
android:centerColor="#ff5a5d5a"
android:centerY="0.75"
android:endColor="#ff747674"

<item android:id="@android:id/background"
android:drawable="@drawable/progress_bg" />

android:drawable="@drawable/progress_bg" />
<item android:id="@android:id/secondaryProgress">
<clip android:drawable="@drawable/second_progress" />
