Step 2. Create animation in XML

<?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false" > <item android:drawable="@drawable/monster0" android:duration="250"/> <item android:drawable="@drawable/monster1" android:duration="250"/> <item android:drawable="@drawable/monster2" android:duration="250"/> <item android:drawable="@drawable/monster3" android:duration="250"/> <item android:drawable="@drawable/monster4" android:duration="250"/> <item android:drawable="@drawable/monster5" android:duration="250"/> <item android:drawable="@drawable/monster6" android:duration="250"/> <item android:drawable="@drawable/monster7" android:duration="250"/> <item android:drawable="@drawable/monster8" android:duration="250"/> <item android:drawable="@drawable/monster9" android:duration="250"/> </animation-list>
