Modify from last exercise.
Create /res/anim/rotate.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator">
<rotate
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="1000"
android:startOffset="0"
android:repeatCount="1"
android:repeatMode="reverse" />
</set>
Modify activity_main.xml to add more view to animate.
