ViewFlipper Animation

ViewFlipper is a subclass of android.widget.ViewAnimator, so we can apply Animation on ViewFlipper also. Here is a example; the ViwFlipper change in shifting from one view to another view slowly.

create a folder /res/anim, create two xml file to define the flip-in and flip-out animation.
/res/anim/flipin.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
 android:interpolator="@android:anim/decelerate_interpolator">
<translate
 android:fromXDelta="-100%"
 android:toXDelta="0%"
 android:duration="500" />
</set>

/res/anim/flipout.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
 android:interpolator="@android:anim/decelerate_interpolator">
<translate
 android:fromXDelta="0%"
 android:toXDelta="100%"
 android:duration="500" />
</set>

main.xml (It's sam as that in the exercise "ViewFlipper")

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView 
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
