The second type: XML file format:

1. Create the folder Anim under the Res path. To create an XML file in Anim

Such as:

<?xml version= "1.0" encoding= "Utf-8"? ><set xmlns:android= "Http://schemas.android.com/apk/res/android"     >    <translate        android:duration= "        android:fromxdelta" = "0"         Android:fromydelta= "0"        android:toxdelta= "100%"        android:toydelta= "0" >    </translate>    <alpha        android:duration= "$"        Android:fromalpha = "0"        android:toalpha= "1" >    </alpha></set>

2. Write the following code where you want the animation:

Overridependingtransition (r.anim.next_in, R.anim.next_out)
