48.5 Custom Transitions and TransitionSets in XML

While custom transitions can be implemented in code, it is often easier to do so via XML transition files using the <fade> and <changeBounds> tags together with some additional options. The following XML includes a single changeBounds transition:

<?xml version="1.0" encoding="utf-8"?>

<changeBounds/>

As with the code based approach to working with transitions, each transition entry in a resource file may be customized. The XML below, for example, configures a duration for a change bounds transition:

<changeBounds android:duration="5000" >

Multiple transitions may be bundled together using the <transitionSet> element:

<?xml version="1.0" encoding="utf-8"?>

<transitionSet

  xmlns:android="http://schemas.android.com/apk/res/android" >

 

  <fade
