  • You do this at the theme level ( res/values/styles.xml):
	<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowAnimationStyle">
            @style/FragmentAnimation</item>
    </style>

    <style name="FragmentAnimation"
        parent="@android:style/Animation.Activity">
    <item name="android:fragmentOpenEnterAnimation">
        @animator/fragment_enter</item>
    <item name="android:fragmentOpenExitAnimation">
        @animator/fragment_exit</item>
    <item name="android:fragmentCloseEnterAnimation">
        @animator/fragment_pop_enter</item>
    <item name="android:fragmentCloseExitAnimation">
        @animator/fragment_pop_exit</item>
    <item name="android:fragmentFadeEnterAnimation">
        @android:animator/fade_in</item>
        <item name="android:fragmentFadeExitAnimation">
            @android:animator/fade_out</item>
    </style>

</resources>
  • Use fragments as you do it usually
  • Note : Adding fragment transitions to the theme will work only for the native implementation(android.app.Fragment). The Support Library cannot look for these attributes in a theme because they did not exist in earlier platform versions.
  • If you wanted to customize both the activity and fragment transitions in the theme, you would do it like this :
<resources>
<style name="AppTheme" parent="android:Theme.Holo.Light">
<item name="android:windowAnimationStyle">
@style/TransitionAnimation</item>
</style>
<style name="TransitionAnimation"
parent="@android:style/Animation.Activity">
<item name="android:activityOpenEnterAnimation">
@anim/activity_open_enter</item>
<item name="android:activityOpenExitAnimation">
@anim/activity_open_exit</item>
<item name="android:activityCloseEnterAnimation">
@anim/activity_close_enter</item>
<item name="android:activityCloseExitAnimation">
@anim/activity_close_exit</item>
<item name="android:fragmentOpenEnterAnimation">
@animator/fragment_enter</item>
<item name="android:fragmentOpenExitAnimation">
@animator/fragment_exit</item>
<item name="android:fragmentCloseEnterAnimation">
@animator/fragment_pop_enter</item>
<item name="android:fragmentCloseExitAnimation">
@animator/fragment_pop_exit</item>
<item name="android:fragmentFadeEnterAnimation">
@android:animator/fade_in</item>
<item name="android:fragmentFadeExitAnimation">
@android:animator/fade_out</item>
</style>
</resources>
