Animation transition between activities using FLAG_ACTIVITY_CLEAR_TOP

CoolMcGrr is right, you want to use overridePendingTransition(int enterAnim, int exitAnim).

To specifically get the standard “back button” transition, I use these as the enterAnim and exitAnim transitions:

push_right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="-100%p" android:toXDelta="0" android:duration="@android:integer/config_shortAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="@android:integer/config_shortAnimTime" />
</set>

push_right_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="0" android:toXDelta="100%p" android:duration="@android:integer/config_shortAnimTime"/>
    <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="@android:integer/config_shortAnimTime" />
</set>
