Question

I have an activity that appears as a dialog using the following custom theme:

<style name="ThemeDialogNoAnimation">
    <item name="android:windowAnimationStyle">@null</item>
    <item name="android:windowEnterAnimation">@null</item>
    <item name="android:windowExitAnimation">@null</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:backgroundDimEnabled">true</item>
</style>

Notice I have no animations set, yet when the activity exists is still slides to the right. How do I stop it from animating?

Answer 1

The animations you’re seeing most likely come from the system but they’re easy to override.

If you want no transition when the activity starts:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    overridePendingTransition(0, 0);
}

If you want no transitions when the activity finishes:

@Override
public void finish() {
    super.finish();

    overridePendingTransition(0, 0);
}

Passing in 0 when overriding transitions signals to the system to use no transitions. In place of 0 you could also add in a custom transition of your own by passing in the resource identifier to an animation resource.
