I implemented an image transition between two activities using the new shared elements from lollipop. It's working but I get a weird white blinking on the entire screen during the transition and I can't find how to get rid of it. Here is an example:
Here is how the second activity is launched
public static void launch(
@NonNull Activity activity, @NonNull View transitionView, Game game) {
ActivityOptionsCompat options =
ActivityOptionsCompat.makeSceneTransitionAnimation(
activity, transitionView, game.gameFullId);
Intent intent = new Intent(activity, ListImportationLoginActivity.class);
intent.putExtra(INTENT_EXTRA_GAME, retailer);
ActivityCompat.startActivity(activity, intent, options.toBundle());
}
Then in onCreate:
ViewCompat.setTransitionName(mLogoView, mGame.gameFullId);
And the theme file:
<resources>
<style name="Theme.MyApp.NoActionBar" parent="Theme.MyApp.NoActionBar.Base">
<item name="android:windowContentTransitions">true</item>
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>
<item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
<item name="android:windowSharedElementExitTransition">@android:transition/move</item>
</style>
</resources>
Thanks for your help
On the exiting activity, call
getWindow().setExitTransition(null);
On the entering activity, call
getWindow().setEnterTransition(null);
It will prevent the fade out of the exiting activity and the fade in of the entering activity, which removes the apparent blinking effect.
