ActivityOptions.makeSceneTransitionAnimation doesn't seem to exist

Question

Android L introduced a new animations feature: animating between similar Views in different activities. It\'s documented here.

I\'ve tried to use ActivityOpti

Answer 1

We can got it working with theme config for v21. Put these items into res/values-v21/styles.xml

 <item name="android:windowContentTransitions">true</item>
 <item name="android:windowAllowEnterTransitionOverlap">true</item>
 <item name="android:windowAllowReturnTransitionOverlap">true</item>

Answer 2

Okay, I got it working.

It seems like setting the value in styles.xml is completely ignored for now.

You'll need to do this in each Activity's onCreate till that's fixed

getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS);
Transition transition = // load transition here.
getWindow().setSharedElementEnterTransition(transition);
getWindow().setSharedElementExitTransition(transition);

As per the same bug ViewAnimationUtils has, you'll see errors in Android Studio, it'll compile and run fine though.

Answer 3

Here is something work with 5.0 sdk got after 10/17/14.

But not sure what is the expected behavior if enable window content transitions and called setEnterTransition/setExitTransition in both mainActivity and secondActivity. If they are different (e.g one choose Explode and other choose Slide), which one would be applied?

public class MainActivity extends Activity {

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

        /*
        To enable window content transitions in your code instead, call the Window.requestFeature() method:
         */
        getWindow().requestFeature(android.view.Window.FEATURE_CONTENT_TRANSITIONS);
        Transition ts = new Explode();  //Slide(); //Explode();

        ts.setStartDelay(2000);
        ts.setDuration(5000);

        /*
        If you have set an enter transition for the second activity,
        the transition is also activated when the activity starts.
         */

        getWindow().setEnterTransition(ts);
        getWindow().setExitTransition(ts);


        setContentView(R.layout.activity_main_view);
        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                    .add(R.id.container, mainViewFragment.newInstance())
                    .commit();
        }
    }

    public void launchSecondActivity() {

            /*
            If you enable transitions and set an exit transition for an activity,
            the transition is activated when you launch another activity as follows:
             */

            Intent listIntent = new Intent(this, secondActivity.class);
            startActivity(intent, ActivityOptions.makeSceneTransitionAnimation(this).toBundle());

        }

}

//===

public class secondActivity extends Activity {

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

        ///
        getWindow().requestFeature(android.view.Window.FEATURE_CONTENT_TRANSITIONS);
        Transition ts = new Slide();  //Slide(); //Explode();

        ts.setDuration(3000);

        getWindow().setEnterTransition(ts);
        getWindow().setExitTransition(ts);

        ///

        setContentView(R.layout.activity_scene_transition);
        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                    .add(R.id.container, new PlaceholderFragment())
                    .commit();
        }
    }
