Example 1 with SharedElementCallback

use of androidx.core.app.SharedElementCallback in project Douya by DreaminginCodeZH.

the class BroadcastFragment method onActivityCreated.

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    mContainerLayout.setOnClickListener(view -> onFinish());
    ViewCompat.setTransitionName(mSharedView, Broadcast.makeTransitionName(mBroadcastId));
    // This magically gives better visual effect when the broadcast is partially visible. Using
    // setEnterSharedElementCallback() disables this hack when no transition is used to start
    // this Activity.
    ActivityCompat.setEnterSharedElementCallback(activity, new SharedElementCallback() {

        @Override
        public void onSharedElementEnd(List<String> sharedElementNames, List<View> sharedElements, List<View> sharedElementSnapshots) {
            mBroadcastCommentList.scrollToPosition(0);
