我正在尝试使用前Lollipop设备(4.x)上的共享元素进行活动转换.可能吗？到目前为止,我正在尝试这个:

public class RewardDetail extends ActionBarActivity {
    @Override
    public void onCreate(final Bundle savedInstanceState) {
        ...

        ViewCompat.setTransitionName(imageView, TRANSITION_NAME);
    }

    ...

    public static void launch(ActionBarActivity activity, View transitionView, WelcomeReward detailData) {
        ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(activity, transitionView, TRANSITION_NAME);
        Intent intent = new Intent(activity, RewardDetail.class);
        intent.putExtra(PARAM_DATA, detailData);
        ActivityCompat.startActivity(activity, intent, options.toBundle());
    }
}

叫做:

@Override
public void onClick(final View v) {
    int position = recyclerView.getChildPosition(v);
    WelcomeReward welcomeReward = data.get(position);
    RewardDetail.launch(WelcomeRewardActivity.this, v.findViewById(R.id.reward_view), welcomeReward);
}

但它导致"常规"转换(没有共享元素).有任何想法吗？

是否有一个图书馆已经为棒棒糖前实现了这个？
