Is there a way to share a same LayoutManager between multiple nested RecyclerViews

Question

I'm developing an application that showing a game list, inside every game's itemView, i also have a video list to be showing. preview and structure are following.

I deploy a RecyclerView as the window root view, and then for the videos, i used grid-style RecyclerView to display, so here we got a nested RecyclerView structure.

But there is trouble because the number of videos is inconsistent between games, i don't want the RecyclerView of video list able to being scroll, so the best way is make the View's height stretch dynamically depends on how much rows it have. I heard a disappointing conclusion said there is no a way to accomplish this from internet. Is that really? any alternative can doing this?

So far about this question, i haven't idea to solve it, so i change the RecyclerView's height manually as a temporary solution.

videoGridRecyclerView.getLayoutParams().height = rowCount * 242;

Given that video items are completely same structure, it would be nice if those RecyclerViews can re-use that video's itemViews once they already swipe off with the screen, it shall takes much better performance improvement.

Then i tried to have a particular RecycledViewPool to propagating to every nested RecyclerViews.

public class MainActivity extends Activity {
    private RecyclerView.RecycledViewPool mViewPool;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // create the RecycledViewPool from first and re-use for each nested RecyclerViews.
        mViewPool = new RecyclerView.RecycledViewPool();
        ...
    }
}

Even i done this effort, i keep notice that the onCreateViewHolder method being performed and the inflate counter getting increase during i swipe the root RecyclerView circularly.

private static class VideoAdapter extends RecyclerView.Adapter<GridViewHolder> {
    private List<Video> mVideoList;

    private VideoAdapter(List<Video> videoList) {
        mVideoList = videoList;
    }

    // this method would always invoke during i swipe the RecyclerView.
    @Override
    public GridViewHolder onCreateViewHolder(ViewGroup container, int viewType) {
        Log.e("", String.format("createViewCount : %d", ++MainActivity.STAT_GAME_VIDEO_ITEM_COUNT));
        return new GridViewHolder(inflate(container, R.layout.game_video_item)) {};
    }
}

Is this idea of mine will work? or i've doing it wrong? I want to achieve this effect, any other advices even if that aren't about RecyclerView would be appreciative, thanks in advance.

Answer 1

By now, I used GridLayout instead of the nested RecyclerView, and recycling views which inside those GridLayout myself. But it is probably not a good way because my recycling logical was very simplicity. The application still a little bit stutter while fast scrolling, I haven't figure it out. As a viable ending, I push my code in github. Please advising me if you have ideas, thanks.
