有没有一种方法来共享多个嵌套RecyclerViews之间的相同的布局管理 [英] Is there a way to share a same LayoutManager between multiple nested RecyclerViews
问题描述
我正在开发的表示游戏列表，每场比赛的ItemView控件中的应用程序，我也有一个视频列表将显示。 preVIEW和结构如下。
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.
我部署RecyclerView作为窗口根视图，然后在视频，我用的网格式RecyclerView显示，所以在这里我们得到了一个嵌套RecyclerView结构。
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.
但有麻烦了，因为影片的数量是游戏之间的矛盾，我不想的视频列表的RecyclerView能够被滚动，所以最好的办法就是让观的高度伸展动态取决于它有多少行有。我听到了一个令人失望的结论说，没有办法从互联网上做到这一点。那是真的吗？任何其他能这样做呢？
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?
到目前为止，关于这个问题，我没有想法去解决它，所以我手动更改RecyclerView的高度作为一种临时解决方案。
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;
由于视频项目是完全一样的结构，这将是很好，如果这些RecyclerViews可以重新使用该视频的itemViews一旦他们已经与屏幕刷卡关闭的，应当采取更好的性能提升。
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.
然后我想有一个特殊的RecycledViewPool来传播到每一个嵌套RecyclerViews。
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();
...
}
}
即使我做了这方面的努力，我一直注意，正在执行的onCreateViewHolder方法和充气柜获得增长的时候，我刷卡根RecyclerView循环。
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)) {};
}
}
这是我的想法会工作吗？或者我已经做错了？我想达到这样的效果，任何其他建议，即使是不看好RecyclerView将AP preciative，在此先感谢。
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.
推荐答案
到现在为止，我用网格布局，而不是嵌套RecyclerView和回收的观点这里面的网格布局自己。但它可能不是一个好办法，因为我回收的逻辑很简单。该应用程序仍有点结巴，而快速滚动，我还没有弄明白。作为一个可行的结局，我把我的code在 github上。请通知我，如果你有想法，谢谢。
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.
