我正在尝试使用RecyclerViews来构建像Pinterest交错排列的东西.但是,虽然LinearLayoutMnager和GridLayoutManager在同一代码中运行良好,但用StaggeredGridLayoutManager替换它不会显示任何项目.在代码中放置断点表明它获取了项目计数和项目,但没有提供任何内容.关于我失踪的任何想法？

final RecyclerView rView = (RecyclerView) findViewById(R.id.app_list);
rView.setClickable(true);
rView.setHasFixedSize(true);
rView.setLayoutManager(new StaggeredGridLayoutManager(5, StaggeredGridLayoutManager.HORIZONTAL));
rView.setAdapter(new ItemListAdapter(this, getItems()));

用GridLayoutManger替换StaggeredGridLayoutManager一切正常.

rView.setLayoutManager(new GridLayoutManager(this, 5));

以下是适配器:

private static class ItemListAdapter extends RecyclerView.Adapter<ItemViewHolder> {
    private final LayoutInflater mInflater;
    private final ArrayList<ItemDetail> mList;

    public ItemListAdapter(Context context, ArrayList<ItemDetail> list) {
        mInflater = LayoutInflater.from(context);
        mList = list;
    }

    @Override
    public ItemViewHolder onCreateViewHolder(ViewGroup parent, int position) {
        final View view = mInflater.inflate(R.layout.item_blob, parent, false);
        return new ItemViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ItemViewHolder holder, int position) {
        holder.hive.showDrawable(mList.get(position).icon);
    }

    @Override
    public int …
