RecyclerViewネストされたRecyclerViewを簡単に実現

Linearlayoutmanager RecyclerViewネストGridLayoutManager RecyclerViewレイアウト:GridLayoutManagerのrecyclerviewをLinearlayoutmanager RecyclerViewのitemviewとして使用
MainRecyclerAdapter.java

public class MainRecyclerAdapter extends RecyclerView.Adapter {
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_view_main, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.mButton.setText("Item " + position);
        if(holder.mRecyclerView.getAdapter()==null) {
            holder.mRecyclerView.setAdapter(new GridAdapter());
        }/*else {
            holder.mRecyclerView.getAdapter().notifyDataSetChanged();
        }*/

    }

    @Override
    public int getItemCount() {
        return 10;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public final AppCompatButton mButton;
        public final RecyclerView mRecyclerView;

        public ViewHolder(View itemView) {
            super(itemView);
            mButton = (AppCompatButton) itemView.findViewById(R.id.button);
            mRecyclerView = (RecyclerView) itemView.findViewById(R.id.recyclerView);
            RecyclerView.LayoutManager manager = new GridLayoutManager(itemView.getContext(), 4);
            manager.setAutoMeasureEnabled(true);
            mRecyclerView.setLayoutManager(manager);
        }
    }
}

注意が必要なのはGridLayoutManagerがsettAutoMeasureEnabled(true)を適応高さに設定することです***
onBindViewではitemのrecyclerviewにアダプタが設定されているかどうかを判断する必要がありますが、設定を繰り返すとスライドがスムーズになりません***
GridAdapter.java

public class GridAdapter extends RecyclerView.Adapter {
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_view_grid, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.mTextView.setText("Grid "+position);
      }

    @Override
    public int getItemCount() {
        return 8;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public final AppCompatTextView mTextView;

         public ViewHolder(View itemView) {
            super(itemView);
             mTextView= (AppCompatTextView) itemView.findViewById(R.id.textView);
         }
    }
}
