Android RecyclerView 子条目（item）嵌套 RecyclerView

要实现的效果：
Android RecyclerView 子条目（item）嵌套 RecyclerView_第1张图片

MainActivity核心代码：

LinearLayoutManager layoutManager = new LinearLayoutManager(this);layoutManager.setOrientation(LinearLayoutManager.VERTICAL);mTvRecycler.setLayoutManager(layoutManager);mMyRecyclerViewAdapter = new MyRecyclerViewAdapter(TvStationActivity.this,mList);//给RecyclerView设置适配器mTvRecycler.setAdapter(mMyRecyclerViewAdapter);

activity_main.xml 布局：

<?xml version="1.0" encoding="utf-8"?>
