如何用LinearLayoutManager实现部分部分，用GridLayoutManager实现部分？

// 创建RecyclerView对象
RecyclerView recyclerView = findViewById(R.id.recyclerView);

// 创建LinearLayoutManager对象，并设置布局方向为垂直
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);

// 设置RecyclerView的布局管理器
recyclerView.setLayoutManager(layoutManager);

// 创建适配器并设置给RecyclerView
MyAdapter adapter = new MyAdapter(dataList);
recyclerView.setAdapter(adapter);

// 创建RecyclerView对象
RecyclerView recyclerView = findViewById(R.id.recyclerView);

// 创建GridLayoutManager对象，并指定每行的数量为2
GridLayoutManager layoutManager = new GridLayoutManager(this, 2);

// 设置RecyclerView的布局管理器
recyclerView.setLayoutManager(layoutManager);

// 创建适配器并设置给RecyclerView
MyAdapter adapter = new MyAdapter(dataList);
recyclerView.setAdapter(adapter);
