        //初始化数据List<String> list = new ArrayList<>();for (int i = 0; i < 10; i++) {list.add("This is computer "+String.valueOf(i));}RecyclerView recyclerView=(RecyclerView)findViewById(R.id.activity_recycler_view_recyclerView);MyRecyclerViewAdapter adapter=new MyRecyclerViewAdapter(this,list);recyclerView.setAdapter(adapter);//设置布局方式LinearLayoutManager linearLayoutManager=new LinearLayoutManager(this);linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);recyclerView.setLayoutManager(linearLayoutManager);// 瀑布式流布局                                                              // 3 表示布局的列数/*StaggeredGridLayoutManager layoutManager=new StaggeredGridLayoutManager(3,StaggeredGridLayoutManager.VERTICAL);recyclerView.setLayoutManager(layoutManager);*/
