public class GridViewDemo extends AppCompatActivity {    private RecyclerView recyclerView;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_gridview_demo);        recyclerView = (RecyclerView)findViewById(R.id.recyclerView);                //这里的第二个参数6代表的是网格的列数        recyclerView.setLayoutManager(new GridLayoutManager(this, 6));        recyclerView.setAdapter(new GridAdapter());    }     class GridAdapter extends RecyclerView.Adapter {        @Override        public Holder onCreateViewHolder(ViewGroup parent, int viewType) {            View view = LayoutInflater.from(context).inflate(R.layout.item_horizontal_recyclerviedw, parent, false);            Holder holder = new Holder(view);            return holder;        }         @Override        public void onBindViewHolder(Holder holder, int position) {            holder.textView.setText("第" + position + "元素");        }         @Override        public int getItemCount() {            return 20;        }         class Holder extends RecyclerView.ViewHolder {            private TextView textView;            public Holder(View itemView) {                super(itemView);                textView = (TextView)itemView.findViewById(R.id.textView);            }        }    }}
