你可以把RecyclerView其实就类似于ListView(区别在于：它是没有横线在文字下方的)

其效果图如下：

XML代码如下：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="match_parent">    <android.support.v7.widget.RecyclerView        android:layout_width="match_parent"        android:layout_height="match_parent"        android:id="@+id/rv_main_list"></android.support.v7.widget.RecyclerView></LinearLayout>

JAVA代码如下：

public class MainActivity extends AppCompatActivity {    private RecyclerView rv_main_list;    private String[] names;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        rv_main_list = (RecyclerView) findViewById(R.id.rv_main_list);        names = new String[]{"没没","又有","花花","球球","哦哦","提提"};        //rv_main_list既可以横着也可以竖着        rv_main_list.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));        rv_main_list.setAdapter(new MyAdapter());    }    class MyAdapter extends RecyclerView.Adapter{        class MyViewHolder extends RecyclerView.ViewHolder{            public TextView textView;            public MyViewHolder(View itemView) {                super(itemView);                textView= (TextView) itemView.findViewById(android.R.id.text1);            }        }        //类似BaseAdapter中的getView的方法        //ViewHolder类似BaseAdapter中的ItemTag        @Override        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {            //解析布局文件            View v= getLayoutInflater().inflate(android.R.layout.simple_list_item_1,null);            return new MyViewHolder(v);        }        //绑定值        @Override        public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {            MyViewHolder myViewHolder= (MyViewHolder) holder;            myViewHolder.textView.setText(names[position]);        }        @Override        public int getItemCount() {            return names.length;        }    }}
