代码实例：

xml布局代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" tools:context="com.zking.laci.android09.MainActivity">
    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/recyc_main"
        ></android.support.v7.widget.RecyclerView>


</LinearLayout>

Java代码：

import android.widget.TextView;

public class MainActivity extends AppCompatActivity {


    private RecyclerView rv;
    private String[] names;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rv = (RecyclerView) findViewById(R.id.recyc_main);
        names = new String[]{"小白","小红","小白1","小红1"};
        //指定排列方式 不同的方式 不同的排版
        //rv.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,true));
        rv.setLayoutManager(new GridLayoutManager(this,2,GridLayoutManager.VERTICAL,false));
        rv.setAdapter(new MyAdapter());

    }

    class MyAdapter extends RecyclerView.Adapter{
        class Myholder extends RecyclerView.ViewHolder {

            private final TextView tv;

            public Myholder(View itemView) {
                super(itemView);
                tv = (TextView) itemView.findViewById(android.R.id.text1);
            }
        }

        @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 Myholder(v);
        }

        //绑定值
        @Override
        public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
                Myholder mh= (Myholder) holder;
                mh.tv.setText(names[position]);
        }

        @Override
        public int getItemCount() {
            return names.length;
        }
    }

}

希望我的代码能够帮到你们啦！
