Reprint with reference to ：http://blog.csdn.net/sange77/article/details/73753037

The other day , Write a horizontal list , I think it will be vertical at ordinary times listview Do it sideways , It's troublesome . later , Find out RecycleView This product can realize , The experience effect is also very good ！
## See the effect

## Code up

• gradle I quote

compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'

• Activity

public class CustomViewActivity extends Activity {
      private RecyclerView recyclerView; private MyRecyclerViewAdapter mAdapter = new MyRecyclerViewAdapter(); @Override protected void onCreate(@Nullable Bundle savedInstanceState) {
      super.onCreate(savedInstanceState); setContentView(R.layout.activity_custom_view); initView(); } private void initView() {
      recyclerView = (RecyclerView) findViewById(R.id.rv_custom_view); recyclerView.setAdapter(mAdapter); LinearLayoutManager llm = new LinearLayoutManager(this); llm.setOrientation(LinearLayoutManager.HORIZONTAL);//  Set to a horizontal layout  recyclerView.setLayoutManager(llm); recyclerView.addItemDecoration(new DividerItemDecoration(this,DividerItemDecoration.HORIZONTAL));//  Set the split line  } 

Be careful ：LinearLayoutManager.HORIZONTAL Want to be with DividerItemDecoration.HORIZONTAL Keep it up all the time , Will have a normal split line effect

• Activity XML

<?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:gravity="center_horizontal">
    <android.support.v7.widget.RecyclerView android:id="@+id/rv_custom_view" android:layout_width="match_parent" android:layout_height="wrap_content"/>
</LinearLayout>

• MyRecyclerViewAdapter

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.MyViewHolder> {
      @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
      View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_recyclerview,parent,false); return new MyViewHolder(view); } @Override public void onBindViewHolder(MyViewHolder holder, int position) {
      } @Override public int getItemCount() {
      return 9; } class MyViewHolder extends RecyclerView.ViewHolder{
      public MyViewHolder(View itemView) {
      super(itemView); } } } 

• item_recyclerview

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="wrap_content">

    <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text=" Test text " android:textSize="18sp" android:textStyle="bold"/>
    <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text=" This is the details ....."/>
</LinearLayout>

**item Do you want to adapt to full screen Control size , The main change is item_recyclerview.xml Mid root layout android:layout_width and android:layout_height **
ok, That's all. ！
