RecyclerView的用法

MainActivity的代码如下：

package com.example.zhangmeng.recyclerview;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

public class MainActivity extends AppCompatActivity {
    private RecyclerView rv;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        rv=new RecyclerView(this);
        setContentView(rv);
        rv.setLayoutManager(new LinearLayoutManager(this));
        rv.setAdapter(new MyAdapter());
    }

}

　　MyAdapter:

 1 package com.example.zhangmeng.recyclerview;
 2 
 3 import android.support.v7.widget.RecyclerView;
 4 import android.view.LayoutInflater;
 5 import android.view.View;
 6 import android.view.ViewGroup;
 7 import android.widget.TextView;
 8 
 9 /**

11  */
12 class MyAdapter extends RecyclerView.Adapter {
13 
14 
15     @Override
16     public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
17 
18         return new ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item,null));
19     }
20 
21     @Override
22     public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
23         ViewHolder vh = (ViewHolder) holder;
24         vh.getTv_title().setText("Title"+position);
25         vh.getTv_content().setText("content"+position);
26 
27     }
28 
29     @Override
30     public int getItemCount() {
31         return 10;
32     }
33 }
34 
35 class ViewHolder extends RecyclerView.ViewHolder {
36     private TextView tv_title;
37     private TextView tv_content;
38     public ViewHolder(View itemView) {
39         super(itemView);
40         tv_title=(TextView) itemView.findViewById(R.id.textView_title);
41         tv_content=(TextView) itemView.findViewById(R.id.textView_content);
42     }
43 
44     public TextView getTv_title() {
45         return tv_title;
46     }
47     public TextView getTv_content() { return tv_content; }
48 
49 
50 }

Activitylayout:

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     xmlns:tools="http://schemas.android.com/tools"
 4     android:layout_width="match_parent"
 5     android:layout_height="match_parent"
 6     android:paddingBottom="@dimen/activity_vertical_margin"
 7     android:paddingLeft="@dimen/activity_horizontal_margin"
 8     android:paddingRight="@dimen/activity_horizontal_margin"
 9     android:paddingTop="@dimen/activity_vertical_margin"
10     tools:context="com.example.zhangmeng.recyclerview.MainActivity">
11 
12     <TextView
13         android:layout_width="wrap_content"
14         android:layout_height="wrap_content"
15         android:text="Hello World!" />
16 </RelativeLayout>

Itemlayout:

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:orientation="vertical" android:layout_width="match_parent"
 4     android:layout_height="match_parent">
 5 
 6     <TextView
 7                 android:layout_width="match_parent"
 8         android:layout_height="wrap_content"
 9         android:textAppearance="?android:attr/textAppearanceLarge"
10         android:text="Large Text"
11         android:id="@+id/textView_title"
12         android:layout_gravity="center_horizontal" />
13 
14     <TextView
15         android:layout_width="match_parent"
16         android:layout_height="wrap_content"
17         android:textAppearance="?android:attr/textAppearanceSmall"
18         android:text="Small Text"
19         android:id="@+id/textView_content" />
