Google官方版下拉刷新控件SwipeRefreshLayout解析

效果图如下：

布局文件:

<?xml version="1.0" encoding="utf-8"?>  
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
    android:id="@+id/swipe"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    tools:context="com.lg.swiperefreshlayoutdemo.MainActivity">  
  
    <RelativeLayout  
        android:layout_width="match_parent"  
        android:layout_height="match_parent">  
  
        <ListView  
            android:id="@+id/listview"  
            android:layout_width="match_parent"  
            android:layout_height="match_parent" />  
  
    </RelativeLayout>  
  
</android.support.v4.widget.SwipeRefreshLayout>

MainActivity中代码：

public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {  
    private SwipeRefreshLayout swipeRefreshLayout;  
    private ListView listView;  
    private String[] names = new String[]{"郭靖", "黄蓉", "杨过", "小龙女"};  
  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe);  
        swipeRefreshLayout.setOnRefreshListener(this);  
  
        listView = (ListView) findViewById(R.id.listview);  
    }  
  
    @Override  
    public void onRefresh() {  
        listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, names));  
        swipeRefreshLayout.setRefreshing(false);  
        Toast.makeText(this, "刷新成功", Toast.LENGTH_SHORT).show();  
    }  
}

很简单，可以根据具体的需求而更改
