也是一个布局容器,只有一个子组件,类似scrollView

public class MainActivity extends AppCompatActivity {
SwipeRefreshLayout swipeRefreshLayout;

@Override  
protected void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
    setContentView(R.layout.activity\_main);  
    swipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.swipeLayout);  
    swipeRefreshLayout.setColorSchemeResources(R.color.colorAccent,  
            R.color.colorPrimary,  
            R.color.colorPrimary,  
            R.color.colorPrimaryDark);  
    swipeRefreshLayout.setSize(SwipeRefreshLayout.DEFAULT);;  
    swipeRefreshLayout.setProgressViewOffset(true, 0, 200);  
    swipeRefreshLayout.setProgressViewEndTarget(true, 100);  
    swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {  
        @Override  
        public void onRefresh() {  
            new Thread(new Runnable() {  
                @Override  
                public void run() {  
                    try {  
                       sleep(3000);  
                    } catch (InterruptedException e) {  
                        e.printStackTrace();  
                    }  
                    mHandler.sendEmptyMessage(1);  
                }  
            }).start();  
        }  
    });}  
    //handler  
    @SuppressLint("HandlerLeak")  
    Handler mHandler = new Handler(){  
        @Override  
        public void handleMessage(Message msg) {  
            super.handleMessage(msg);  
            switch (msg.what) {  
                case 1:  
                    Toast.makeText(MainActivity.this, "刷新成功", Toast.LENGTH\_SHORT).show();  
                    swipeRefreshLayout.setRefreshing(false);  
                    break;  
            }  
        }  
    };  
}

属性一运行便知道,在监听器里执行刷新任务,用handler通知主线程
