首先布局:

<?xml version="1.0" encoding="utf-8"?><android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:id="@+id/refresh"    android:layout_height="match_parent"    >    <ScrollView        android:layout_width="wrap_content"        android:layout_height="wrap_content">            <TextView                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="我是系统自带的下拉刷新控件"                android:gravity="center"/>         </ScrollView></android.support.v4.widget.SwipeRefreshLayout>

Activity中调用

public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {    private SwipeRefreshLayout refresh;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        refresh = (SwipeRefreshLayout) findViewById(R.id.refresh);        //设置下拉刷新的箭头颜色        refresh.setColorSchemeResources(android.R.color.holo_red_light);        //设置下拉刷新的背景颜色为白色        refresh.setProgressBackgroundColorSchemeResource(android.R.color.white);        refresh.setOnRefreshListener(this);        refresh.setOnRefreshListener(this);    }    @Override    public void onRefresh() {        Toast.makeText(this, "下拉刷新成功", Toast.LENGTH_SHORT).show();        if (refresh.isRefreshing()) {//如果正在刷新            refresh.setRefreshing(false);//取消刷新        }    }}
