使用Android系统自带的下拉刷新控件

首先布局:

xml version="1.0" encoding="utf-8"?>
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"
    >

            android:layout_width="wrap_content"
        android:layout_height="wrap_content">
                            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"/>

         

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
        }
    }
}
