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(); } }
