swiperefreshlayout实现下拉小球式的刷新，供大家参考，具体内容如下
布局文件：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"android:layout_height="match_parent"android:paddingLeft="@dimen/activity_horizontal_margin"android:paddingRight="@dimen/activity_horizontal_margin"android:paddingTop="@dimen/activity_vertical_margin"android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"> <android.support.v4.widget.SwipeRefreshLayout android:id="@+id/swipeRefreshLayout" android:layout_width="wrap_content" android:layout_height="wrap_content" > <ListView android:id="@+id/listView" android:layout_width="match_parent" android:layout_height="wrap_content"> </ListView> </android.support.v4.widget.SwipeRefreshLayout></RelativeLayout>
MainActivity:
public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener{private static final int REFRESH_STATUS =0;private ListView myListView;private SwipeRefreshLayout mySwipeRefreshLayout;private ArrayAdapter<String> listAdapter;private List<String> listIDE = new ArrayList<String>(Arrays.asList("Visual Studio", "Android Studio", "Eclipse", "Xcode"));private Handler refreshHandler = new Handler(){ public void handleMessage(android.os.Message msg) { switch (msg.what) { case REFRESH_STATUS: listIDE.removeAll(listIDE); listIDE.addAll(Arrays.asList("C#", "Java", "C++","Object-C")); listAdapter.notifyDataSetChanged(); mySwipeRefreshLayout.setRefreshing(false); break; } };};protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); myListView = (ListView) findViewById(R.id.listView); mySwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout); mySwipeRefreshLayout.setOnRefreshListener(this); mySwipeRefreshLayout.setColorSchemeResources(android.R.color.holo_blue_bright, android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light); listAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,listIDE); myListView.setAdapter(listAdapter);}@Overridepublic void onRefresh() { refreshHandler.sendEmptyMessageDelayed(REFRESH_STATUS, 1500); }}
