下面App基本都有下拉刷新的功能,以前基本都使用XListView或者自己写一个下拉刷新,近期Google提供了一个官方的下拉刷新控件SwipeRefreshLayout,我感觉还不错啊,见惯了传统的下拉刷新,这个反而给人耳目一新的感觉(貌似知乎的APP已经使用这种下拉刷新了)。
Google也在官方网站给出了V4的兼容包:
顺便看一眼API呗:
和XlistView差不多,还是很方便使用的,大概就这4个常用的方法,下面贴个简单的例子。
1、布局文件:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.v4.widget.SwipeRefreshLayout android:id="@+id/id_swipe_ly" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/id_listview" android:layout_width="match_parent" android:layout_height="match_parent" > </ListView> </android.support.v4.widget.SwipeRefreshLayout> </RelativeLayout>
package com.zhy.swiperefreshlayoutdemo; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import android.annotation.SuppressLint; import android.app.Activity; import android.os.Bundle; import android.os.Handler; import android.support.v4.widget.SwipeRefreshLayout; import android.util.Log; import android.widget.ArrayAdapter; import android.widget.ListView; public class MainActivity extends Activity implements SwipeRefreshLayout.OnRefreshListener { private static final int REFRESH_COMPLETE = 0X110; private SwipeRefreshLayout mSwipeLayout; private ListView mListView; private ArrayAdapter<String> mAdapter; private List<String> mDatas = new ArrayList<String>(Arrays.asList("Java", "Javascript", "C++", "Ruby", "Json", "HTML")); private Handler mHandler = new Handler() { public void handleMessage(android.os.Message msg) { switch (msg.what) { case REFRESH_COMPLETE: mDatas.addAll(Arrays.asList("Lucene", "Canvas", "Bitmap")); mAdapter.notifyDataSetChanged(); mSwipeLayout.setRefreshing(false); break; } }; }; @SuppressLint("InlinedApi") protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mListView = (ListView) findViewById(R.id.id_listview); mSwipeLayout = (SwipeRefreshLayout) findViewById(R.id.id_swipe_ly); mSwipeLayout.setOnRefreshListener(this); mSwipeLayout.setColorScheme(android.R.color.holo_blue_bright, android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light); mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mDatas); mListView.setAdapter(mAdapter); } public void onRefresh() { // Log.e("xxx", Thread.currentThread().getName()); // UI Thread mHandler.sendEmptyMessageDelayed(REFRESH_COMPLETE, 2000); } }
效果图:
