Android swiperefreshlayout Official dropdown Refresh Control Introduction

The following app basically has a drop-down refresh function, used to basically use Xlistview or write a drop-down refresh, recently Google provides an official drop-down refresh control swiperefreshlayout, I feel good ah, see accustomed to the traditional drop-down refresh, It's a refreshing feeling (the app that seems to know is already using this drop-down refresh).

Google also gives the V4 Compatibility Pack on the official website:

By the way, take a look at the API chant:

and Xlistview similar, is very convenient to use, probably on these 4 commonly used methods, the following a simple example.

1. layout file:

[HTML]View Plaincopy

2. <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"
4. android:layout_width="match_parent"
6. android:layout_height="match_parent" >
10. <android.support.v4.widget.SwipeRefreshLayout
12. android:id="@+id/id_swipe_ly"
14. android:layout_width="match_parent"
16. android:layout_height="match_parent" >
20. <ListView
22. android:id="@+id/id_listview"
24. android:layout_width="match_parent"
26. android:layout_height="match_parent" >
28. </ListView>
30. </android.support.v4.widget.SwipeRefreshLayout>
34. </relativelayout>

2, Mainactivty:

[Java]View Plaincopy

2. Package Com.zhy.swiperefreshlayoutdemo;
6. Import java.util.ArrayList;
8. Import Java.util.Arrays;
10. Import java.util.List;
14. Import Android.annotation.SuppressLint;
16. Import android.app.Activity;
18. Import Android.os.Bundle;
20. Import Android.os.Handler;
22. Import Android.support.v4.widget.SwipeRefreshLayout;
24. Import Android.util.Log;
26. Import Android.widget.ArrayAdapter;
28. Import Android.widget.ListView;
32. Public class Mainactivity extends Activity implements Swiperefreshlayout.onrefreshlistener
34. {
38. private static final int refresh_complete = 0x110;
40. private Swiperefreshlayout mswipelayout;
42. private ListView Mlistview;
44. private arrayadapter<string> Madapter;
46. private List<string> Mdatas = new Arraylist<string> (Arrays.aslist ("Java", "Javascript", "C + +", "Ruby", "Json" ,
48. "HTML"));
52. private Handler Mhandler = new Handler ()
54. {
56. public void Handlemessage (android.os.Message msg)
58. {
60. switch (msg.what)
62. {
64. Case Refresh_complete:
66. Mdatas.addall (Arrays.aslist ("Lucene", "Canvas", "Bitmap"));
68. Madapter.notifydatasetchanged ();
70. Mswipelayout.setrefreshing (false);
72. Break ;
76. }
78. };
80. };
84. @SuppressLint ("Inlinedapi")
86. protected void OnCreate (Bundle savedinstancestate)
88. {
90. super.oncreate (savedinstancestate);
92. Setcontentview (R.layout.activity_main);
96. Mlistview = (ListView) Findviewbyid (R.id.id_listview);
98. Mswipelayout = (swiperefreshlayout) Findviewbyid (R.id.id_swipe_ly);
102. Mswipelayout.setonrefreshlistener (this);
104. Mswipelayout.setcolorscheme (Android. R.color.holo_blue_bright, Android. R.color.holo_green_light,
106. Android. R.color.holo_orange_light, Android. R.color.holo_red_light);
108. Madapter = New Arrayadapter<string> (this, Android.  R.layout.simple_list_item_1, Mdatas);
110. Mlistview.setadapter (Madapter);
114. }
118. public void Onrefresh ()
120. {
122. //LOG.E ("xxx", Thread.CurrentThread (). GetName ());
124. //UI Thread
128. Mhandler.sendemptymessagedelayed (Refresh_complete, 2000);
132. }
134. }

Well, at the end, I feel pretty good, so try it.
