Android SwipeRefreshLayout official pull-down refresh control introduction, android pull-down refresh

Google provides an official pull-down refresh control, SwipeRefreshLayout. I personally feel pretty good! Thanks to the traditional pull-down refresh, this gives a fresh feeling (Gmail mailbox has already used this pull-down refresh ).

SwipeRefreshLayout is in the V4 package, and corresponding examples are also provided in the corresponding V4 Demo.

SwipeRefreshLayout can have only one direct sub-View, which may be a ListView, a Layout, or other components to be refreshed.

SetOnRefreshListener is used to listen for refreshing actions. The SwipeRefreshLayout drop-down will have a refreshing effect and trigger this listener.

If you need a refresh animation, setRefreshing (true), stop: setRefreshing (false)

If you want to disable refresh animation and gesture response, ssetEnable (false) and restore: setEnable (true)

Google also provides V4 compatibility packages on its official website:

Take a look at the API:

Similar to XlistView, It is very convenient to use. Here is a simple example of the four commonly used methods.

1. layout file:

[Html]View plaincopy

1. <RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
2. Android: layout_width = "match_parent"
3. Android: layout_height = "match_parent">
5. <Android. support. v4.widget. SwipeRefreshLayout
6. Android: id = "@ + id/id_swipe_ly"
7. Android: layout_width = "match_parent"
8. Android: layout_height = "match_parent">
10. <ListView
11. Android: id = "@ + id/id_listview"
12. Android: layout_width = "match_parent"
13. Android: layout_height = "match_parent">
14. </ListView>
15. </Android. support. v4.widget. SwipeRefreshLayout>
17. </RelativeLayout>

2. MainActivty:

16. Public class MainActivity extends Activity implements SwipeRefreshLayout. OnRefreshListener
17. {
19. Private static final int REFRESH_COMPLETE = 0X110;

30. Switch (msg. what)
31. {
32. Case REFRESH_COMPLETE:
33. MDatas. addAll (Arrays. asList ("Lucene", "Canvas", "Bitmap "));
34. MAdapter. notifyDataSetChanged ();
35. MSwipeLayout. setRefreshing (false );
36. Break;
38. }
39. };
40. };
42. @ SuppressLint ("InlinedApi ")
43. Protected void onCreate (Bundle savedInstanceState)

49. MSwipeLayout = (SwipeRefreshLayout) findViewById (R. id. id_swipe_ly );
51. MSwipeLayout. setOnRefreshListener (this );
52. MSwipeLayout. setColorScheme (android. R. color. holo_blue_bright, android. R. color. holo_green_light,
53. Android. R. color. holo_orange_light, android. R. color. holo_red_light );
54. MAdapter = new ArrayAdapter <String> (this, android. R. layout. simple_list_item_1, mDatas );
55. MListView. setAdapter (mAdapter );
57. }
59. Public void onRefresh ()
60. {
61. MHandler. sendEmptyMessageDelayed (REFRESH_COMPLETE, 2000 );
63. }
64. }
