Pulltorefresh implementation of pull-down refresh and pull-up loading

First, import the library
After downloading the source code (HTTPS://GITHUB.COM/CHRISBANES/ANDROID-PULLTOREFRESH), there is a library project, add Project to eclipse;

Second, the Import project
1. After the new project, right-click->properties->android->add Select the library above

2.main_activity.xml

<?xml version= "1.0" encoding= "Utf-8"?><linearlayout xmlns:android="Http://schemas.android.com/apk/res/android"  Android:layout_width="Fill_parent"android:layout_height="Fill_parent"  Android:orientation="vertical"android:background="#ffffff">                     <!--The Pulltorefreshlistview replaces a standard ListView widget.    <Com.handmark.pulltorefresh.library.PullToRefreshListView        Android:id="@+id/pull_refresh_list"        Android:layout_width="Fill_parent"        Android:layout_height="Fill_parent"        Android:cachecolorhint="#00000000"        Android:divider="#19000000"        Android:dividerheight="4DP"        Android:fadingedge="None"        android:fastscrollenabled="false"        android:footerdividersenabled="false"        android:headerdividersenabled="false"        Android:smoothscrollbar="true"/></linearlayout>

Com.handmark.pulltorefresh.library.PullToRefreshListView is equivalent to the ListView control, which replaces the code that was the ListView control.

Other than that:

1. Set the code to pull up or down to refresh:

Mpullrefreshlistview.setmode (mode.pull_from_end);//Pull down Refresh

Mpullrefreshlistview.setmode (Mode.pull_from_start);//Pull up Refresh

Mpullrefreshlistview.setmode (Mode.both);//flush at both ends

2. Pull-up loading settings text, these three lines change the text of the bottom part

Mexpandlist. SetMode(Mode. BOTH); Mexpandlist. Getloadinglayoutproxy(False, True). Setpulllabel(GetString (R. String. Pull_to_load)); Mexpandlist. Getloadinglayoutproxy(False, True). Setrefreshinglabel(GetString (R. String. Loading)); Mexpandlist. Getloadinglayoutproxy(False, True). Setreleaselabel(GetString (R. String. Release_to_load)); 

3. Implementation of pull-up event monitoring, only need to implement ONREFRESHLISTENER2 on it, while SetMode (Mode.both)
