(a) Import method:

1. Import extras,library,sample into eclipse after download

2. You may get an error after importing, please change the dependent package location

(b) How to use: We generally use more is simple listview, of course, other situations such as gridview,webview, etc., the author also has a direct written control, we directly use the good


Let's take a look at the basic methods used
code for 1.XML layout files

<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 "    tools:context= "Com.example.testpulltoreresh.MainActivity" >    < Com.handmark.pulltorefresh.library.PullToRefreshListView        android:id= "@+id/pl_refresh"        android:layout_ Width= "Match_parent"        android:layout_height= "Match_parent"/></relativelayout>

2. Setting the Pulltorefresh Listener event

Mpulllist.setonrefreshlistener (New OnRefreshListener2 () {@Overridepublic void Onpulldowntorefresh ( Pulltorefreshbase Refreshview) {//drop-down refresh triggered event//Get formatted time string label = Dateutils.formatdatetime (Getapplicationcontext ( ), System.currenttimemillis (), Dateutils.format_show_time | Dateutils.format_show_date | Dateutils.format_abbrev_all);//Update Lastupdatedlabelrefreshview.getloadinglayoutproxy (). SetLastUpdatedLabel (Label )//////Open thread emulation interface fill data new Getdatatask (). Execute (); @Overridepublic void Onpulluptorefresh (Pulltorefreshbase refreshview) {//On Load triggered event///Open thread analog interface fill data new Getdatatask () . Execute ();}});

3. Set the drop-down, up-loading tips

Set the Pulltorefreshlistview mode Mpulllist.setmode (Mode.both);//Set the load prompt for Pullrefreshlistview on load Mpulllist.setmode ( Mode.both); Mpulllist.getloadinglayoutproxy (False, True). Setpulllabel ("pull-up loading ..."); mpulllist.getloadinglayoutproxy (False, True). Setrefreshinglabel ("Loading ..."); Mpulllist.getloadinglayoutproxy (False, True). Setreleaselabel ("Release load more .///Set Pullrefreshlistview load Prompt Mpulllist.getloadinglayoutproxy (true, false). Setpulllabel ("drop-down refresh ..."); Mpulllist.getloadinglayoutproxy (True, false). Setrefreshinglabel ("Loading ..."); Mpulllist.getloadinglayoutproxy (True , false). Setreleaselabel ("Loosen load more ...");

all code for my demo project

public class Mainactivity extends Activity {private Pulltorefreshlistview mpulllist;private linkedlist<string> Mlistitems;private arrayadapter<string> madapter;private string[] mstrings = {"I am very kind", "I am gentle", "I am Amoy", "I Am the Arirang", "I Is the big gray wolf, "I Am Sheep Sheep"}; @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (R.layout.activity_main); Initview (); Seteventlistener (); InitData ();} /** * Initialize control */private void Initview () {mpulllist = (Pulltorefreshlistview) Findviewbyid (R.id.pl_refresh);} /** * Set listener */private void Seteventlistener () {Mpulllist.setonrefreshlistener (new OnRefreshListener2 () {@Overridepublic void Onpulldowntorefresh (Pulltorefreshbase refreshview) {//drop-down refresh triggered event//Get formatted time string label = Dateutils.formatdatetime (Getapplicationcontext (), System.currenttimemillis (), Dateutils.format_show_time | Dateutils.format_show_date | Dateutils.format_abbrev_all);//Update Lastupdatedlabelrefreshview.getloadinglayoutproxy (). SetLastUpdatedLabel (Label );///Turn on thread emulation interface fill data new Getdatatask (). Execute ();} @Overridepublic void Onpulluptorefresh (Pulltorefreshbase refreshview) {//On Load triggered event///Open thread analog interface fill data new Getdatatask () . Execute ();}}); /** * Initialize data */private void InitData () {//Set Pulltorefreshlistview mode Mpulllist.setmode (Mode.both);// Sets the load prompt Mpulllist.setmode (mode.both) on Pullrefreshlistview loading, Mpulllist.getloadinglayoutproxy (False, True). Setpulllabel ("Pull load ..."); Mpulllist.getloadinglayoutproxy (False, True). Setrefreshinglabel ("Loading ..."); Mpulllist.getloadinglayoutproxy (False, True). Setreleaselabel ("Loosen load more ...");// The load hint Mpulllist.getloadinglayoutproxy (true, false) is set when the Pullrefreshlistview drop-down is loaded. Setpulllabel ("drop-down refresh ..."); Mpulllist.getloadinglayoutproxy (True, false). Setrefreshinglabel ("Loading ..."); Mpulllist.getloadinglayoutproxy (True , false). Setreleaselabel ("Loosen load more ..."); mlistitems = new linkedlist<string> (); Mlistitems.addall (Arrays.aslist ( mstrings)); madapter = new Arrayadapter<string> (this, Android. R.layout.simple_list_item_1, mlistitems); mpulllist.seTadapter (Madapter);} Private class Getdatatask extends Asynctask<void, Void, string[]> {@Overrideprotected string[] Doinbackground ( Void ... params) {try {thread.sleep (n);} catch (Interruptedexception e) {}return null;} @Overrideprotected void OnPostExecute (string[] result) {if (Mpulllist.isheadershown ()) {Mlistitems.addfirst ("I am the newly incorporated concubine --drop-down Refresh ");} else if (Mpulllist.isfootershown ()) {mlistitems.addlast ("I am the concubine that put you back in your Arms");} Madapter.notifydatasetchanged ();//Call Flush complete mpulllist.onrefreshcomplete (); Super.onpostexecute (result);}}
