2. Usage

Listview layout File

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/container"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.example.aa.MainActivity"    tools:ignore="MergeRootFrame" >    <com.handmark.pulltorefresh.library.PullToRefreshListView        xmlns:ptr="http://schemas.android.com/apk/res-auto"        android:id="@+id/listview"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:gravity="center"        android:listSelector="#00000000"        ptr:ptrMode="both" /></LinearLayout>

Common Methods

Package com. example. aa; import java. util. arrayList; import java. util. list; import com. handmark. pulltorefresh. library. pullToRefreshBase; import com. handmark. pulltorefresh. library. pullToRefreshBase. mode; import com. handmark. pulltorefresh. library. pullToRefreshBase. onLastItemVisibleListener; import com. handmark. pulltorefresh. library. pullToRefreshBase. onRefreshListener; import com. handmark. pulltorefresh. librar Y. pullToRefreshListView; import android. support. v7.app. actionBarActivity; import android. text. format. dateUtils; import android. widget. listView; import android. widget. toast; import android. OS. asyncTask; import android. OS. bundle; public class MainActivity extends ActionBarActivity {PullToRefreshListView pullToRefreshListView; ListView listView; @ Override protected void onCreate (Bundle savedInstanceState) {Super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); pullToRefreshListView = (PullToRefreshListView) findViewById (R. id. listview); pullToRefreshListView. setOnRefreshListener (new OnRefreshListener <ListView> () {@ Override public void onRefresh (PullToRefreshBase <ListView> refreshView) {String label = DateUtils. formatDateTime (getApplicationContext (), System. currentTimeMi Llis (), DateUtils.

"); // Release the refreshView. getLoadingLayoutProxy (). setRefreshingLabel (""); Toast. makeText (MainActivity. this, "refreshed", Toast. LENGTH_SHORT ). show (); new getdatatask(cmd.exe cute () ;}}); // The listview slides to the last pullToRefreshListView. setOnLastItemVisibleListener (new OnLastItemVisibleListener () {@ Override public void onLastItemVisible () {Toast. makeText (MainActivity. this, "listview to the end", Toast. LENGTH_SHORT ). show () ;}}); pullToRefreshListView. setMode (Mode. PULL_FROM_START); listView = pullToRefreshListView. getRefreshableView (); listView. setAdapter (new Adapter (this, getData ();/*** when the program comes in, refresh the data and automatically refresh */pullToRefreshListView. setRefreshing ();}/*** @ author admin * pullToRefreshListView. onRefreshComplete (); this sentence should be written asynchronously **/private class GetDataTask extends AsyncTask <Void, Void, String >{@ Override protected String doInBackground (Void... params) {try {Thread. sleep (500);} catch (InterruptedException e) {} return "" ;}@ Override protected void onPostExecute (String result) {super. onPostExecute (result); pullToRefreshListView. onRefreshComplete () ;}list <String> getData () {List <String> List = new ArrayList <String> (); for (int I = 0; I <100; I ++) {list. add ("ddd") ;}return list ;}}

 

Refresh Mode

 

// PullToRefreshListView. setMode (Mode. PULL_FROM_START); // pullToRefreshListView is pulled up. setMode (Mode. PULL_FROM_END); // use both the drop-down and pullToRefreshListView. setMode (Mode. BOTH); // do not enable the refresh function pullToRefreshListView. setMode (Mode. DISABLED );

Obtain the current refresh Mode

 

// Obtain the current refresh mode if (pullToRefreshListView. getMode () = Mode. BOTH) {Toast. makeText (MainActivity. this, "the current refresh mode is" + pullToRefreshListView. getMode (), Toast. LENGTH_SHORT ). show ();}

 

Set the refresh sound

 

/*** Add Sound Event Listener */SoundPullEventListener <ListView> soundListener = new SoundPullEventListener <ListView> (this); soundListener. addSoundEvent (State. PULL_TO_REFRESH, R. raw. a1); // start to refresh the display sound soundListener. addSoundEvent (State. RESET, R. raw. a2); // The sound soundListener displayed after the refresh is complete. addSoundEvent (State. REFRESHING, R. raw. a3); // The pullToRefreshListView sound is being refreshed. setOnPullEventListener (soundListener );

 

 

Set pull-down refresh and pull-up to load more listening Methods

 

PullToRefreshListView. setOnRefreshListener (new Refresh ()); /*** listener method ** @ author admin */class Refresh implements OnRefreshListener2 <ListView >{// drop-down @ Override public void onPullDownToRefresh (PullToRefreshBase <ListView> refreshView) {}// pull up @ Override public void onPullUpToRefresh (PullToRefreshBase <ListView> refreshView ){}}

 

Set the font color when refreshing

 

<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/tools" android: id = "@ + id/container" android: layout_width = "match_parent" android: layout_height = "match_parent" android: orientation = "vertical" tools: context = "com. example. aa. mainActivity "tools: ignore =" MergeRootFrame "> <com. handmark. pulltorefresh. library. pullToRefreshListView xmlns: ptr = "http : // Schemas.android.com/apk/res-auto "android: id =" @ + id/listview "android: background =" # ffffff "android: layout_width =" fill_parent "android: layout_height =" fill_parent "android: gravity = "center" android: listSelector = "#00000000" ptr: ptrHeaderTextColor = "# FF9900" ptr: ptrHeaderSubTextColor = "#330099" ptr: ptrMode = "both"/> <! -- PtrHeaderTextColor refresh the color of the prompt --> <! -- PtrHeaderSubTextColor refresh the color value of the suboption --> </LinearLayout>

Running result

 

Set the drop-down and pull-up fonts respectively.

 

// Obtain the ILoadingLayout startLayout = pullToRefreshListView displayed in the drop-down list. getLoadingLayoutProxy (true, false); startLayout. setPullLabel ("You can pull, pull... drop-down "); // The prompt startLayout is displayed when you just pull down the page. setRefreshingLabel ("good luck, refreshing... drop-down "); // startLayout when refreshing. setReleaseLabel ("You dare to release, I dare to refresh... drop-down list "); // The prompt displayed when a certain distance is reached // get the ILoadingLayout endLayout = pullToRefreshListView displayed when pulling up. getLoadingLayoutProxy (false, true); endLayout. setPullLabel ("You can pull, pull... pull up "); // The endLayout prompt is displayed when you pull down. setRefreshingLabel ("good luck, refreshing... pull up "); // endLayout when refreshing. setReleaseLabel ("You dare to release, I dare to refresh... "); // The prompt displayed when the distance is reached

 

Common xml configurations

True is better. --> <! -- PtrListViewExtrasEnabled Footer: how to add mPullRefreshListView. true indicates that the headView is added, that is, the headers are refreshed and rolled together when scrolling. --> <! -- PtrRotateDrawableWhilePulling: When the animation is set to rotate, the drop-down determines whether to rotate the animation. --> <! -- Ptr: ptrAnimationStyle; values: flip (flip animation) and rotate (rotation animation ). --> <! -- Ptr: ptrDrawable indicates the setting icon. --> </LinearLayout>

3. uncommon things

1. How do I disable log output?

By default, PullToRefresh enables log output. In PullToRefreshBase, You can see static final boolean DEBUG = true;

True: logs are output. False: No logs are output.
