Note: If you want to put it in android studio, you need to export it in eclipse as an android studio project.

Code

Layout:

<LinearLayout 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"              android:orientation="vertical"              tools:context=".MyActivity">    <com.handmark.pulltorefresh.library.PullToRefreshListView        android:id="@+id/lv_main"        android:layout_width="fill_parent"        android:layout_height="fill_parent"></com.handmark.pulltorefresh.library.PullToRefreshListView></LinearLayout>

Configuration:

@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_my);        mList = new ArrayList<String>();        for (int i = 0; i < mStr.length; i++) {            mList.add(mStr[i]);        }        mListView = (PullToRefreshListView) findViewById(R.id.lv_main);//        mListView.setOnRefreshListener(new MyRefreshListener());        mListView.setOnRefreshListener(new MyRefreshListener2());        mMyAdapter = new MyAdapter();        mListView.setAdapter(mMyAdapter);        mListView.setMode(PullToRefreshBase.Mode.BOTH);        mListView.getLoadingLayoutProxy().setLastUpdatedLabel("setLastUpdatedLabel");        mListView.getLoadingLayoutProxy().setLoadingDrawable(getResources().getDrawable(R.drawable.ic_launcher));        mListView.getLoadingLayoutProxy().setPullLabel("setPullLabel");        mListView.getLoadingLayoutProxy().setRefreshingLabel("setRefreshingLabel");        mListView.getLoadingLayoutProxy().setReleaseLabel("setReleaseLabel");    }

PullToRefreshBase. Mode. BOTH indicates the pull-down and pull-up refresh modes.

class MyRefreshListener implements PullToRefreshBase.OnRefreshListener {        @Override        public void onRefresh(PullToRefreshBase refreshView) {        }    }    class MyRefreshListener2 implements PullToRefreshBase.OnRefreshListener2 {        @Override        public void onPullDownToRefresh(PullToRefreshBase refreshView) {            mList.clear();            for (int i = 0; i < mStr.length; i++) {                mList.add(mStr[i]);            }            new Thread(new MyRunnable()).start();        }        @Override        public void onPullUpToRefresh(PullToRefreshBase refreshView) {            for (int i = 0; i < mStr.length; i++) {                mList.add(mStr[i]);            }            new Thread(new MyRunnable()).start();        }    }

There are two listeners here. Let's briefly talk about PullToRefreshBase. OnRefreshListener2. Obviously, one is pull-up, and the other is pull-down refresh callback.

Public class MyActivity extends Activity {private PullToRefreshListView mListView; // pulltorefresh control private List <String> mList; // private String for storing data [] mStr = {"0", "1 ", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11 ", "12", "13", "14", "15", "16", "17", "18", "19"}; // data private MyAdapter mMyAdapter; // adapter // a latency, and then process private Handler mHandler = new Handler () {@ Override public void handleMessage (Message msg) {super. handleMessage (msg); switch (msg. what) {case 1: Log. I ("handleMessage", "handleMessage"); mListView. onRefreshComplete (); mMyAdapter. yydatasetchanged (); break ;}}; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_my); mList = new ArrayList <String> (); // initialize for (int I = 0; I <mStr. length; I ++) {mList. add (mStr [I]); // prepare data} mListView = (PullToRefreshListView) findViewById (R. id. lv_main); // mListView. setOnRefreshListener (new MyRefreshListener (); mListView. setOnRefreshListener (new MyRefreshListener2 (); // sets the listener mMyAdapter = new MyAdapter (); // initializes the adapter mListView. setAdapter (mMyAdapter); mListView. setMode (PullToRefreshBase. mode. BOTH); // The mode is pull up and pull down mListView. getLoadingLayoutProxy (). setLastUpdatedLabel ("setLastUpdatedLabel"); mListView. getLoadingLayoutProxy (). setLoadingDrawable (getResources (). getDrawable (R. drawable. ic_launcher); // The image mListView when loading. getLoadingLayoutProxy (). setPullLabel ("setPullLabel"); mListView. getLoadingLayoutProxy (). setRefreshingLabel ("setRefreshingLabel"); mListView. getLoadingLayoutProxy (). setReleaseLabel ("setReleaseLabel");} class MyRefreshListener implements PullToRefreshBase. onRefreshListener {@ Override public void onRefresh (PullToRefreshBase refreshView) {}} class MyRefreshListener2 implements PullToRefreshBase. onRefreshListener2 {@ Override public void onPullDownToRefresh (PullToRefreshBase refreshView) {mList. clear (); for (int I = 0; I <mStr. length; I ++) {// Add data mList. add (mStr [I]);} new Thread (new MyRunnable ()). start (); // execution latency} @ Override public void onPullUpToRefresh (PullToRefreshBase refreshView) {for (int I = 0; I <mStr. length; I ++) {// Add data mList. add (mStr [I]);} new Thread (new MyRunnable ()). start (); // execution latency} class MyAdapter extends BaseAdapter {@ Override public int getCount () {return mList. size () ;}@ Override public Object getItem (int I) {return mList. get (I) ;}@ Override public long getItemId (int I) {return I ;}@ Override public View getView (int I, View view, ViewGroup viewGroup) {if (view = null) {view = LayoutInflater. from (MyActivity. this ). inflate (R. layout. item, null); TextView TV = (TextView) view.findViewById(R.id.txt); TV. setText (mList. get (I);} else {TextView TV = (TextView) view.findViewById(R.id.txt); TV. setText (mList. get (I);} return view;} class MyRunnable implements Runnable {@ Override public void run () {try {Thread. sleep (2000); // latency 2 s} catch (InterruptedException e) {e. printStackTrace ();} Log. I ("MyRunnable", "MyRunnable"); mHandler. sendEmptyMessage (1 );}}}
