Android之PullToRefresh的使用方法

標籤：

android studio 匯入 PullToRefresh

// 下載https://github.com/chrisbanes/Android-PullToRefresh// 解壓，得到 extras，sample，library(主要)Android-PullToRefresh-master -> library// 在你項目的根目錄建立一個lib目錄[PATH][app]    [src]    [res]    [build]    build.gradle    ...[build][gradle][lib]    // 將 library 重名名為 pull    [pull]        [src]        [res]        [build]        ... build.gradlesettings.gradle...// 修改 settings.gradle include ‘:app‘, ‘:lib:pull‘// 修改 [app]/build.gradledependencies {    // Library    compile project(‘:lib:pull‘)}// 建立 [lib]/[pull]/build.gradleapply plugin: ‘android-library‘android {    compileSdkVersion 17    buildToolsVersion "21.1.2"    sourceSets {    main {        manifest.srcFile ‘AndroidManifest.xml‘        java.srcDirs = [‘src‘]        resources.srcDirs = [‘src‘]        aidl.srcDirs = [‘aidl‘]        renderscript.srcDirs = [‘src‘]        res.srcDirs = [‘res‘]        assets.srcDirs = [‘assets‘]    }    }}// 完成   

使用 PullToRefresh 重新整理 ListView

//  在 activity_main.xml 增加一個 PullToRefreshListView<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <com.handmark.pulltorefresh.library.PullToRefreshListView    android:id="@+id/left_drawer"    android:layout_width="240dp"    android:layout_height="match_parent"    android:layout_gravity="start"    android:choiceMode="singleChoice"    android:dividerHeight="1px"    android:divider="#ff000000"    android:background="#ffffffff"    android:layout_alignParentTop="true"    android:layout_alignParentEnd="true"    android:layout_alignParentStart="true" /></RelativeLayout>// 在 MainActivitypublic class MainActivity extends Activity {    PullToRefreshListView lv;    private String[] mListTitle = {"姓名", "性別", "年齡", "居住地", "郵箱"};    private String[] mListStr = {"雨松MOMO", "男", "25", "北京",        "[email protected]"};    ListView mListView = null;    ArrayList<Map<String, Object>> mData = new ArrayList<Map<String, Object>>();    @Override    protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    // 擷取 PullToRefreshListView View    lv = (PullToRefreshListView) findViewById(R.id.left_drawer);    // ....    int lengh = mListTitle.length;    for (int i = 0; i < lengh; i++) {        Map<String, Object> item = new HashMap<String, Object>();        item.put("title", mListTitle[i]);        item.put("text", mListStr[i]);        mData.add(item);    }    // ...    SimpleAdapter adapter = new SimpleAdapter(this, mData, android.R.layout.simple_list_item_2,         new String[]{"title", "text"}, new int[]{android.R.id.text1, android.R.id.text2});    // 將 SimpleAdapter 設定到 PullToRefreshListView    lv.setAdapter(adapter);    // 重新整理事件監聽    lv.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener<ListView>() {        @Override        public void onRefresh(PullToRefreshBase<ListView> refreshView) {        // ...        new AsyncTask<Void, Void, Void>() {            @Override            protected Void doInBackground(Void... params) {            // 處理重新整理任務            try {                Thread.sleep(3000);            } catch (InterruptedException e) {                e.printStackTrace();            }            return null;            }            @Override            protected void onPostExecute(Void reslst)            {            // 更行內容，通知 PullToRefresh 重新整理結束            lv.onRefreshComplete();            }        }.execute();        }    });    }}
