【英文标题】：Onitem Click functionality to Contact application in android

【问题描述】：

我是 android 新手，我正在开发一个联系人应用程序，我在 Listview 中获取联系人姓名和联系人号码。 我的问题是我不知道如何实现 OnClick 来获取特定的名称和号码。

以下是我到目前为止尝试过的（MainActivity）

 public class MainActivity extends ListActivity 
 ListView  lv;
Cursor cursor1;

 @Override
 protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
   // lv=(ListView)findViewById(R.id.list);
    cursor1=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,null,null,null);
    startManagingCursor(cursor1);
    String[] from=ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,ContactsContract.CommonDataKinds.Phone.NUMBER,ContactsContract.CommonDataKinds.Phone._ID;


    int[] to=android.R.id.text1,android.R.id.text2;

    SimpleCursorAdapter listadapter = new SimpleCursorAdapter(this,android.R.layout.simple_expandable_list_item_2,cursor1,from,to);
    setListAdapter(listadapter);
    lv=getListView();
    lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);



@Override
public long getSelectedItemId() 
    return super.getSelectedItemId();


@Override
public int getSelectedItemPosition() 
    return super.getSelectedItemPosition();

activity_main.xml 文件..

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_
android:layout_ android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

  <ListView
    android:id="@android:id/list"
    android:layout_
    android:layout_

   />
 <TextView

android:layout_
android:text=""
android:id="@+id/tvPopUpItem"
/>
</RelativeLayout>
