本文實例講述了Android編程基于Contacts讀取聯系人的方法。分享給大家供大家參考，具體如下：

Android Contacts簡介：

這里介紹安卓通訊錄數據庫。包括Android使用Contacts訪問SQLite的基本知識，并了解Android SQLite和Contacts的更多信息。谷歌改變了從版本1到版本2的Contacts數據庫。下面加以簡單介紹。

Contacts 讀取代碼：

package com.homer.phone; import java.util.ArrayList; import java.util.HashMap; import android.app.Activity; import android.database.Cursor; import android.os.Bundle; import android.provider.ContactsContract; import android.provider.ContactsContract.CommonDataKinds.Phone; import android.widget.ListView; import android.widget.SimpleAdapter; public class phoneRead extends Activity {  @Override  public void onCreate(Bundle savedInstanceState){   super.onCreate(savedInstanceState);   showListView();  }  private void showListView(){   ListView listView = new ListView(this);   ArrayList<HashMap<String, String>> list = getPeopleInPhone2();   SimpleAdapter adapter = new SimpleAdapter(          this,          list,          android.R.layout.simple_list_item_2,          new String[] {"peopleName", "phoneNum"},          new int[]{android.R.id.text1, android.R.id.text2}         );   listView.setAdapter(adapter);   setContentView(listView);  }  private ArrayList<HashMap<String, String>> getPeopleInPhone2(){   ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();   Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);  // 獲取手機聯系人   while (cursor.moveToNext()) {    HashMap<String, String> map = new HashMap<String, String>();    int indexPeopleName = cursor.getColumnIndex(Phone.DISPLAY_NAME); // people name    int indexPhoneNum = cursor.getColumnIndex(Phone.NUMBER);   // phone number    String strPeopleName = cursor.getString(indexPeopleName);    String strPhoneNum = cursor.getString(indexPhoneNum);    map.put("peopleName", strPeopleName);    map.put("phoneNum", strPhoneNum);    list.add(map);   }   if(!cursor.isClosed()){    cursor.close();    cursor = null;   }   return list;  } }

AndroidManifest.xml 權限

記得在AndroidManifest.xml中加入android.permission.READ_CONTACTS這個permission

復制代碼代碼如下:

<uses-permission android:name="android.permission.READ_CONTACTS" />

運行結果：
