android獲取聯系人示例分享

復制代碼 代碼如下:
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;
 }
}


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" />
