这样是否能获取到通讯录里面的联系人姓名和电话

[多云转大雨]

Cursor c = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    while(c.moveToNext()) {
    	//取得联系人名字
    	int nameIndex = c.getColumnIndex(PhoneLookup.DISPLAY_NAME);
    	String name = c.getString(nameIndex);
    	//取得联系人号码	
    	int numberIndex = c.getColumnIndex(PhoneLookup.NUMBER);
    	String number = c.getString(numberIndex);
    }

姓名可以得到，但是电话号码不可以这样得。
要去另一个表里查，（估计可能大概是因为一个人可以有多个电话号码）

[zzt369880281]

List<Contact> contacts = new ArrayList<Contact>();
		Cursor cursor = context.getContentResolver().query(
				ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
		while (cursor.moveToNext()) {
			String id = cursor.getString(cursor
					.getColumnIndex(ContactsContract.Contacts._ID));
			String name = cursor.getString(cursor
					.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

			int isHas = Integer.parseInt(cursor.getString(cursor
							.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
			List<String> numbers = new ArrayList<String>();// 电话号码集
			
			//看看是否有电话号码
			if (isHas > 0) {
				Cursor c = context.getContentResolver().query(
						ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
						null,
						ContactsContract.CommonDataKinds.Phone.CONTACT_ID
								+ " = " + id, null, null);
				while (c.moveToNext()) {
					String number = c
							.getString(c
									.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
					numbers.add(number);
				}
				c.close();
			}
			Contact contact = new Contact();
			contact.setId(Integer.parseInt(id));
			contact.setName(name);
			contact.setNumbers(numbers);
			
			contacts.add(contact);
		}
		cursor.close();

我的目的是做个联系人备份，以XML格式储存到SD卡，下面是我的代码，但是每次只是保存最后一次的联系人，如图：

package com.wisher.main;

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.XMLWriter;

import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {
	private String id = null;
	private String name = null;
	private String phoneNumber = null;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		Button button = (Button) findViewById(R.id.btn);
		button.setOnClickListener(new OnClickListener() {

			public void onClick(View v) {
				try {
					getContact();
					Toast.makeText(MainActivity.this, "备份成功", Toast.LENGTH_SHORT).show();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		});
	}

	private void getContact() throws IOException {
		Cursor c = getContentResolver().query(
				ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

		while (c.moveToNext()) {
			id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
			name = c.getString(c
					.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
			Log.i("MainActivity", "Name --> " + name);
			Cursor phones = getContentResolver().query(
					ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
					null,
					ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = "
							+ id, null, null);

			XMLWriter output = new XMLWriter(new FileWriter(new File(
					"/mnt/sdcard/backup/phoneBackup.xml")));
			Document document = DocumentHelper.createDocument();
			// 使用addElement创建根元素
			Element rootElement = document.addElement("备份");
			Element articleElement = rootElement.addElement("属性");
			
			while (phones.moveToNext()) {
				phoneNumber = phones
						.getString(phones
								.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
				Log.i("MainActivity", "PhoneNumber --> " + phoneNumber);
				
				Element nameElement = articleElement.addElement("姓名");
				nameElement.setText(name);
				Element phoneElement = articleElement.addElement("电话");
				phoneElement.setText(phoneNumber);

				output.write(document);
				output.close();

			}
			phones.close();
		}
		c.close();
	}

}
