Android 2.0 API 读取通讯录中电话号码的实例

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.widget.TextView;

public class Activity01 extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
TextView tv = new TextView(this);
String string = "";
super.onCreate(savedInstanceState);
//得到ContentResolver对象
ContentResolver cr = getContentResolver();
//取得电话本中开始一项的光标
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
//向下移动一下光标
while(cursor.moveToNext())
{
//取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = cursor.getString(nameFieldColumnIndex);
//取得电话号码
int numberFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.NUMBER);  //此行会报错，返回值=-1
String number = cursor.getString(numberFieldColumnIndex);

string += (contact+":"+number+"\n");
}
cursor.close();
//设置TextView显示的内容
tv.setText(string);
//显示到屏幕
setContentView(tv);
}
}

参考网上的资料，找到了正确读取联系人电话的方法：

android.app.Activity;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.database.Cursor;
import android.widget.TextView;
import android.content.ContentResolver;

public class Activity01 extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
TextView tv = new TextView(this);
String string = "";
super.onCreate(savedInstanceState);

//得到ContentResolver对象
ContentResolver cr = getContentResolver();
//取得电话本中开始一项的光标
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
//向下移动光标
while(cursor.moveToNext())
{
//取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = cursor.getString(nameFieldColumnIndex);
//取得电话号码
String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);

while(phone.moveToNext())
{
String PhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
string += (contact + ":" + PhoneNumber + "\n");
}
}
cursor.close();

//设置TextView显示的内容
tv.setText(string);
//显示到屏幕
setContentView(tv);

最后记得在AndroidManifest.xml声明读取联系人的API：<uses-permission android:name="android.permission.READ_CONTACTS"/>[/code]如果我们只想获取手机号如何操作呢？

Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);

把以上语句改为：

Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId + " AND " + ContactsContract.CommonDataKinds.Phone.TYPE + "=" + ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);

ContactsContract.CommonDataKinds.Phone.TYPE 表示联系人电话的类型，主要对应如下：
TYPE_MOBILE ： 手机号码
TYPE_HOME  ： 住宅电话
TYPE_WORK ： 公司电话
