如果使用了

import android.provider.Contacts;
import android.provider.Contacts.People;

就要特別注意一下，
因為在android 2.0 SDK當中不建議使用，
請改用

import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;

要取得聯絡人的姓名sample code如下:

final Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while(people.moveToNext())
{
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
}
people.close();

奇怪的事，如果要取得聯絡人的電話
如果用

int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
String phone = people.getString(nameFieldColumnIndex); 
//nameFieldColumnIndex return回來的值總是 ─1，

上網google了一下，找到瞭解法，

1. 首先找到目標聯絡人的 _ID，例如要找第一個聯絡人的_ID

Cursor target = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
target.moveToFirst();
String contactId = cursor.getString(target.getColumnIndex(ContactsContract.Contacts._ID));

2. 接著透過_ID，來找電話號碼，電話號碼可能不只有一個，所以先判斷有無電話號碼

String IsPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

3. 如果有電話，接著再去query電話號碼

if( (Integer.parseInt(IsPhone) > 0) )
{
Cursor phoneNumber = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null); 
while (phones.moveToNext())
{
String strPhoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

}
}

** 如果要查詢e-mail，程式如下

Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);

while (emails.moveToNext())
{ 
String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));

}

另外
Java代码

Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);     
while (cursor.moveToNext())   
{      
    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));  
    String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));  
    if (Boolean.parseBoolean(hasPhone))   
    {  
        Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);       
        while (phones.moveToNext())   
        {        
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));      
        }       
        phones.close();      
    }      
    Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,null, null);  
    while (emails.moveToNext())   
    {                   
        String emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.CommonDataColumns.DATA));  
    }      
    emails.close();     
}     
cursor.close();
