如何從電話的聯系表中獲取email？

我想從手機的聯系列表中獲取不同的電子郵件地址，比如工作，家庭住址等。我用的下面的代碼，但是發現返回的結果是0。怎麼回事啊？

Cursor email = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
                Data.CONTACT_ID + " =" + id, null, null);
        while (email.moveToNext()) {
            emailAdd = email.getString(ContactsContract.CommonDataKinds.Email.TYPE_WORK);
            //ContactsContract.CommonDataKinds.Email.TYPE_HOME)
        }
        Log.v("anim", " emailAdd:    " + emailAdd);

我還需要獲取群組，昵稱，個人網站。

最佳回答：

Cursor emailCur = cr.query( 
    ContactsContract.CommonDataKinds.Email.CONTENT_URI, 
    null,
    ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
    new String[]{id}, null); 
while (emailCur.moveToNext()) { 
    // This would allow you get several email addresses
        // if the email addresses were stored in an array
    String email = emailCur.getString(
                  emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
    String emailType = emailCur.getString(
                  emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE)); 
} 
emailCur.close();
