从查询SMS，CALL和CONTACT中获取正确的数字

Question

我需要从Contact，短信和呼叫查询中检索一个唯一的号码。

联系人，短信和电话的代码是：

从短信中检索数字：

Cursor cursor = context.getContentResolver().query(SMS_URI_ALL, null, null, null, null);
if (cursor.getCount() > 0) {
String address;
if (cursor.moveToFirst()) {
do {
    address = cursor.getString(cursor.getColumnIndex("address"));
}
}   
}

从通话中检索数字：

Cursor cursor = context.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, where, null, null);
int number = cursor.getColumnIndex(CallLog.Calls.NUMBER);
while (cursor.moveToNext()) {
    String phNumber =cursor.getString(number);
    phNumber = PhoneNumberUtils.formatNumber(cursor
        .getString(number));
}

从联系人中检索数字：

String where = ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1";
Cursor cursor = context.getContentResolver().query(Data.CONTENT_URI,
    null, where, null, null);
if (cursor.getCount() > 0) {
String number = null;
try {
    while (cursor.moveToNext()) {
        number = cursor.getString(cursor
                .getColumnIndex(Phone.NORMALIZED_NUMBER));
    }
}
}

有时我用+39检索数字，有些则没有。 我如何获得一个唯一的数字？
