我想通过contentObserver阻止SMS。为此，我想先获取SMS的电话号码。我该怎么做才能得到这个号码？这是我的代码，只需计算短信的数量。通过contentObserver阻止传出短信

setContentView(R.layout.main);
setReceiver();
}
private SmsSentCounter smsSentObserver = new SmsSentCounter(new Handler());
private int sms_sent_counter = 0;
private void setReceiver() {
this.getContentResolver().registerContentObserver(
Uri.parse("content://sms"), true, smsSentObserver);
}
class SmsSentCounter extends ContentObserver {
public SmsSentCounter(Handler handler) {
super(handler);
// TODO Auto-generated constructor stub
}
@Override
public void onChange(boolean selfChange) {
// TODO Auto-generated method stub

System.out.println ("Calling onChange new");
super.onChange(selfChange);
Cursor sms_sent_cursor = SMSObserver4.this.managedQuery(Uri
.parse("content://sms"), null, "type=?",
new String[] { "2" }, null);
if (sms_sent_cursor != null) {
if (sms_sent_cursor.moveToFirst()) {
sms_sent_counter++;
System.out.println("test" + sms_sent_counter);
}
}
Uri phoneUri = Uri.withAppendedPath(Contacts.Phones.CONTENT_FILTER_URL, Address);
if (phoneUri != null) {
Cursor phoneCursor = getContentResolver().query(phoneUri, new String[] {Phones._ID, Contacts.Phones.PERSON_ID}, null, null, null);
if (phoneCursor.moveToFirst()) {
long person = phoneCursor.getLong(1); // this is the person ID you need
}
}
}catch(Exception e)
{}
}
}
