I'm using registerContentObserver()
to be notified as the contacts are changed, but when I register for the content uri:People.CONTENT_URI
and when I observe in the log cat I'm getting the notify as "开发者_如何学运维false" even after changing the contact.
I have also overridden the deliverSelfNotification
to true. What am I doing wrong?
Not sure what your asking, your question is a bit vague.
Here is how I listen out for changes in the SMS content provider, you may find it useful
String url = "content://sms/";
Uri uri = Uri.parse(url);
getContentResolver().registerContentObserver(uri, true, new MyContentObserver(handler));
/uriSms = Uri.parse("content://sms/inbox");
Cursor c = getContentResolver().query(uriSms, null,null,null,null);
//Log.d("COUNT", "Inbox count : " + c.getCount());
}
class MyContentObserver extends ContentObserver {
public MyContentObserver(Handler handler) {
super(handler);
}
@Override public boolean deliverSelfNotifications() {
return false;
}
@Override public void onChange(boolean arg0) {
super.onChange(arg0);
Log.v("SMS", "Notification on SMS observer");
Message msg = new Message();
msg.obj = "xxxxxxxxxx";
handler.sendMessage(msg);
Uri uriSMSURI = Uri.parse("content://sms/");
Cursor cur = getContentResolver().query(uriSMSURI, null, null,
null, null);
cur.moveToNext();
String protocol = cur.getString(cur.getColumnIndex("protocol"));
if(protocol == null){
Log.d("SMS", "SMS SEND");
int threadId = cur.getInt(cur.getColumnIndex("thread_id"));
Log.d("SMS", "SMS SEND ID = " + threadId);
getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadId), null, null);
}
else{
Log.d("SMS", "SMS RECIEVE");
int threadIdIn = cur.getInt(cur.getColumnIndex("thread_id"));
getContentResolver().delete(Uri.parse("content://sms/conversations/" + threadIdIn), null, null);
}
}
If you are targeting anything newer than api level 3, you should use ContactsContract.Contacts.CONTENT_URI.
and then it's just a matter of: getContentResolver().registerContentObserver(ContactsContract.Contacts.CONTENT_URI, true, contentObserver);
You will not know what has changed with this method though.
