Question

我对从一个部门向一项活动发送广播有问题。

这是我在服务班子里的:

Intent intent = new Intent();
intent.setAction(BROADCAST_ACTION);
sendBroadcast(intent);

我有许多活动,在我的一项活动中,我有:

   class MyBroadcast extends BroadcastReceiver {
            @Override
            public void onReceive(Context ctxt, Intent i) {


                System.out.println("received");

            }
        };

我面临的问题是,我的广播接收者不收任何东西!

帮助!

EDIT:

If I have many activities how can send a broadcast message to all of them. In other words can I apply the same broadcast receiver to all the activities !?

Answer 1

与其他人一样,你需要首先登记这些广播活动(见Flo的答复)。

For your other quesition (re: EDIT). If you are taking the same action, you should create an overall Activity, and have your other activities extend that activity..

然后,在这个超级班子里,在Resume实施广播接收器登记册,在Stop进行注册。

Answer 2

你们必须先登记广播接收人,然后才能得到任何东西。

Have a look at this question.
