Question

我正在通过此广播接收器发送通知，该报警器由警报管理员触发发送短信但我无法看到任何通知。

我还试图包含已发送的意图和交付意图，但不能在这里使用registerReciever。

这是我的代码。

广播接收器

public class MyReceiver extends BroadcastReceiver {
    String SENT="sent";
    public final String tag="com.example.pritesh.smstimer";
    public MyReceiver() {

    }

    //@Override
    public void onReceive(Context context, Intent intent) {

            Log.i(tag,"Sending");
            NotificationManager notificationManager=  (NotificationManager)
                    context.getSystemService(Context.NOTIFICATION_SERVICE);
            Intent intent1=new Intent(context,Time_Picker.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context,0,intent1,0);
            Notification.Builder notification=new Notification.Builder(context)
                    .setContentTitle("SMS SENT")
                    .setContentText("Your SMS has Been Sent")
                    .setContentIntent(pendingIntent);


            SmsManager smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(Time_Picker.Phone,null, Time_Picker.Message, null, null);
            notificationManager.notify(0,notification.build());
            Toast.makeText(context, "Sms Sent", Toast.LENGTH_LONG).show();

    }
}

您是否在androidmanifest.xml中注册了接收器或者调用了registerReceiver来执行相同操作？我不认为它会发挥作用。

见这里：https://developer.android.com/guide/topics/manifest/receiver-element.html

在android中无法使用通知？
