android Notification不会触发BroadcastReceiver的onReceive

Question

是否可以通知广播接收器？

我试过这段代码,但它不起作用.

创建通知但是当我点击它时没有任何反应.

注意:当我将notificationIntent更改为从MyBroadcastReceiver.class指向活动(如MainActivity.class)时,它可以正常工作.

通知创建:

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(
        Context.NOTIFICATION_SERVICE);

    int notificationIconId = XXXXXX
    Notification notification = new Notification(
        notificationIconId,
        XXXXXX,
        System.currentTimeMillis()
    );

    CharSequence contentTitle = XXXXXXX
    CharSequence contentText = XXXXXX

    Intent notificationIntent = new Intent(context,MyBroadcastReceiver.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
    notificationManager.notify(1,notification);

这是BroadcastReceiver

public static class MyBroadcastReceiver extends BroadcastReceiver {

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

 }
}

在AndroidManifest.xml中

<receiver android:name=".MyBroadcastReceiver" />

从你的代码......

PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

在创建PendingIntent目标a时BroadcastReceiver,您必须使用getBroadcast(...)而不是getActivity(...).

请参阅PendingIntent.getBroadcast(Context context,int requestCode,Intent intent,int flags)

另外,不要创建Intent这样的...

Intent notificationIntent = new Intent(context,MyBroadcastReceiver.class);

这是一个明确的Intent,它针对特定的类(通常用于启动特定的Activity类).

而是Intent用'动作' 创建'广播' ,例如......

Intent notificationIntent = new Intent(MyApp.ACTION_DO_SOMETHING);

您还需要为清单<intent-filter>的<receiver android:name=".MyBroadcastReceiver" />部分指定一个部分.
