按下 .addAction() 时 BroadcastReceiver 未收到

BroadcastReceiver not receiving when .addAction() is pressed

我想在不打开应用程序的情况下关闭来自 .addAction() 的通知。问题是按下按钮时没有任何反应,onReceive() 方法不会触发。

这是 MainActivity 上的代码:

 Intent notificationIntent = new Intent(mContext, MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
    notificationIntent.putExtra("id", SOMENUMBER);
    PendingIntent pIntent = PendingIntent.getBroadcast(mContext, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder notification = new NotificationCompat.Builder(mContext);
    notification.setContentTitle("");
    notification.setContentText(t);
    notification.setSmallIcon(R.mipmap.ic_launcher);
    notification.setOngoing(true);
    notification.addAction(R.mipmap.ic_launcher, "Dismiss", pIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(SOMENUMBER, notification.build());

在其他 class 我有接收器:

public class Notification extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent){
        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        manager.cancel(intent.getIntExtra("id", 0));
    }
}

AndroidManifest.xml 文件的接收者:

<receiver android:name=".MainActivity">
    <intent-filter>
        <action android:name="io.github.seik.Notification" />
    </intent-filter>
</receiver>

您的命名约定令人困惑。 Android 已经有一个 class 叫做 Notification,所以你可能不应该给你的接收器打电话 Notification :-(

如果 MainActivity 扩展 Activity 那么您需要有一个清单条目,如下所示:

<activity android:name=".MainActivity"/>

对于您的 BroadcastReceiver,您需要这样的清单条目:

<receiver android:name=".Notification"
    android:exported="true"/>

由于您正在使用明确的 Intent 来启动您的 BroadcastReceiver,因此您不需要为其提供 <intent-filter>。由于 BroadcastReceiver 将由 NotificationManager 启动,您需要确保它是 exported.

然后您需要创建 PendingIntent 以便它实际启动您的 BroadcastReceiver,因此更改此:

Intent notificationIntent = new Intent(mContext, MainActivity.class);

对此:

Intent notificationIntent = new Intent(mContext, Notification.class);
