java - 按下通知按钮时未调用 BroadcastReceiver

Question

在我的 Service 的 onCreate 方法中，我通过执行以下操作创建通知:

String channelId = "001";
String channelName = "myChannel";

NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_NONE);
channel.setLightColor(Color.BLUE);
channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);

NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

if (manager != null) {
    manager.createNotificationChannel(channel);
    Notification notification;

    Intent myIntent = new Intent("alarmReceiver");

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, 0);

    Notification.Action action = new Notification.Action.Builder(
            Icon.createWithResource(this, R.drawable.ic_stop_black_24dp),
            "action string",
            pendingIntent).build();


    //Modify notification badge
    notification = new Notification.Builder(getApplicationContext(), channelId).setOngoing(true)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setCategory(Notification.CATEGORY_SERVICE)
            .addAction(action)
            .build();

    startForeground(101, notification);
}

上面Intent中的alarmReceiver在我的manifest中注册如下(看到this问题后做了如下操作):

<receiver android:name=".AlarmReceiver">
    <intent-filter>
        <action android:name="alarmReceiver" />
    </intent-filter>
</receiver>

这是我的 AlarmReceiver 类:

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.e("onReceive - ","was called");
    }
}

显示了通知和按钮，但是当我按下按钮时没有任何反应。

我不确定我做错了什么。任何帮助将不胜感激。

将 PendingIntent 设置为前台服务，并可能添加一个标志:

FLAG_UPDATE_CURRENT

PendingIntent pendingIntent = PendingIntent.getForegroundService(this, 0, myIntent, FLAG_UPDATE_CURRENT);

您的广播是隐式，因此如果您想使用getBroadcast()，最好显式通过提供intent 与接收器的 componentName。

例如:

intent.setComponent(new ComponentName("packagename","fully qualified class name"));

您是否在 list 中声明了该服务？
