侦听应用程序通知设置中的更改

Question

我的应用程序能够触发一些通知。

我希望能够检测到用户何时更改通知设置，例如何时全局禁用它们，何时禁用一个频道，或者何时他切换“允许通知点”...

我已经尝试了NotificationListenerService方法：

public class AppNotificationListenerService extends NotificationListenerService {

    private static final String TAG = "AppNLS";

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d(TAG, "onCreate: ");
    }

    @Override
    public IBinder onBind(Intent intent) {
        Log.d(TAG, "onBind: ");
        return super.onBind(intent);
    }

    @Override
    public boolean onUnbind(Intent intent) {
        Log.d(TAG, "onUnbind: ");
        return super.onUnbind(intent);
    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        super.onNotificationPosted(sbn);
        Log.d(TAG, "onNotificationPosted: ");
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        super.onNotificationRemoved(sbn);
        Log.d(TAG, "onNotificationRemoved: ");
    }

    @Override
    public void onListenerConnected() {
        super.onListenerConnected();
        Log.d(TAG, "onListenerConnected: ");
    }

    @Override
    public void onListenerDisconnected() {
        super.onListenerDisconnected();
        Log.d(TAG, "onListenerDisconnected: ");
    }

    @Override
    public void onNotificationChannelModified(String pkg, UserHandle user, NotificationChannel channel, int modificationType) {
        super.onNotificationChannelModified(pkg, user, channel, modificationType);
        Log.d(TAG, "onNotificationChannelModified: ");
    }

    @Override
    public void onListenerHintsChanged(int hints) {
        super.onListenerHintsChanged(hints);
        Log.d(TAG, "onListenerHintsChanged: ");
    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn, RankingMap rankingMap) {
        super.onNotificationPosted(sbn, rankingMap);
        Log.d(TAG, "onNotificationPosted: ");
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap) {
        super.onNotificationRemoved(sbn, rankingMap);
        Log.d(TAG, "onNotificationRemoved: ");
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap, int reason) {
        super.onNotificationRemoved(sbn, rankingMap, reason);
        Log.d(TAG, "onNotificationRemoved: ");
    }

    @Override
    public void onNotificationRankingUpdate(RankingMap rankingMap) {
        super.onNotificationRankingUpdate(rankingMap);
        Log.d(TAG, "onNotificationRankingUpdate: ");
    }

    @Override
    public void onNotificationChannelGroupModified(String pkg, UserHandle user, NotificationChannelGroup group, int modificationType) {
        super.onNotificationChannelGroupModified(pkg, user, group, modificationType);
        Log.d(TAG, "onNotificationChannelGroupModified: ");
    }

    @Override
    public void onInterruptionFilterChanged(int interruptionFilter) {
        super.onInterruptionFilterChanged(interruptionFilter);
        Log.d(TAG, "onInterruptionFilterChanged: ");
    }

}

在清单中，我添加了服务：

<service android:name=".services.AppNotificationListenerService"
    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" >
    <intent-filter>
        <action android:name="android.service.notification.NotificationListenerService" />
    </intent-filter>
</service>

我已为我的应用授予通知访问权限：

服务创建一个适当结合，我看到onNotificationPosted()并onNotificationRemoved()从通知区域中显示通知时/移除。

但是，当我全局启用/禁用应用程序的通知时，没有调用任何方法。当我启用/禁用频道通知时，唯一调用的方法是onNotificationRankingUpdate()但在切换其他应用程序的频道时也会调用此方法 。我只需要从我的应用程序。

这是正确的方式还是我想要实现的目标是以另一种方式完成的？

正如另一个 SO 答案中发布的那样，API 28 添加了系统广播ACTION_NOTIFICATION_CHANNEL_BLOCK_STATE_CHANGED，ACTION_NOTIFICATION_CHANNEL_GROUP_BLOCK_STATE_CHANGED这应该适合您的需求（请参阅文档）。
