Question

我正在制作通知拦截器，删除所选应用程序通知。

我在通知侦听器服务中使用了代码段，

@Override
public void onNotificationPosted(StatusBarNotification sbn) {
    if(SettingsActivity.SettingsInfo.getInt(sbn.getPackageName(), R.drawable.unblock)==R.drawable.block)
        {
            if(Build.VERSION.SDK_INT<Build.VERSION_CODES.LOLLIPOP) 
               cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
            else 
               cancelNotification(sbn.getKey());
        }
}

但此代码仅清除可取消的通知。但我想删除所选应用程序的所有通知（也包括系统通知）。有没有办法做到这一点？

我也尝试了反射方法。

 NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                        manager.cancel(sbn.getTag(), sbn.getId());
                        Class localClass = Class.forName("android.os.ServiceManager");
                        Method getService = localClass.getMethod("getService", new Class[]{String.class});
                        if (getService != null) {
                            Object result = getService.invoke(localClass, new Object[]{Context.NOTIFICATION_SERVICE});
                            if (result != null) {
                                IBinder binder = (IBinder) result;
                                final INotificationManager iNotificationManager = INotificationManager.Stub.asInterface(binder);
                                int uid = 0;
                                try {
                                    uid = this.getPackageManager().getApplicationInfo(sbn.getPackageName(), 0).uid;
                                } catch (PackageManager.NameNotFoundException e) {
                                    e.printStackTrace();
                                }
                                iNotificationManager.cancelAllNotifications(sbn.getPackageName(), uid);
                            }
                        }

但我正在 Security Exception

Answer 1

如果您要取消其他应用的通知，则需要使用 NotificationListenerService

它有cancelNotification方法：

public class NotificationListener extends NotificationListenerService {
    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
      cancelNotification(sbn.getKey());
    }
}

Answer 2

试试这个并告诉我它是否有效：

@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
public class NotificationService extends NotificationListenerService {

@Override
public void onNotificationPosted(StatusBarNotification sbn) {
    // Store each StatusBarNotification object

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
        cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
        Log.d("Cncel ","Cancel not");
    }
    else {
        cancelNotification(sbn.getKey());
        Log.d("key ","Cancel not key");
    }
}

@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
    // Delete removed StatusBarNotification objects
}

}

Answer 3

感谢您的回复，从我的研究中我得到了解决方案

使用标记FLAG_NO_CLEAR
清除通知

对于api> 25，您可以延后通知

snoozeNotification(sbn.getKey(), Long.MAX_VALUE);

对于api＆gt; 23和＆lt; 26，有一种方法可以用于 ovveride组密钥并将它们分组到您的通知中，

statusbarnotification.setOverrideGroupKey("key");

少了api，

您需要 root访问权限或系统权限。然后你可以使用

iNotificationManager.cancelAllNotifications(sbn.getPackageName(), uid);

清除不可移除的通知
