Notifcation Access Denied - Android

Question

我正在创建一个Android应用来访问通知。到目前为止，我的NotificationListenerService无法访问通知。它不在下面显示的允许应用程序通知访问列表中。我怎么能启用它？我的 Manifest.xml，MainActivity.java和MyNotificationListener.java 如下所示

的Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="me.shikanga.NotificationListen2" >

    <uses-permission android:name="android.permission.WRITE_EXRERNAL_STORAGE"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:resizeableActivity = "true">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service
            android:name=".MyNotificationListener"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"
            >
            <intent-filter>
                <action android:name="android.service.notification.MyNotificationListener"/>
            </intent-filter>
        </service>
    </application>

</manifest>

MyNotificationListener.java

        super.onNotificationPosted(sbn, rankingMap);

    String pack = sbn.getPackageName();
    String ticker="";
    if(sbn.getNotification().tickerText.toString()!=null)
    {
        ticker=sbn.getNotification().tickerText.toString();
    }
    Bundle extras=sbn.getNotification().extras;
    String title=extras.getString("android.title");
    String text= extras.getCharSequence("android.text").toString();
    int id1= extras.getInt(Notification.EXTRA_SMALL_ICON);
    Bitmap id = sbn.getNotification().largeIcon;

    Toast.makeText(getApplicationContext(),pack +title+text, Toast.LENGTH_SHORT).show();
    Log.e("Posted", pack+ticker+title+text);

            }
        }
    });

    stopButton.setOnClickListener(new OnClickListener()
        {
            public void onClick(View v)
            {
                try

//Check of notification acccess is enabled
public boolean checkNotificationEnabled()

    String enabledListeners = Settings.Secure.getString(context.getContentResolver(), "enabled_notification_listeners");
    String packageName= getPackageName();
    if (enabledListeners.contains(packageName))
    {
        return true;
    }
    else
        {
            return false;
        }
}
}

我应该在哪里修改？谢谢。 jerryshikanga@gmail.com

据我所知，您无法以编程方式启用通知。在每台设备中，您都必须打开设备设置，并允许访问任何想要阅读通知的应用程序。
