以编程方式检查Android系统安全通知访问设置

Question

有没有办法检查Android中是否以编程方式启用或禁用了以下设置？

Settings > Security > Device Administration > Notification Access > My App 

目前我正在通过以下方法从我的应用程序调用设置对话框,但如果设置已经启用,那么我不想提供此设置.

Intent intent = new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
startActivity(intent);

Answer 1

简单一点

  if (Settings.Secure.getString(this.getContentResolver(),"enabled_notification_listeners").contains(getApplicationContext().getPackageName())) 
    {
        //service is enabled do something
    } else {
        //service is not enabled try to enabled by calling...
       getApplicationContext().startActivity(new Intent(
            "android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"));
    }

根据您的问题,'else'部分是可选的

Answer 2

将状态保存在 onBind() 和 onUnbind() 的静态变量中对我有用。

public boolean onUnbind(Intent mIntent) {
    boolean mOnUnbind = super.onUnbind(mIntent);
    Common.isNotificationAccessEnabled = false;
    return mOnUnbind;
}

public IBinder onBind(Intent mIntent) {
    IBinder mIBinder = super.onBind(mIntent);
    Common.isNotificationAccessEnabled = true;
    return mIBinder;
}
