如何在点击时设置通知以清除自身？

Question

如何设置我的通知以便在点击时自行清除？

我已设置autoCancel(true)但不起作用

我的代码：

Notification n  = new Notification.Builder(this)
                .setContentTitle("Update for you")
                .setContentText("Please click here to see the update information")
                .setLargeIcon(BitmapFactory.decodeResource(this.getResources(), 
                                                           R.drawable.ic_launcher))
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentIntent(pList)
                .setAutoCancel(true)
                .addAction(R.drawable.ic_read, "Read", pRead)
                .addAction(R.drawable.ic_list, "All Updates", pList)
                .build();

NotificationManager notificationManager = 
                      (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

notificationManager.notify(0, n);

Answer 1

在API 11中引入了setAutoCancel()的{​​{1}}。也许，您的最低版本低于API 11.

Notification.Builder也可在setAutoCancel()类中使用，该类已添加到支持库

中

NotificationCompat.Builder

Answer 2

使用FLAG_AUTO_CANCEL

n.flags |= Notification.FLAG_AUTO_CANCEL;

<强> SetAutoCancel（真）

func sectionForDegrees(degree: CGFloat){

    var result = "not defined"

    switch degree{
    case 0.1 ... 90:
        result = "1 \(degree)"
    case 90.1...180:
        result = "4 \(degree)"
    case -90.1...0:
        result = "2 \(degree)"
    case -180...(-90):
        result = "3 \(degree)"

    default:
        result = "not defined: \(degree)"
    }

    print(result)
}
