英文:
how to reset badge count when android app opens on android
问题
打开应用后，我希望徽章计数被移除。目前，只有当我通过锁定屏幕上的推送消息打开应用时，徽章计数才会被移除。因此，我也可以这样提问：“如何从锁定屏幕中移除推送消息”。
使用这段代码，我可以检索通知：
@Override
protected void onStart() {
super.onStart();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
StatusBarNotification[] notifications = notificationManager.getActiveNotifications();
for (StatusBarNotification statusBarNotification : notifications) {
statusBarNotification.getNotification().number = 0;
}
}
}
但是，当将数字设置为0时，什么也不会发生。
英文:
After I open the App, I want the badge count to be removed. Right now, it only gets removed when I open the App via the Push message in the lock screen. The push message then gets removed from the lock screen, so I could also phrase this question as "How to remove push message from lock screen".
With this code I can retrieve the notification:
@Override
protected void onStart() {
super.onStart();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
StatusBarNotification[] notifications = notificationManager.getActiveNotifications();
for (StatusBarNotification statusBarNotification : notifications) {
statusBarNotification.getNotification().number = 0;
}
}
}
But nothing happens when settings the number to 0.
