Notification icon detection

Question

当在android的通知菜单中获取的json中插入新节点时，如何更改通知图标的颜色。

Answer 1

So if as in the comments, if what you want to do is display a notification with a color, and then update the same notification with a different color, you can try this:

First, when launching the notification set a fixed notificationID , for example:

notiManager.notify(123, notiBuilder.build());

I also think you may want to set the flag PendingIntent.FLAG_UPDATE_CURRENT on the pending intent of your notification.

And to set the color of the notification:

notiBuilder.setColor(ContextCompat.getColor(mContext, R.color.colorPrimary));

If you what to set a default color and then change it when a new one arrive I suggest you to save the count in the SharedPreferences and set the color according to the notification count
