可以不断更新在通知区域中的文字？ [英] Possible to continuously update text in the notification area?

问题描述

我想一个放置在每一秒更新一次的通知区域持续性的文字。 setTicker（）在NotificationCompat.Builder类是行不通的，因为它隐藏在通知区域中其他一切。我只是希望把文字还有就是几个字符，只占用一小块通知区域。

I would like a to place persistent text in the notification area that updates once every second. setTicker() in the NotificationCompat.Builder class will not work, because it hides everything else in the notification area. I am only looking to place text there that is a few characters long, taking up only a small piece of the notification area.

我觉得这是可以做到的一种方式是通过调用setSmallIcon（），并以某种方式使用这个小图标区显示的文本。我把一个应用程序的通知的截图，我相信使用这种策略。请注意，165 KB / s的：

One way I think this can be done is by calling setSmallIcon(), and somehow using this small icon area to display text. I took a screenshot of an app's notification that I believe to be using this strategy. Notice the 165 KB/s:
