安卓：对于通知无图标 [英] Android: No icon for Notification

问题描述

我想创造一个通知，而不在状态栏（即没有展开的状态）的图标。我想自定义扩展的查看和设置的图标，仅此观点。但没有奏效。当我给0作为图标的构造函数，该图标消失，但通知也没有出现在扩展视图。

I wanted to create a notification without the icon in the status bar (the state that is not expanded). I tried the custom expanded view and set the icon for this view only. But it did not work. When I give 0 as icon to the constructor, the icon disappears but notification also does not appear in the expanded view.

的通知的通知=新通知（0，，0）;。

Notification notification = new Notification(0, "", 0);

我试了很多组合，但并没有拿出一个解决方案。顺便说一句，我知道这是工作，因为我看到了一些应用程序这个功能。谢谢你。

I tried a lot of combinations but didn't come out with a solution. By the way, I know it is working because I saw this feature in some apps. Thanks.

推荐答案

QuickSettings这样做，当我看着那个code，我看到它使用的通知的默认构造函数，并推动其图标，通知栏的右侧。我认为它仍然使用空间，但没有图标。

QuickSettings did this and as I looked at that code I saw it uses the default constructor of Notification and pushes its icon to the right of the notification bar. I think it still uses space but has no icon.

有些code：

notification = new Notification();
notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_NO_CLEAR;
long hiddenTime = Constants.SDK_VERSION >= 9 ? -Long.MAX_VALUE : Long.MAX_VALUE;
notification.when = visible ? System.currentTimeMillis() : hiddenTime; // align
// left (0) / right (max) in status bar

编辑：哦，对不起，我错过了code的重要防线，其实他用一个占位符。但是，现在你有一些code， - ）

edit: oh sorry I missed an important line of code, in fact he uses a placeholder. But now you have some code ;-)

notification.icon = visible ? (status == Constants.STATUS_BLACK_ICON ? 
                            R.drawable.ic_logo_black : R.drawable.ic_logo_white)
                            : R.drawable.ic_placeholder;
