在 Android 中的应用程序图标上显示徽章计数

Question

在我的 Android 应用程序中，我想在 ios 等应用程序图标中显示推送通知徽章计数。

如何在应用程序图标中显示徽章计数？

Answer 1

Android 没有此特定功能。

另一种方法可能是有一个显示数字的通知，但应用程序图标本身在正常情况下无法使用。

如果您真的想打破设计准则，您可以制作一个看起来像您的应用图标的小部件，并且小部件可以更好地控制它的绘制方式。已经发布了一些应用程序来为 Gmail、谷歌语音、标准消息应用程序执行此操作，以及电话应用程序的未接来电，它们伪装成常规应用程序图标，因此这是可能的。我真的不推荐这种方法，但它是可用的。

1。 使用 ShortcutBadger 库进行徽章计数

        dependencies {
            compile 'me.leolin:ShortcutBadger:1.1.4@aar'
        }
