在我的Android应用中，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？
答案 0 :(得分：3)
Android没有此特定功能。
替代方案可能是显示数字的通知，但在正常情况下应用程序图标本身无法使用。
如果你真的想破坏设计指南，你可以创建一个看起来像你的应用程序图标的小部件，小部件可以更好地控制它的绘制方式。一些应用程序已经发布用于Gmail，Google Voice，标准消息应用程序，并且错过了调用电话应用程序，并且它们伪装成常规应用程序图标，因此它是可能的。我并不是真的推荐这种方法，但可以使用。

1。 使用ShortcutBadger库进行徽章计数
dependencies {
compile 'me.leolin:ShortcutBadger:1.1.4@aar'
}
