首先，我知道这已经被问过：安卓按键自定义吐司。 这几乎是完全相同的副本，但我认为这是值得的基础上，它一直在应用程序中使用的事实，一个新的问题，即对Gmail的ICS（当你删除一个消息出现）。

First of all, I know this has been asked before: Android : Button in custom Toast. This is nearly an exact duplicate, but I think that it warrants a new question based on the fact that it's been used in apps, namely Gmail for ICS (it appears when you delete a message).

链接的问题说，这是不可能包括在吐司，因为吐司一个按钮 s不能集中。这是错误的，过时的，还是Gmail中找到一个解决的方法？

The linked question says that it's not possible to include a button in a Toast because Toasts cannot be focused. Is this wrong, outdated, or did Gmail find a way around it?

推荐答案

Gmail的撤消酒吧岂不等于举杯，这里是谷歌是如何做的。

The Gmail undo bar is't a toast, here is how Google did it

我想这回答了你的问题。
