TYPE_SYSTEM_OVERLAY在ICS [英] TYPE_SYSTEM_OVERLAY in ICS

问题描述

在蜂巢我能够创建TYPE_SYSTEM_OVERLAY系统的覆盖和接收触摸与FLAG_WATCH_OUTSIDE_TOUCH。

In Honeycomb I was able to create a system overlay with TYPE_SYSTEM_OVERLAY and receive touches with FLAG_WATCH_OUTSIDE_TOUCH.

现在ICS已经改变了一些东西。我仍然可以创建系统覆盖，但我不能得到触动。

Now ICS has changed something. I can still create the system overlay, but i can't get touches.

现在，我能够与TYPE_SYSTEM_ALERT创建相同的，并得到触动，但它只是抓住了touchevents，而不是通过他们就像在蜂窝。

Now, i am able to create the same with TYPE_SYSTEM_ALERT and get touches, but it just catches the touchevents, and not passing them on like in Honeycomb.

任何想法的？

亲切的问候

推荐答案

您所描述的一切都是真实的。这是presumably加强安全性，因为前者的行为是tapjacking攻击的来源。我写一个博客帖子最近这一变化。

Everything you describe is true. It is presumably to tighten up security, as the former behavior was the source of tapjacking attacks. I wrote a blog post recently about this change.

任何想法的？

不要使用其中任一。
