香港专业教育学院望着每一个地方的在An​​droid 4.0中使用，但没有运气的信息，甚至来源$ C ​​$ C ...现在...我知道肯定有应用程序，仍然做到这一点甚至在4.0 ... ...有还是一种方式。任何想法？

Ive looked every where for information and even source code for the use on android 4.0 but no luck... Now.. I know for certain there are apps that still do this even on 4.0... there is still a way. Any ideas?

推荐答案

我发现这里完整的示例应用程序，适用于Android的4.0

下面是重头戏：

要创建一个覆盖视图​​，设置时的LayoutParams的不要   设置为TYPE_SYSTEM_OVERLAY类型。

To create an overlay view, when setting up the LayoutParams DON'T set the type to TYPE_SYSTEM_OVERLAY.

相反，将其设置为<一个href="http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#TYPE_PHONE">TYPE_PHONE.

Instead set it to TYPE_PHONE.

使用以下标志：

<一个href="http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_NOT_TOUCH_MODAL">FLAG_NOT_TOUCH_MODAL

<一个href="http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_WATCH_OUTSIDE_TOUCH">FLAG_WATCH_OUTSIDE_TOUCH

<一个href="http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_NOT_TOUCH_MODAL">FLAG_NOT_TOUCH_MODAL ＆LT;＆LT;这个是非常重要的。没有它，焦点是考虑到叠加和软键（家庭，菜单，   等等）presses不会传递到下面的活动。

FLAG_NOT_TOUCH_MODAL << This one is quite important. Without it, focus is given to the overlay and soft-key (home, menu, etc.) presses are not passed to the activity below.

另外，还要确保你添加的<一个href="http://developer.android.com/reference/android/Manifest.permission.html#SYSTEM_ALERT_WINDOW">SYSTEM_ALERT_WINDOW许可权   的mainifest文件。

Also make sure you add the SYSTEM_ALERT_WINDOW permission to the mainifest file.
