推荐答案

如果通过两个活动的应用程序，那么你的意思的真正的应用程序（即带有活动，回堆栈，和C）激活同一时间，那么没有（除了在一些专门的设备，用定制的API）。

If by "two active applications" then you mean real applications (i.e. with activities, back stack, &c) active at the same time, then no (except in some specialized devices, with custom APIs).

然而，有一个小窍门，你可以用它来实现类似的效果。与 android.permission.SYSTEM_ALERT_WINDOW （显示为画在其他应用程序，在Play商店），可以创建的从服务，并显示他们的窗口的应用。所以，你很可能得到这种方法你想要的效果。

However, there is a trick you can use to achieve a similar effect. Applications with the android.permission.SYSTEM_ALERT_WINDOW (displayed as "draw over other apps" in Play Store) can create windows from a service and show them. So you could probably get the effect you want with this method.

有一个名为突出一个开源库，它提供了一个易于使用的方式这种行为。你可能想看看吧。

There is an open source library called StandOut which provides this behavior in an easy to use manner. You might want to take a look at it.
