我正在写一个Android应用程序，我想放置一个对话框或视图在主屏幕，以便用户可以在不跳进我的全部应用程序中输入文本。我似乎无法得到这个工作。如果我present一个对话框（即使是在一个透明的活动），我的应用程序启动。

I'm writing an Android application and I would like to place a dialog or view over the home screen so that a user can enter text without jumping into my full application. I can't seem to get this to work. If I present a dialog (even in a transparent activity), my application launches.

如果你不知道我在说什么，看看Facebook的部件。我想复制一个类似的行为上的点击什么是您的想法？框。

If you don't know what I'm talking about, take a look at the Facebook widget. I want to replicate a similar behavior to the clicking on the "What's on your mind?" box.

感谢提前任何帮助！
