我有一个活动A，视图中有一个按钮B.如果有人按下B键，那么我想要一个弹出窗口，该弹出窗口可以占据屏幕的一部分，从而使A在该区域不可见，但A的其余部分可见但不起作用.我该如何实现?

I have an Activity A, and there is a button B in the view. If somebody presses B then I want a pop-up which can take some part of screen making the A invisible in that area but rest of A is visible but not active. How can I achieve this?

推荐答案

如果要使用活动"而不是对话框"来执行此操作，则可以通过在清单中将活动的主题设置为android:theme="@android:style/Theme.Dialog"来执行此操作-使活动看起来像一个对话框(浮动在其下面的任何内容之上).

If you want to do this using an Activity instead of a Dialog, you can do this by setting the activity's theme to android:theme="@android:style/Theme.Dialog" in the manifest - this will make the activity appear like a dialog (floating on top of whatever was underneath it).
