问题描述

我有一个使用 Theme.Dialog 样式的活动，因此它是另一个活动的浮动窗口.但是，当我在对话框窗口外(在后台活动上)单击时，对话框将关闭.我怎样才能阻止这种行为?

I have an activity that is using the Theme.Dialog style such that it is a floating window over another activity. However, when I click outside the dialog window (on the background activity), the dialog closes. How can I stop this behaviour?

推荐答案

这可以帮助您.这是一种处理触摸外部事件的方法:

This could help you. It is a way to handle the touch outside event:

如何在窗口外触摸时取消以活动为主题的对话框?

通过捕捉事件而不做任何事情，我认为您可以防止关闭.但奇怪的是，您的活动对话框的默认行为应该是不在您触摸外部时自行关闭.

By catching the event and doing nothing, I think you can prevent the closing. But what is strange though, is that the default behavior of your activity dialog should be not to close itself when you touch outside.
