When you long press on an email in Gmail application the dialog box is shown. I'm wondering is it just a dialog or an activity represented as dialog? Thank you.

推荐答案

也许这应该是一个对话框键，当您选择/单击它可以打开一个项目活动基于命令的类型。然而，一个 Activty 可以显示为对话框但这里的对话框中的项目都涉及到的范围内同样activty therfore它不可能是一个新activty这里。

Probably it should be a Dialog and when you select/click the item it may be open an Activity based on the type of commands. However an Activty can be displayed as a Dialog but here as the items in the dialog are related to the context of the same activty therfore it can't be a new activty here.
