问题 I'm creating an Android app in Android Studio. When I open the layout editor, I see that gray "popup window" on top of the layout, which says that it Couldn't resolve resource @style/Widget.Holo.Light.ActionMode.Inverse.

Has anyone else experienced this or came up with any solutions? 回答1: I found out what was up, when using the appcompat library. You can create your

问题 I want to use AppCompat library, however there is no Dialog theme, and there is no DialogWhenLarge theme which I can either extend or use. Is there a way I can extend the base theme and make it DialogWhenLarge, probably using folders and custom styling items. Thanks 回答1: Closing this ticket down.
