Android 对话框的活动和片段需要不同的主题
我试图从一个片段（mainScreenFragment.java）创建一个对话框。有许多片段是从MainActivity调用的，因为我在这里使用的是选项卡视图，所以我在MainActivity中使用HOLO主题，但是当我尝试创建一个警报框时，片段中显示一个错误：“java.lang.IllegalStateException:此活动需要使用Theme.AppCompat主题（或子代）。” 请告诉我该怎么办 Manifest.xmlAndroid 对话框的活动和片段需要不同的主题,android,android-fragments,android-theme,android-styles,Android,Android Fragments,Android Theme,Android Styles,我试图从一个片段（mainScreenFragment.java）创建一个对话框。有许多片段是从MainActivity调用的，因为我在这里使用的是选项卡视图，所以我在MainActivity中使用HOLO主题，但是当我尝试创建一个警报框时，片段中显示一个错误：“java.lang.IllegalStateException:此活动需要使用Theme.AppCompat主题（或子代）。” 请告诉我该怎么办 Manifest.xml <?xml version="1.0" encoding=
