How to make widget layout choose screen/dialog

Question

I'm working on widgets for my application. There should be a few widgets which make the same thing and only difference is in their layout (theme/appearance)

I would make a dialog or screen where the user can choose the widget which he likes. I saw this in a lots of widgets when I was choosing them.

Is there a option to have only one main widget class with different layouts file depends on user choice? Or I have to make a special class for each one?

Eventually can I change layout color in dialog or screen when user picked up one of them for example?

I would like to show to the user that there are some other widgets in paid version of my app. So when user is in choosing widget screen/dialog he should see all my widgets and see that in paid version are some premium ones.

Thank you for your suggestion

Yes, it's possible. You can create one widget provider class and all the configuration will be done at the configuration activity, which can be called while creating a widget. Please take a look here. At this activity you can configure the widget and when it's done create preference file, which will contain all the settings for a newly created widget. You can name this file in a format myWidget<widgetID>. Later on, at your widget provider just read these files, taking ids from appWidgetIds and configure RemoteViews according to settings.
