I have list of lessons. Users tap a lesson to open a dialog box.
In every (Android) dialog I want the user to be able to register for the lesson, and see the duration, in hours, of that lesson.
If the user has already registered I want to allow them to cancel their registration.
In my app, right now, a star symbol indicates a registered lesson.
- I don't know what buttons and icons to use in the dialog (a star, and an X for Cancel)?
- Do I add another button for closing the dialog?
- Or should a tap outside the dialog to close it?
