Android Studio Button not visible on Emulator
I just created in Android Studio some new Project. I chose the "Basic Acitivity" Template. Just to play around i changed the Text and run the app and everything works so far. When I add some more text, it also gets displayed in the Emulator. Also some CalendarView is displayed. But a normal Button is not visible in the Emulator. What am I doing wrong here?
