I am trying to put a switch widget in my activity in IntelliJ. When I do this, the designer crashes with a NullPointException exception inside android.widget.Switch.jumpDrawablesToCurrentState and a long stack trace.
Element added with android: id = "@ + id / switch", which throws a compiler error: invalid character: 'switch'
I need to change the name to another, but "switch." It is strange to see that the system adds an invalid name, but normal, I could live with it.
But the visual constructor is still useless when the switch is in the layout. The only thing I can find on Google is a bug tracker entry describing this. But there is no solution. What is going on there? Does anyone know a solution?
Edit I am adding a stack trace:

This is displayed in the designer view instead of activity after adding the switch.
