I had the same problem. Don’t know the cause, but I manage to get it working without changing “layout” file.
Looks like when using the emulator inside Android Studio with “Launch in the Running Devices tool window” enabled, the layout file is not properly loaded or its configurations are not rendered correctly. When this option is disabled everything magically works.
After running it perfectly outside tool window, I re-enabled the option and this time everything works inside Android Studio as it should in the first place.
So, after testing, if you want to run the emulator inside Android Studio you must follow these steps:
- Disable “Launch in the Running Devices tool window”
- Run the emulator
- Close the emulator
- Enable “Launch in the Running Devices tool window”
- Run the emulator again
(Every time that layout file changes, you’ll also have to follow these steps to apply the changes)
