问题 I am building a quiz game in Kivy, that has a TextInput option for users at the bottom of the screen. It's at the bottom because the clues for the answers are displayed at the top. The issue I am having is when I deploy my app to my phone, the Android on-screen keyboard pops up and blocks out nearly half my screen. I tried the softinput_mode in the Windows package, but this seems to push my entire screen up and so now, the top half of the screen is gone (and users can no longer see the clues)
