Kivy//When opening the VirtualKeyboard on android, the entire contents of the window is shifted up. How can you fix it?

Question

Kivy

Can someone tell me how to implement in kivy so that when the keyboard is opened:

1. It does not overlap the content when the input is focused, but makes it above the keyboard itself.
2. She did not push the topbar (toolbar) out of the screen.
softinput can only do 1 item. We need a principle of action like that of instant messengers, when messages sort of go behind the topbar, even when the keyboard is opened. That is, the top bar is always on the same position.
