Kivy用按钮python代码更改屏幕

Question

I keep getting this error

TypeError: __init__() takes 1 positional argument but 2 were given

I tried everything to make it work but it still seems not to work. I'm trying to make an button where you click it if makes you go to a different screen but in python code.

self.add_widget(ImageButton(source=('Image.png'), size=(200,200), size_hint=(0.2, 0.2), on_press=ScreenFive, pos_hint={"x":0.3, "top":0.7}))

Can you help me? Thanks!

Answer 1

You sent ScreenFive as callback for on_press . the callback is called with the button instance so your error raise.

try this:

def callback(instance):
    sm.current = "screen_five"

... ... on_press=callback
