I am currently creating a project using kivy but i am stuck on a certain area. I want to display data using list view format using for loop but when i am applying this condition inside the for loop to my function, the data i want to display on is not displaying.
example.py

kivy.require('1.9.2')

def on_leave(self):
self.background = (0, 154/255, 254/255, 1)
class AndroidApp(MDApp):

screen_manager = ScreenManager()
screen_manager.add_widget(Builder.load_file("home.kv"))

My UI
I want to solve my problem. Thank you for those who will answer my question.
CodePudding user response：
The main issue is that you are trying to use a OneLineListItem as a container. Try changing:
class ListView(OneLineListItem):
to something like:
class ListView(FloatLayout):
