问题描述
我正在尝试在EmployeeScreen类内部使用kivy scrollview.它不会滚动！?我究竟做错了什么?希望这不是重复的，请帮忙.我转到了此链接 Kivy ScrollView-不滚动.这似乎是关于kivy scrollview不滚动的唯一问题.这不能解决我的问题.

推荐答案
我试图在.kv文件中使用GridLayout，错了，我不得不创建一个类并覆盖其 init .
I was trying to use GridLayout in my .kv file, wrong, I had to create a class and override its init.
class MyLayout(GridLayout):
def __init__(self,**kwargs):
super(MyLayout,self).__init__(**kwargs)
self.size_hint_y = (None)
self.bind(minimum_height = self.setter('height'))
然后将类放在GridLayout所在的.kv文件中.
then I placed the class in the .kv file where GridLayout was.
