Answer 1

解决方案

通过调用closeme()中的class Pops2()方法来关闭第二个Popup。有关详细信息，请参阅示例。

kv文件

1. 删除 Factory
的 import 语句
2. 将root.closepops2()替换为app.root.con.closeme()

Python文件

1. 在方法con中用self.con替换openpop()
2. 如果构造函数中super(...)和pass旁边没有其他代码，则删除所有构造函数。

示例

    def openme(self):
        Pops().open()

    def openpop(self):
        self.con = Pops2()
        self.con.content = Content()
        self.con.open()


class Pops(Popup):

    def closeme(self):
        self.dismiss()


class Pops2(Popup):

    def closeme(self):
