python - 如何在 python 中使用 id 的 kivy？

问题描述

由于某种原因，此代码无法正常工作。我正在尝试使函数“ definir() ”来查找TextInput (id=roupa)但没有按预期工作。

def nomeapp(self):
    close_button = MDFlatButton(text="Cancelar", on_release=self.close_dialog_nomeapp)
    confirme_button = MDFlatButton(text="Definir",on_release=self.definir)
    self.nomeappp = MDDialog(title="Definir Nome",
                            type="custom",
                            content_cls=TextInput(text="This is a test",id="roupa"),
                            text="Aqui vai entrar um textinput",
                            size_hint=(0.7, 1.), buttons=[close_button, confirme_button])
    self.nomeappp.open()


def definir(self,obj):
    print(self.ids.roupa.text)
    self.nomeappp.dismiss()


def close_dialog_nomeapp(self, obj):
    self.nomeappp.dismiss()

非常感谢某人为解决上述问题提供的一些指导/帮助。提前致谢。
