Kivy Filechooser 在滚动屏幕上重叠文本

FileChooser overlaps text on scrolling through files list. Looks like the 1st content stays and on scroll the content of scrolled data is getting displayed on top of 1st content.

from kivy.app import App
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.screenmanager import Screen, ScreenManager
from kivy.uix.popup import Popup
from kivy.properties import ObjectProperty, BoundedNumericProperty, StringProperty
from kivy.lang import Builder

class FirstWindow(Screen):
    def show_load(self):
        content = LoadDialog(load=self.load, cancel=self.dismiss_popup)
        self._popup = Popup(title="Load file", content=content,
                            size_hint=(0.9, 0.9))
        self._popup.open()

    def dismiss_popup(self):
        self._popup.dismiss()

    def cancel(self):
        pass

    def load(path, selection):
        print(path, selection)

class LoadDialog(FloatLayout):
    load = ObjectProperty(None)
    cancel = ObjectProperty(None)

class EditorApp(App):
    def build(self):
        kv = Builder.load_file("editor.kv")
        self.screen_manager = ScreenManager()

        screen = FirstWindow(name="first")
        self.screen_manager.add_widget(screen)
        self.screen_manager.current = "first"

        return self.screen_manager

if __name__ == "__main__":
    editor_app = EditorApp()
    editor_app.run()

KV 文件

<FirstWindow>:
  BoxLayout:
    orientation: "vertical"
    Button:
      text: "Select Folder"
      on_release: root.show_load()

<LoadDialog>:
  BoxLayout:
    size: root.size
    pos: root.pos
    orientation: "vertical"
    FileChooserListView:
      id: filechooser

    BoxLayout:
      size_hint_y: None
      height: 30
      Button:
        text: "Cancel"
        on_release: root.cancel()

      Button:
        text: "Load"
        on_release: root.load(filechooser.path, filechooser.selection)

解决方案

对于面临同样问题的人，我通过将 FileChooser 替换为 Plyer 的原生文件选择器来解决.Github 上的讨论可以在这里找到
