- 基維:1.11.1
- Kivy安裝方式:pip
FileChooser 在滾動文件列表時會重疊文本.看起來第一個內容保持不變，滾動數據的內容顯示在第一個內容的頂部.
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()

推薦答案
對于面臨同樣問題的人，我通過將 FileChooser 替換為 Plyer 的原生文件選擇器來解決.Github 上的討論可以在這里找到
For people who are facing the same issue, I resolved by replacing FileChooser with Plyer's native filechooser. Disussion on Github can be found here
