如何在kivy中创建一个文件选择器来支持不同语言(英语，希伯来语)的文件

from kivy.app import App

from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.popup import Popup
from kivy.lang import Builder
from kivy.properties import StringProperty

class FileChooser(BoxLayout):
    selected_file = StringProperty('')  # 用于存储选择的文件路径

    def __init__(self, **kwargs):
        super(FileChooser, self).__init__(**kwargs)
        self.orientation = 'vertical'

        # 创建文件选择器
        self.file_chooser = FileChooserListView()
        self.file_chooser.bind(selection=self.on_file_selected)

        # 创建标签显示选择的文件路径
        self.selected_file_label = Label(text=self.selected_file)

        # 创建按钮用于触发文件选择器
        self.select_button = Button(text='选择文件', on_release=self.open_file_chooser)

        # 将组件添加到布局中
        self.add_widget(self.select_button)
        self.add_widget(self.selected_file_label)

    def open_file_chooser(self, *args):
        # 创建弹出窗口
        content = BoxLayout(orientation='vertical')
        content.add_widget(self.file_chooser)
        popup = Popup(title='选择文件', content=content, size_hint=(0.9, 0.9))

        # 显示弹出窗口
        popup.open()

    def on_file_selected(self, instance, value):
        self.selected_file = value[0]  # 更新选择的文件路径
        self.selected_file_label.text = self.selected_file  # 更新标签显示

class FileChooserApp(App):
    def build(self):
        return FileChooser()

if __name__ == '__main__':
    FileChooserApp().run()

FileChooser:
    orientation: 'vertical'

    Button:
        text: _('Select File')

    Label:
        text: root.selected_file

from kivy.lang import Builder
from kivy.resources import resource_add_path

# 添加翻译文件路径
resource_add_path('path/to/translations')

# 加载翻译文件
Builder.load_file('filechooser.kv')
