在 Kivy 应用程序界面中使用 Cyrillic 时出现 UnicodeDecodeError

  • 772

我正在尝试在界面中使用西里尔文，但应用程序无法启动。这是代码：

主文件

#  -*- coding: utf-8 -*-

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
import sys

sys.setdefaultencoding('utf-8')

class MainScreen(Screen):
    pass

class AnotherScreen(Screen):
    pass

class ScreenManagement(ScreenManager):
    pass

presentation = Builder.load_file("main.kv")

class MainApp(App):
    def build(self):
        return presentation

MainApp().run()

主文件

#  -*- coding: utf-8 -*-

ScreenManagement:
    MainScreen:
    AnotherScreen:

<MainScreen>:
    name: 'main'

    Button:
        on_release: app.root.current = 'other'
        text: 'Другой экран'
        font_size: 50

<AnotherScreen>:
    name: 'other'

    Button:
        on_release: app.root.current = 'main'
        text: 'back to the home screen'
        font_size: 50

当我运行android程序时，我得到：

[INFO ] [Kivy ] v1.9.2-dev0

在 Ubuntu 上一切都很好，没有问题。

有什么问题？

  1. 并且布局不需要指定编码。顺便说一下，你是如何在 PyDroid3 中安装 pygame 的？

    布局编码错误在 Windows 上很常见。Windows 上的 Python 3 默认以 win-1251 编码打开文件。为了让它在 utf-8 中打开，你必须强制 open(filename, encoding='utf-8') Kivy 打开而不指定编码，即 您自己需要打开一个带有编码的 kv 文件，将其读入一个变量并将其传递给 Builder。

    它是这样工作的：

    主文件

    #  -*- coding: utf-8 -*-

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen

class MainScreen(Screen):
    pass

class AnotherScreen(Screen):
    pass

class ScreenManagement(ScreenManager):
    pass

# ~presentation = Builder.load_file("main.kv")

with open("presentation.kv", encoding='utf8') as f:
    presentation = Builder.load_string(f.read())


class MainApp(App):
    def build(self):
        return presentation

MainApp().run()

    演示文稿.kv

    ScreenManagement:
    MainScreen:
    AnotherScreen:

<MainScreen>:
    name: 'main'

    Button:
        on_release: app.root.current = 'other'
        text: 'Другой экран'
        font_size: 50

<AnotherScreen>:
    name: 'other'

    Button:
        on_release: app.root.current = 'main'
        text: 'back to the home screen'
        font_size: 50
