Kivy 应用程序显示在屏幕左下角

Question

我的 Kivy 应用程序显示在手机屏幕的左下角（您可以在共享屏幕截图中看到）。但我想将其设为全屏。我在“buildozer.spec”文件中将“全屏”值设置为 1。但没有任何改变.这是我的代码：

from kivy.app import App

rpart = False

och = False
vch = False
rch = False

ofin = False

rfin = False

fin = True

snd_part = SoundLoader.load("part.wav")
music = SoundLoader.load("music.wav")
music.play()

win = MainApp()

win.run()

这里你可以看到截图。这就是它在我手机上的显示方式：

Answer 1

将

Window.size = (320,640)

行替换为：

from kivy.utils import platform

if platform not in ["android", "ios"]:
    Window.size = (320,640)

旁注，您可能想要将使用 320x640 像素数或至少小于它的属性更改为

size_hint=(1,1)

之类的内容。对于大多数人来说这个答案可能不清楚，但这是我能做的最好的事情
