Kivy 无法使用 ButtonBehavior 向按钮添加文本
Kivy unable to add text to button using ButtonBehavior
我想在圆形图片的右侧添加文字。我被告知要使用标签来执行此操作，但我无法弄清楚如何实际执行此操作。它必须是动态的，所以如果您必须使用 KV 语言执行此操作，您能告诉我即使在 KV 文件中制作按钮时如何保持按钮动态。如果可能的话，我想将其保留在 Python 文件中，但如果 KV 方式更好，那就这样吧。

ButtonBehaviour 不支持文本。试试这个：
button = Button()
button.size_hint=(None,None)
button.size=(200,200)
button.text = "some text"
button.background_normal = 'Trifecta.png';
我自己找到了答案，使用ButtonBehavior时，只能在KV语言的按钮内放置一个标签。然后你可以只使用 Factory 从 python 文件访问按钮。 ImageButton class 中的 "text = StringProperty()" 是必需的，因为存在某种错误导致生成的第一个按钮没有文本。
