在 kivymd 中更改弹出窗口 window 上的 MDRaisedButton 的文本颜色?

change text color of a MDRaisedButton on a popup window in kivymd?

我是新手,所以我有一个愚蠢的问题。但它对我不起作用。

当我第一次点击这个程序时,它会打开一个带有两个按钮的弹出按钮。

我想为每个按钮设置不同的文本颜色和不同的背景颜色。

我正在尝试使用 KivyMD。因此,我很乐意为这两个按钮使用 MDRaidButton。

我想要一个带有黑色文本颜色和蓝色背景的按钮,另一个按钮带有白色和黑色背景。

非常感谢你的帮助。

使用 md_bg_color 设置背景颜色应该没有任何问题。但是当您尝试设置 text_color 时可能会出现一些问题,尤其是对于值 # [0.0, 0.0, 0.0, 0.87], [0.0, 0.0, 0.0, 1.0][1.0, 1.0, 1.0, 1.0] (这看起来很尴尬!)。除了这些值,您可以自由设置 rgba 格式的任何有效颜色代码。

因此,对于黑色文本,您可以像 kvlang 中的 text_color: 0, 0, 0, 0.99 那样设置它(但这可能会在未来的版本中改变;我在 1.0.0 中没有找到任何内容)。或者为了保持向后兼容性,也许您可​​以设置 theme_text_color: "Primary"


#实际上在 KivyMD v0.104.2 的 source code 中有一个 code-block 用于那些限制值。
