我是一個新手，所以我有一個愚蠢的問題。但這對我不起作用。
當我第一次單擊該程式時，它會打開一個帶有兩個按鈕的彈出按鈕。
我想為每個按鈕設定不同的文本顏色和不同的背景顏色。
我正在嘗試使用 KivyMD。因此，我很想對這兩個按鈕使用 MDRaisedButton。
我想要一個帶有藍色背景的黑色文本顏色的按鈕和另一個帶有白色和黑色背景的按鈕。
我非常感謝您的幫助。

uj5u.com熱心網友回復：
使用 . 設定背景顏色應該沒有任何問題md_bg_color。但是當您嘗試text_color特別為值設定# [0.0, 0.0, 0.0, 0.87]時可能會出現一些問題，[0.0, 0.0, 0.0, 1.0]并且[1.0, 1.0, 1.0, 1.0]（這看起來很尷尬！）。除了這些值，您可以自由設定任何有效的rgba格式顏色代碼。
因此，對于黑色文本，您可以將其設定為text_color: 0, 0, 0, 0.99（kvlang但在將來的版本中可能會改變；我在 1.0.0 中沒有找到任何內容）。或者為了保持向后兼容性，也許你可以設定theme_text_color: "Primary"等。
#實際上，在KivyMD v0.104.2的源代碼中，這些限制值有一個代碼塊。
