kivy Label标记文本

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder

# 注意只有text的color是小写 canvas中的Color是大写要加括号
# canvas.before在最下面
# 要激活标记文本 必须加markup:True
Builder.load_string("""
<BoxLayoutWidget>:
    orientation:'vertical'

    Label:
        text:' I Link [i]China[/i],very Link '
        color:.9,.2,.1,1
        markup:True

    Label:
        text:'[b]to[/b][sup]2[/sup] be[sub]2[/sub] number one'

        markup:True
        canvas.before:
            Color:
                rgba:(1,1,1,1)
