要修改说明：
-
移除手动处理的代码：删除了大量手动创建
SpannableStringBuilder、ForegroundColorSpan、ClickableSpan的代码 -
使用 SpannableStringInstance：
- 导入了
SpannableStringInstance类 - 使用
SpannableStringInstance.create()创建实例 - 使用
setClickableSpan()方法一次性设置文本颜色和点击事件 - 使用
applyTo()方法将样式应用到 TextView
- 导入了
-
代码简化：
- 原本需要手动计算文本位置、设置颜色、设置点击事件的复杂逻辑，现在只需要一行方法调用
- 代码更加清晰易读，维护性更好
-
功能保持不变：所有原有功能都得到保留，包括点击事件处理和 CheckBox 状态切换
这样重构后的代码更加简洁，也更容易维护和扩展
