已解决：只需将我的 drawable ic_plus_white.xml 从 drawable-v-24 文件夹移动到 drawable 文件夹。解决了问题！
请确保您的应用或 activity 主题继承了以下主题之一：
- Theme.MaterialComponents
- Theme.MaterialComponents.NoActionBar
- Theme.MaterialComponents.浅色
- Theme.MaterialComponents.Light.NoActionBar
- Theme.MaterialComponents.Light.DarkActionBar
- Theme.MaterialComponents.DayNight
- Theme.MaterialComponents.DayNight.NoActionBar
- Theme.MaterialComponents.DayNight.DarkActionBar
您的 drawable/ic_plus_white 似乎不是有效的可绘制对象。也请验证它的内容。
您遇到的问题在启动 activity XML 的第 26 行。如果您能向我们展示该文件，我们可能会提供帮助。
