没懂你遇到的问题哈，不过 DataBinding 在 IDE 中确实时不时有奇怪的抽风，

建议是先跑下本示例项目，如果能跑起来，排除是 IDE 环境，

那么继续回到自己项目中，检查 AndroidManifest 中定义的包名，和 build.gradle 中定义的 ApplicationId 是否一致，

如果一致无误，clean 该项目然后重新 build 试试，

@KunMinX 我用了组件化，宿主包名确实和这个组件的包名不一样，这个有影响吗？（示例项目OK的）

KunMinX commented 1 year ago

检查一下宿主模块和组件模块的 build.gradle 中是否都有开启 databinding true，

如有，我暂时也没懂其他可能的缘由，可以咨询 chatgpt 看看

清理缓存就好了，关闭了，感谢大佬回复
