控件id有些多就打算用viewBinding,配置好后原本打算是在MainActivity的onCreate外用的，但不起作用，以为有另外的写法，没想到在onCreate中试也不起作用。我在另外的项目使用正常的啊，是什么原因导致冲突了吗？gradle版本8.0。
viewBinding我有试过删除后退出项目，重新进入再重新装，问题依旧。
之前以为是AndroidManifest的android：name指定了全局函数的原因，尝试删了依旧。
应该发现主要的原因了，与MainActivity对应的activity_main.xml里的id就能直接用，另外的xml
就无法使用，这个要怎么解决.

mainMativity,到了这里使用binding.buttoin1就爆红了
