Android：Unable to collect necessary methods for class java.lang.NoSuchMethodException异常解决办法

这个问题困扰了我许久，是在使用RecyclerView的适配器时抛出的异常，不知问题出自何处的我更惊叹的是网上竟找不到任何类似问题的解决办法，最终也只是在stackoverflow找到一个基本相同的问题，但是也没有人回答，不过最后还是解决了，在这里分享一下解决的办法

报错信息如下

指向onCreateViewHolder中的这一行

View itemView = View.inflate(mContext,R.layout.message_view, null);

程序会报异常，但却可以运行

解决方案一

修改build.gradle中的targetSdkVersion为28

targetSdkVersion 28

解决方案二

添加依赖

def core_version = "1.3.2"

用Java的话还需要

//Java
implementation "androidx.core:core:$core_version"

用Kotlin加这个

// Kotlin
implementation "androidx.core:core-ktx:$core_version"

最后同步依赖重新启动项目就可以了
