Kotlin-Not enough information to infer parameter T in fun<T:View> findViewById(id: Int): T!

代码改变世界

错误：

Type inference failed : Not enough information to infer parameter T in fun<T:View> findViewById(id: Int): T! Please specify it explicitly.

解决：

holder.btnInstall = convertView.findViewById(R.id.btn_install) as Button  

改为

holder.btnInstall = convertView.findViewById<Button>(R.id.btn_install)
