Kotlin TypeCasting

即使所有三个都产生相同的结果，后三个之间有什么区别？

val binding = DataBindingUtil.inflate<MyBinding>(LayoutInflater.from(view.context), R.layout.my_layout,
    null, false)

val binding: MyBinding = DataBindingUtil.inflate(LayoutInflater.from(view.context), R.layout.my_layout,
    null, false)

val binding = DataBindingUtil.inflate(LayoutInflater.from(view.context), R.layout.my_layout,
    null, false) as MyBinding

答案

val binding = DataBindingUtil.inflate（LayoutInflater.from（view.context），R.layout.my_layout，null，false）
