Generic class input param type miss match

Question

Always get an Error type mismatch, when input param for getObjectSingle. how do I fix with my generic wrapper class?

Answer 1

You need the class not the instance, but you must create an instance of the class to get class itself, try this:

val wrapper = Wrapper<String>()

Rx2AndroidNetworking.post(someUrl)
        .build()
        .getObjectSingle(wrapper.javaClass)

OR

val wrapper = Wrapper<String>()

Rx2AndroidNetworking.post(someUrl)
        .build()
        .getObjectSingle(wrapper::class.java)

OR

val wrapper = Wrapper<String>()

val s: Class<Wrapper<String>> = wrapper.javaClass

Rx2AndroidNetworking.post(someUrl)
        .build()
        .getObjectSingle(s)
