기존 Retrofit Callback 계속 붙이면?

 

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val api = RetrofitInstance.getInstance().create(MyApi::class.java)

        api.getPost().enqueue(object :Callback<Post> {
            override fun onResponse(call: Call<Post>, response: Response<Post>) {
                Thread.sleep(1000)
                Log.d("MAIN", response.body().toString())
            }

            override fun onFailure(call: Call<Post>, t: Throwable) {
                Log.d("MAIN", t.toString())
            }
        })

        api.getPost2(2).enqueue(object :Callback<Post> {
            override fun onResponse(call: Call<Post>, response: Response<Post>) {
                Log.d("MAIN2", response.body().toString())
            }

            override fun onFailure(call: Call<Post>, t: Throwable) {
                Log.d("MAIN2", t.toString())
            }
        })

        api.getPost2(3).enqueue(object :Callback<Post> {
            override fun onResponse(call: Call<Post>, response: Response<Post>) {
                Log.d("MAIN3", response.body().toString())
            }

            override fun onFailure(call: Call<Post>, t: Throwable) {
                Log.d("MAIN3", t.toString())
            }
        })


    }
