retrofit has nothing to do with JSON. It only makes network calls — Vladyslav Matviienko, Oct 31 '18 at 05:20
You can make model class and use that model class as response and from that response you can get that variable — DB377, Oct 31 '18 at 05:25

Convert JSON Array into POJO classes and then call api using retrofit network call.

Use this link

copy your json and it gives you two model class you should put the parent class which contains error , message and districts as your output in your request. something like this

@GET("your_url")
Call<ModelExample> nameOfMethod();

And then you have list of districts. you can access to the items and districtID and name I hope it helps you :)

      for onResponse:
   --------------------------
        Call<ModalClass> daoCall = api.getconnectdata();
          modelclass.enqueue(new Callback<ModalClass>() {
           @Override
            public void onResponse(Call<ModalClass> call, Response<ModalClass> 
            response) {
                if(response.isSuccessful()){
                    modelclass= response.body();
             List<Districts>  list = modelclass.getAddData().getData();
             adapter = new CustomListAdapter(getApplicationContext(),list);
               listView.setAdapter(adapter);
                }
            }
