Answer 1

将JSON数组转换为POJO类，然后使用改造网络调用来调用api。

Answer 2

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);
                }
            }
