Question

我正在尝试在android中使用retrofit 2.1但是我只打印了7次作为响应的com.example.netapp.Model.PostUpdates@87943a3。我做错了什么？

的Json

[{
"id": "2",
"categories_id": "2",
"title": "समाज",
"featured_news": "0",
"cover_img": "50D5C03F4C476E718D615DEB3240CCB275E027A2.jpg",
"meta_desc": "एक चीन नीतिमा प्रतिवद्ध छौं: अर्थमन्त्री महरा",
"details": "उपप्रधान तथा अर्थमन्त्री कृष्णबहादुर महरासँग नेपालका लागि चीनका नवनियुक्त राजदुत यु होङले आज अर्थमन्त्रालयमा भेटबार्ता गरेकीछन्।",
"status": "1",
"postdate": "2016-11-18 16:45:16"
},
 ...]

主要活动类：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final TextView textView = (TextView) findViewById(R.id.textView);


    ApiService api_service = ApiService.retrofit.create(ApiService.class);
    final Call<List<PostUpdates>>  call = api_service.getUpdates("updates");

   call.enqueue(new Callback<List<PostUpdates>>() {
       @Override
       public void onResponse(Call<List<PostUpdates>> call, Response<List<PostUpdates>> response) {
           textView.setText(response.body().toString());
       }

       @Override
       public void onFailure(Call<List<PostUpdates>> call, Throwable t) {
            textView.setText(t.getMessage().toString());
       }
   });


}

ApiService接口

public interface ApiService{

    @GET("api/{param}")
    Call<List<PostUpdates>> getUpdates(@Path("param") String param);


    public final static Retrofit retrofit = new Retrofit.Builder()

哦！我得到它需要在响应体对象中使用getter方法来获取相应的数据。谢谢droidev

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final TextView textView = (TextView) findViewById(R.id.textView);


        ApiService api_service = ApiService.retrofit.create(ApiService.class);
        final Call<List<PostUpdates>>  call = api_service.getUpdates("updates");

       call.enqueue(new Callback<List<PostUpdates>>() {
           @Override
           public void onResponse(Call<List<PostUpdates>> call, Response<List<PostUpdates>> response) {

               StringBuffer sb = new StringBuffer();
               for(PostUpdates field : response.body()) {
                   sb.append( field.getTitle() + "\n");
               }

               Log.d(TAG, "onResponse: " + sb.toString());
               textView.setText(response.body().toString());

           }

           @Override
           public void onFailure(Call<List<PostUpdates>> call, Throwable t) {
                textView.setText(t.getMessage().toString());
           }
       });


    }
