Question

我用retrofit android用数据库服务器，问题是我在localhost上有一个数据库 https://i.stack.imgur.com/mdhOQ.png 我想创建一个数组，以便只在其中包含值哪个是数字8的值旁边这样arrayString包含makarona和asd而没有Other值但这里是打印makarona和asd和null 我想要一个具有数字8的相应名称的数组查看代码以查看arrayString并试图纠正我的代码

private void getAllMeal(final int id_) {
        api = HttpApi.getInstance();
        api.addHeader("Authorization", "MyT23");
        // Get iteme from index number .....
        getUsersCall = api.getService().getAllChatRooms4();
        ///----------------------------
        getUsersCall.enqueue(new retrofit.Callback<List<Users>>(){
            @Override
            public void onResponse(retrofit.Response<List<Users>> response, Retrofit retrofit) {
                user = response.body();

                String [] arrayString = new String[user.size()];
                int[] arrayInt = new int[user.size()];

                for(int i=0; i<response.body().size(); i++) {
                  arrayInt[i] = user.get(i).fk_chef;
                    if(Arrays.asList(arrayInt).contains(id_)){
                        arrayString[i] = user.get(i).name;
                    }
                  Toast.makeText(chef_hello.this,"results names  :"+arrayString[i],Toast.LENGTH_LONG).show();
                }

            }


            @Override
            public void onFailure(Throwable t) {
                //dialog2.dismiss();
                //Toast.makeText(chef_hello.this,"Error  Throwable xx :",Toast.LENGTH_LONG).show();
                // Toast.makeText(Regest_login.this, "XXX", Toast.LENGTH_LONG).show();
            }
        });
     }
