Ich schreibe App für Android mit Xamarin.Recycler View (Xamarin Android)
Ich versuche Recycler zu sehen.
Hier ist meine json: http://pastebin.com/rL214a2T
Ich habe Klassen wie folgt aus:
public class Billing
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_1 { get; set; }
public string address_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postcode { get; set; }
public string country { get; set; }
public string email { get; set; }
public string phone { get; set; }
}
public class Shipping
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_1 { get; set; }
public string address_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postcode { get; set; }
public string country { get; set; }
}
public class Result
{
public int id { get; set; }
public int parent_id { get; set; }
public string status { get; set; }
public string order_key { get; set; }
public int number { get; set; }
public string currency { get; set; }
public string version { get; set; }
public bool prices_include_tax { get; set; }
public string date_created { get; set; }
public string date_modified { get; set; }
public int customer_id { get; set; }
public string discount_total { get; set; }
public string discount_tax { get; set; }
public string shipping_total { get; set; }
public string shipping_tax { get; set; }
public string cart_tax { get; set; }
public string total { get; set; }
public string total_tax { get; set; }
//public List<Billing> billing { get; set; }
public Billing billing { get; set; }
public Shipping shipping { get; set; }
public string payment_method { get; set; }
public string payment_method_title { get; set; }
public string transaction_id { get; set; }
public string customer_ip_address { get; set; }
public string customer_user_agent { get; set; }
public string created_via { get; set; }
public string customer_note { get; set; }
public string date_completed { get; set; }
public string date_paid { get; set; }
public string cart_hash { get; set; }
public List<object> line_items { get; set; }
public List<object> tax_lines { get; set; }
public List<object> shipping_lines { get; set; }
public List<object> fee_lines { get; set; }
public List<object> coupon_lines { get; set; }
public List<object> refunds { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
ich so schreibe Klasse:
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
using ModernHttpClient;
using Newtonsoft.Json;
namespace StarWars.Api.Repository
{
public class MoviesRepository
{
public async Task<RootObject> GetAllFilms()
{
var httpClient = GetHttpClient();
var response = await httpClient.GetAsync(ServiceEndPoints.StartWarsApiBaseUri).ConfigureAwait(false);
if (response.IsSuccessStatusCode)
{
var content = response.Content;
string jsonString = await content.ReadAsStringAsync().ConfigureAwait(false);
return JsonConvert.DeserializeObject<RootObject>(jsonString);
}
return new RootObject();
}
private HttpClient GetHttpClient()
{
var httpClient = new HttpClient(new NativeMessageHandler())
{
BaseAddress = new Uri(ServiceEndPoints.StartWarsApiBaseUri)
};
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
return httpClient;
}
}
public class ServiceEndPoints
{
public static readonly string StartWarsApiBaseUri = "http://api.simplegames.com.ua/index.php/?wc_orders=processing_orders";
// public static readonly string GetFilmsUri = "films";
}
}
Aber wenn ich versuche App zu starten ich diese haben Fehler
Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'StarWars.Api.Repository.RootObject' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Wie ich verstanden habe muss ich setzen
Wie kann ich es beheben?
UPDATE
Mit ReSharper I Remake Code wie diese
public async Task<List<RootObject>> GetAllFilms()
{
var httpClient = GetHttpClient();
var response = await httpClient.GetAsync(ServiceEndPoints.StartWarsApiBaseUri).ConfigureAwait(false);
if (response.IsSuccessStatusCode)
{
var content = response.Content;
string jsonString = await content.ReadAsStringAsync().ConfigureAwait(false);
return JsonConvert.DeserializeObject<List<RootObject>>(jsonString);
}
return new List<RootObject>();
}
private HttpClient GetHttpClient()
{
var httpClient = new HttpClient(new NativeMessageHandler())
{
BaseAddress = new Uri(ServiceEndPoints.StartWarsApiBaseUri)
};
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
return httpClient;
}
}
public class ServiceEndPoints
{
public static readonly string StartWarsApiBaseUri = "http://api.simplegames.com.ua/index.php/?wc_orders=processing_orders";
// public static readonly string GetFilmsUri = "films";
}
}
Aber ich habe Fehler in meinem MainActivity in dieser Reihe var moviesAdapter = new MovieAdapter(films.results)
Hier ist Fehler
Fehler CS1061 'List' enthält keine Definition für 'Ergebnisse' und keine Erweiterungsmethode 'results', die ein erstes Argument vom Typ 'List' akzeptiert (fehlt eine using-Direktive oder eine Assemblyreferenz?)
Können Sie auch Ihre JSON teilen? –
