このエラーを修正する方法java.lang.IllegalStateException：BEGIN_ARRAYが必要ですが、行1の列2のパスでBEGIN_OBJECTが発生しました$

Question

私はAndroidを使用して安らかなクライアントを実装しています。 API URL、トークンなどがあります。私はこのアプリケーションをRetrofit 2ライブラリを使用して実装していますが、すべて正しいです。しかし、JSON値は正しく表示されません。私はこの問題を解決するためにいくつかの方法を試しましたが、これに対して正しい解決策を見つけることはできません。

これは私のコードです：

JSON文字列

{"deposits":[{"id":806638,"amount":100,"status":"Canceled","reason":null},{"id":814436,"amount":1,"status":"Approved","reason":null},{"id":814452,"amount":1,"status":"Approved","reason":null},{"id":814505,"amount":1,"status":"Approved","reason":null}]} 

主な活動

void getRetrofitArray() { 

    final String API_BASE_URL = "https://www.example.com/"; 
    final String credentials = "Bearer dfdfdfdlcdvksbdjsbdlvffdfddfdfdfjloiulfjuktj92p0JTFwJuFHlObIlWn8feQ_WA"; 
      OkHttpClient okHttpClient = new OkHttpClient.Builder() 
      .addInterceptor(new okhttp3.Interceptor() { 
       @Override 
       public Response intercept(okhttp3.Interceptor.Chain chain) throws IOException { 

        Request request = chain.request().newBuilder() 
          .addHeader("Authorization", credentials) 
          .addHeader("Accept", "application/json").build(); 

        return chain.proceed(request); 

       } 
      }).addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)) 
      .readTimeout(60, TimeUnit.SECONDS) 
      .connectTimeout(60, TimeUnit.SECONDS) 
      .build(); 

    Retrofit retrofit = new Retrofit.Builder() 
      .baseUrl(API_BASE_URL) 
      .client(okHttpClient) 
      .addConverterFactory(GsonConverterFactory.create()) 
      .build(); 


    LoginApi service = retrofit.create(LoginApi.class); 



    Call <List <Users>>call = service.getDeposits(); 
    Log.d("onResponse", "There is an xlllllllllllllllllllllkkkkkkklll"); 
    call.enqueue(new Callback<List<Users>>(){ 
     @Override 
     public void onResponse(Call<List<Users>>call, retrofit2.Response<List<Users>>response) { 

      try { 

       // Users UserData = response.body(); 
       List <Users> UserData =response.body(); 

       //String jsonString= response.body().toString(); 
       // Type listType = new TypeToken<List<Users>>(){}.getType(); 

             for (int i = 0; i < UserData.size(); i++) { 

        text_marks_1.setText("StudentMarks : " +UserData.get(i).getDeposits()); 


        // else if (i == 2) { 
         //text_id_2.setText("StudentId : " + UserData.get(i).getName()); 
        // 
       } 
      } catch (Exception e) { 
       Log.d("onResponse", "There is an error"); 
       e.printStackTrace(); 
      } 
     } 

     @Override 
     public void onFailure(Call<List<Users>>call, Throwable t) { 
      Log.d("onResponse", "There is an error"); 
      t.printStackTrace(); 
     }

私はあなたのAPIを考えますインターフェース・クラスは、次のようになります。

@GET("api/deposits") 
Call<User> getDeposits(); 

とあなたの活動に：

Call<User> call = service.getDeposits(); 
call.enqueue(new Callback<User>(){ 
    @Override 
    public void onResponse(Call<User>call, retrofit2.Response<User>response) { 

      List<Deposit> = response.getDeposits(); 

      } 

    }
