如何將給定的json轉換爲json數組

我將把json數據轉換成json數組，但是我得到的錯誤是： - 輸入org.json。 JSONObject不能轉換爲JSONArray。如何解決這個問題。 Click here view the json data 私人無效populateDashBoardReport（束束）{如何將給定的json轉換爲json數組

我添加了代碼，將值設置爲 –

更改爲向JsonObjectRequest

JsonObjectRequest jsonObjectRequest= new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() { 
      @Override 
      public void onResponse(JSONObject response) { 

       progressDialog.dismiss(); 

       mDashBoardVOsList = parseJsonResponse(response); 

       // set adapter for recycler view 
       mRecyclerViewAdapter = new MyRecyclerViewAdapter(mDashBoardVOsList); 
       mRecyclerView.setAdapter(mRecyclerViewAdapter); 

      } 
     }, new Response.ErrorListener() { 
      @Override 
      public void onErrorResponse(VolleyError error) { 

       progressDialog.dismiss(); 

       Log.e(TAG, "Error occured on DashBoard request :" + error.getMessage()); 

       Toast.makeText(getContext(), "Error loading DashBoard report :" + error.getMessage(), Toast.LENGTH_LONG).show(); 
      } 
     });

，改變JSON解析這個

private List parseJsonResponse(JSONObject response) { 

    List<DashBoardVO> dashboardVOsList = null; 

    if (response != null) { 
     JSONArray array=response.getJSONArray("lstGraph"); 
     dashboardVOsList = new ArrayList<>(); 

     for (int index = 0; index < array.length(); index++) { 

      DashBoardVO dashBoardVO = new DashBoardVO(); 

      try { 
       JSONObject jsonObject = array.getJSONObject(index); 

       dashBoardVO.setReceivable(jsonObject.getDouble("Receivable")); 
       dashBoardVO.setPayable(jsonObject.getDouble("Payable")); 

       dashboardVOsList.add(dashBoardVO); 

      } catch (JSONException e) { 
       Log.e(TAG, "Error occured while parsing JSON :" + e.getMessage()); 
      } 
     } 
    } 
    return dashboardVOsList; 
}

更新：

您可以使用Gson庫將JSON轉換爲Java Pojo類。

添加GSON依賴於你的build.gradle

compile 'com.google.code.gson:gson:2.8.1'

添加以下車型

轉換JSON到Java POJO使用下面的代碼

 private DashboardVOsList parseJsonResponse(JSONObject response) { 



    Gson gson =new Gson(); 
    DashboardVOsList dashboardVOsList= gson.fromJson(response.toString(),DashboardVOsList.class); 
return dashboardVOsList 


}

JSONObject jsonObject = response.getJSONObject（index）;我在這行索引中收到錯誤。錯誤是：Json對象不能應用於int –

我更新了代碼。請檢查 –

我還需要所有的字段不僅lstGraph。 –

org.json。 JSONObject的不能轉換爲JSONArray

你應該叫的JSONObject，而不是JSONArray。

不要

public void onResponse(JSONArray response) {

做

public void onResponse(JSONObject response) {

你JSON

{ 「應收款」：1967560.60，「應付款」：7508676.00」 oPendingFollowup 「：{」流失客戶tomers 「：5，」發票「：7，」 PerRec 「：509.62，」 InvValue 「：10027000.00}，」 oPDCReceive「：

做

private List parseJsonResponse(JSONObject response) 
{ 

    List<DashBoardVO> dashboardVOsList = null; 
    if (response != null) 
    { 
     dashboardVOsList = new ArrayList<>(); 
     DashBoardVO dashBoardVO = new DashBoardVO(); 

      for (int index = 0; index < response.length(); index++) 
       { 

       dashBoardVO.setReceivable(response.getDouble("Receivable")); 
       dashBoardVO.setPayable(response.getDouble("Payable")); 
       dashboardVOsList.add(dashBoardVO); 
       } 


    } 
     return dashboardVOsList; 
}

找到響應中的錯誤。錯誤是：無法應用mDashBoardVOsList = parseJsonResponse（response）; –

@RakeshKadadhi你的'response'是'JSONObject' –

我做了同樣的代碼，但它沒有來 –
