【问题描述】：

我的 jsonArray 数据如下：

  ["LeadId":4,
   "CoreLeadId":0,
   "CompanyId":7,
   "AccountNo":"5675",
   "ScheduleOn":"2015-05-11T00:00:00",
  "LeadId":7,
   "CoreLeadId":2,
   "CompanyId":8,
   "AccountNo":"sample string 4",
   "ScheduleOn":"2015-12-01T15:04:23.217"]   

我想按日期和时间（ScheduleOn）排序并放入列表视图。在我下方，我将我的代码片段发送到我设置适配器的位置。我们可以排序到 listItemService 中吗？请帮帮我。

   JSONArray jsonArray = dpsFunctionFlow.getAllServiceDetail("1");
   listItemService = new Gson().fromJson(jsonArray.toString(),
            new TypeToken<List<AppointmentInfoDto>>() 
            .getType());
    mAdapter = new AdapterAppointment(getActivity(), listItemService);
    listView.setAdapter(mAdapter);

【参考方案1】：

您应该能够使用 Collections.sort(...) 传入 Comparator 来比较 2 个 AppointmentInfoDto 对象。

Collections.sort(listItemService, new Comparator<AppointmentInfoDto>() 

    @Override public int compare(AppointmentInfoDto l, AppointmentInfoDto r) 
        // Compare l.ScheduleOn and r.ScheduleOn
    

【参考方案2】：

/// Sort JSON By any Key for date  
public static JSONArray sortJsonArray(JSONArray array,final String key,  final boolean  isCase)   
        List<JSONObject> jsonsList = new ArrayList<JSONObject>();  
        try   
            for (int i = 0; i < array.length(); i++)   
                jsonsList.add(array.getJSONObject(i));  
              
            Collections.sort(jsonsList, new Comparator<JSONObject>()   
                @Override  
                public int compare(JSONObject v_1, JSONObject v_2)   
                    String CompareString1 = "", CompareString2 = "";  
                    try   
                        CompareString1 = v_1.getString(key); //Key must be   present in JSON  
                        CompareString2 = v_2.getString(key); //Key must be present in JSON  
                     catch (JSONException ex)   
                       // Json Excpetion handling  
                      
                    return CompareString1.compareTo(CompareString2);  
                  
            );  
         catch (JSONException ex)   
               // Json Excpetion handling  
          
        return new JSONArray(jsonsList);  
      

// _Sort JSON for any String Key value.........  
public static JSONArray sortJsonArray(JSONArray array,final String key,   final boolean  isCase)   
        List<JSONObject> jsonsList = new ArrayList<JSONObject>();  
        try   
            for (int i = 0; i < array.length(); i++)   
                jsonsList.add(array.getJSONObject(i));  
              
            Collections.sort(jsonsList, new Comparator<JSONObject>()   
                @Override  
                public int compare(JSONObject v_1, JSONObject v_2)   
                    String CompareString1 = "", CompareString2 = "";  
                    try     
                        CompareString1 = v_1.getString(key); //Key must be present in JSON  
                        CompareString2 = v_2.getString(key); //Key must be present in JSON  
                     catch (JSONException ex)   
                       // Json Excpetion handling  
                      
                    return isCase ? CompareString1.compareTo(CompareString2) : CompareString1.compareToIgnoreCase(CompareString2);
                  
            );  
         catch (JSONException ex)   
             // Json Excpetion handling  
          
        return new JSONArray(jsonsList);
