java-将JsonObject存储到HasMap中

概述我低于jsonResponse.在每个响应中,键和值都改变.我要存储计数&HashMap中的previousCountDay,键和值.Json回应：{"count":{"2018-03-2818":55,"2018-03-2819":48,"2018-03-2820":41,"2018-03-2821

我低于JsonResponse.

在每个响应中,键和值都改变.

我要存储计数& HashMap中的prevIoUsCountDay,键和值.

Json回应：

{    "count": {        "2018-03-28 18": 55,        "2018-03-28 19": 48,        "2018-03-28 20": 41,        "2018-03-28 21": 31,        "2018-03-28 22": 32,        "2018-03-28 23": 26,        "2018-03-29 00": 20,        "2018-03-29 01": 16,        "2018-03-29 02": 12,        "2018-03-29 03": 0    },    "prevIoUsCountDay": {        "2018-03-27 18": 40,        "2018-03-27 19": 59,        "2018-03-27 20": 53,        "2018-03-27 21": 48,        "2018-03-27 22": 36,        "2018-03-27 23": 40,        "2018-03-28 00": 37,        "2018-03-28 01": 14,        "2018-03-28 02": 29,        "2018-03-28 03": 1    },     "noOfIntervals": 10,    "range": [        "18",        "19",        "20",        "21",        "22",        "23",        "00",        "01",        "02",        "03"    ]}

通过使用GSON,我得到了JsON响应,但是我只存储范围,因为它即将出现在JsON数组中.按范围,我得到的是count& prevIoUsCountDay.

以下是我的活动课程：

 private voID JsonRequestOrderVeLocity(String dmhw) {    utils.showDialog();    String url = Constants.VELociTY_API;    Log.e("URL", "" + url);    JsonObjectRequest request = new JsonObjectRequest(url, null,            response -> {                Log.e("onResponse",""+response);                try {                    Gson gson = new Gson();                    Type ListType = new Typetoken<OrderVeLocityPojo>() {                    }.getType();                    orderVeLocityPojo = gson.fromJson(response.toString(), ListType);                    Log.e("SIZE",""+orderVeLocityPojo.getRange().size());                    JsONObject object = response.getJsONObject("count");                    Map<String, Integer> countMap = new HashMap<String, Integer>();                    //store keys and values in HashMap.                    for(int i=0;i<orderVeLocityPojo.getRange().size();i++){                       countMap.put( );                     }                } catch (Exception e) {                    Log.e("Exception",""+e);                    utils.hIDeDialog();                    e.printstacktrace();                }                utils.hIDeDialog();            }, error -> {        Log.e("error",""+error.getMessage());        utils.hIDeDialog();    });    request.setRetryPolicy(new DefaultRetryPolicy(            MY_SOCKET_TIMEOUT_MS,            DefaultRetryPolicy.DEFAulT_MAX_RETRIES,            DefaultRetryPolicy.DEFAulT_BACKOFF_MulT));    AppController.getInstance(this).addToRequestQueue(request);}

OrderVeLocityPojo Pojo类：

import java.util.List;import com.Google.gson.annotations.Expose;import com.Google.gson.annotations.Serializedname;public class OrderVeLocityPojo {    @Serializedname("noOfIntervals")    @Expose    private Integer noOfIntervals;    @Serializedname("range")    @Expose    private List<String> range = null;     public Integer getNoOfIntervals() {        return noOfIntervals;    }    public voID setNoOfIntervals(Integer noOfIntervals) {        this.noOfIntervals = noOfIntervals;    }    public List<String> getRange() {        return range;    }    public voID setRange(List<String> range) {        this.range = range;    }}

解决方法:

您还可以使用JsONObject的迭代键手动添加数据.

这是示例代码.

        HashMap<String, String> count = new HashMap<>();        HashMap<String, String> prevIoUsCountDay = new HashMap<>();        try {            JsONObject mJsonObjectMain = new JsONObject("your Json string");            JsONObject mJsonObjectCount = mJsonObjectMain.getJsONObject("count");            Iterator a = mJsonObjectCount.keys();            while (a.hasNext()) {                String key = (String) a.next();                // loop to get the dynamic key                String value = (String) mJsonObjectCount.get(key);                System.out.print("key : " + key);                System.out.println(" value :" + value);                count.put(key, value);            }            JsONObject mJsonObjectPrevIoUsCount = mJsonObjectMain.getJsONObject("prevIoUsCountDay");            //do same as above        } catch (JsONException e) {            e.printstacktrace();        }

最终代码：

HashMap<String, Integer> count = new HashMap<>();                     try {                        JsONObject object = response.getJsONObject("count");                        Iterator a = object.keys();                        while (a.hasNext()) {                            String key = (String) a.next();                            // loop to get the dynamic key                            Integer value = (Integer) object.get(key);                            Log.e("count : ","Keys :"+ key+"   Values :"+value);                            count.put(key, value);                        }                    } catch (JsONException e) {                        e.printstacktrace();                    }
