解决三星手机post请求时参数包括集合，封装成JSONObject，结果不是数组而是数组的地址问题

下面是用volley进行的post请求
HashMap<String, Object> params = new HashMap<>();
//门店id
params.put("id",storeId);
//商场id
params.put("mallId",market_id);
//品牌id
params.put("brandId",brand_id);
JSONObject json = new JSONObject(params);
然后调用
VolleyRequest.jsonRequest(this, Request.Method.POST, new Constant(mContext).Store_Save, new Constant(mContext).HGJ_TAG, json, new VolleyInterface(ChangeBaseInfoActivity.this, VolleyInterface.mListener, VolleyInterface.mErrorListener) {}
这样会请求失败，找原因发现如下：
JSONObject json = new JSONObject(params);
是它将参数封装为JSONObject的结果有问题如下：
{"id":10730,"scale":"MIDDLE_SCALE","phone":"","floorIds":"[I@42ddc4e8","categoryIds":"[I@42ddc8f0","mallId":5,"houseNumber":"","brandId":9017}

而我们要的JSONObject的样式应该是下面这样：

{"id":10737,"scale":"MIDDLE_SCALE","phone":"","floorIds":[5,6,7,2,3,4,8],"categoryIds":[9,11],"mallId":3,"houseNumber":"","brandId":9000}
最后找到解决方法，我们用的Jackon解析框架
String s = JsonUtils.obj2Json(params);
JSONObject json = null;
try {
json = new JSONObject(s);
} catch (JSONException e) {
e.printStackTrace();
}

String s = JsonUtils.obj2Json(params);
JSONObject json = null;
try {
json = new JSONObject(s);
Log.i("--json---",json.toString());
} catch (JSONException e) {
e.printStackTrace();
}
