我如何将ArrayList发送给Php并在PHP SCripts中使用volley接受它？有没有解决方案而无需转换为Json

Question

@Override
protected Map<String, String> getParams() throws AuthFailureError {
    Map<String, ArrayList<String>> map = new HashMap<String,ArrayList<String>>();
                      map.put("title",interest);
              return map;
    }
};

I am trying this way but I know this is possible only for string not arraylist

Answer 1

String key = "phpArray[]";

JSONArray jsonArray = new JSONArray();
jsonArray.put(1);
jsonArray.put(2.3f);
jsonArray.put("Four");
jsonArray.put(true);

map.put(key, jsonArray.toString());
