近来用到一个工具类，网上找了一下没找到合适的，就改了一下。直接可用
importjava.util.ArrayList;
importjava.util.HashMap;
importorg.json.JSONArray;
importorg.json.JSONException;
importorg.json.JSONObject;
public classJsonMapHelper {
public static HashMap<String, Object> parseJSONObject(JSONObject jsonobj){
JSONArray a_name = jsonobj.names();
HashMap<String, Object> map =newHashMap<String, Object>();
if(a_name !=null) {
inti =0;
while(i < a_name.length()) {
String key;
try{
key = a_name.getString(i);
Object obj = jsonobj.get(key);
map.put(key,parseUnknowObjectToJson(obj));
}catch(JSONException e) {
e.printStackTrace();
}
i++;
}
}
returnmap;
}
public static HashMap<String, Object> parseJSONString(String json) {
JSONObject obj;
try{
obj =newJSONObject(json);
returnparseJSONObject(obj);
}catch(JSONException e) {
e.printStackTrace();
}
return new HashMap<String, Object>();
}
public static ArrayList<Object> parseJSONArray(JSONArray jsonarr) {
ArrayList<Object> list =newArrayList<Object>();
intlen = jsonarr.length();
for(inti =0; i < len; i++) {
Object o;
try{
o = jsonarr.get(i);
list.add(parseUnknowObjectToJson(o));
}catch(JSONException e) {
e.printStackTrace();
}
}
returnlist;
}
private static Object parseUnknowObjectToJson(Object o) {
if(oinstanceofJSONObject) {
returnparseJSONObject((JSONObject)o);
}
else if (oinstanceofJSONArray) {
returnparseJSONArray((JSONArray)o);
}
returno;
}
}
