安卓工具类jsonString转hashmap

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;

}

}
