将JsonObject转换成HashMap

1.工具类：

Utils.class:

(1)简单的键值对map

public class Utils {public static String getRaw(Context context, int RawId) {try {InputStream is = context.getResources().openRawResource(RawId);BufferedReader reader = new BufferedReader(new InputStreamReader(is));// StringBuffer线程安全；StringBuilder线程不安全StringBuffer sb = new StringBuffer();for (String str = null; (str = reader.readLine()) != null;) {sb.append(str);}return sb.toString();} catch (IOException e) {e.printStackTrace();}return null;}public static String getAsset(Context context, String fileName) {try {InputStream is = context.getResources().getAssets().open(fileName);// StringBuffer线程安全；StringBuilder线程不安全BufferedReader reader = new BufferedReader(new InputStreamReader(is));StringBuffer sb = new StringBuffer();for (String str = null; (str = reader.readLine()) != null;)  {sb.append(str);}return sb.toString();} catch (IOException e) {e.printStackTrace();}return null;}public static void JsonObject2HashMap(JSONObject jo, List<Map<?, ?>> rstList) {for (Iterator<String> keys = jo.keys(); keys.hasNext();) {try {String key1 = keys.next();System.out.println("key1---" + key1 + "------" + jo.get(key1)+ (jo.get(key1) instanceof JSONObject) + jo.get(key1)+ (jo.get(key1) instanceof JSONArray));if (jo.get(key1) instanceof JSONObject) {JsonObject2HashMap((JSONObject) jo.get(key1), rstList);continue;}if (jo.get(key1) instanceof JSONArray) {JsonArray2HashMap((JSONArray) jo.get(key1), rstList);continue;}System.out.println("key1:" + key1 + "----------jo.get(key1):"+ jo.get(key1));json2HashMap(key1, jo.get(key1), rstList);} catch (JSONException e) {e.printStackTrace();}}}public static void JsonArray2HashMap(JSONArray joArr,List<Map<?, ?>> rstList) {for (int i = 0; i < joArr.length(); i++) {try {if (joArr.get(i) instanceof JSONObject) {JsonObject2HashMap((JSONObject) joArr.get(i), rstList);continue;}if (joArr.get(i) instanceof JSONArray) {JsonArray2HashMap((JSONArray) joArr.get(i), rstList);continue;}System.out.println("Excepton~~~~~");} catch (JSONException e) {e.printStackTrace();}}}public static void json2HashMap(String key, Object value,List<Map<?, ?>> rstList) {HashMap<String, Object> map = new HashMap<String, Object>();map.put(key, value);rstList.add(map);}}

(2)完全Map深层嵌套模式形式：

/** * @param jsonData * @param rstList * @param params * @func hashmap追加字段 */public static void JsonToHashMap(JSONObject jsonData, Map<String, Object> rstList,String... params) {try {for (Iterator<String> keyStr = jsonData.keys(); keyStr.hasNext();) {String key1 = keyStr.next().trim();if (jsonData.get(key1) instanceof JSONObject) {HashMap<String, Object> mapObj = new HashMap<String, Object>();JsonToHashMap((JSONObject) jsonData.get(key1), mapObj, params);rstList.put(key1, mapObj);continue;}if (jsonData.get(key1) instanceof JSONArray) {ArrayList<Map<String, Object>> arrayList = new ArrayList<Map<String, Object>>();JsonToHashMap((JSONArray) jsonData.get(key1), arrayList, params);rstList.put(key1, arrayList);continue;}JsonToHashMap(key1, jsonData.get(key1), rstList);}// 追加字段if (params != null && params.length == 2) {rstList.put(params[0], params[1]);}if (params != null && params.length == 4) {rstList.put(params[0], params[1]);rstList.put(params[2], params[3]);}} catch (JSONException e) {e.printStackTrace();}}public static void JsonToHashMap(JSONArray jsonarray, List<Map<String, Object>> rstList,String... params) {try {for (int i = 0; i < jsonarray.length(); i++) {if (jsonarray.get(i) instanceof JSONObject) {HashMap<String, Object> mapObj = new HashMap<String, Object>();JsonToHashMap((JSONObject) jsonarray.get(i), mapObj, params);rstList.add(mapObj);continue;}}} catch (JSONException e) {e.printStackTrace();}}public static void JsonToHashMap(String key, Object value, Map<String, Object> rstList) {key = BBSUtils.replaceBlank(key);if (value instanceof String) {rstList.put(key, BBSUtils.replaceBlank((String) value));return;}rstList.put(key, value);}public static String getRaw(Context context, int RawId) {try {InputStream is = context.getResources().openRawResource(RawId);BufferedReader reader = new BufferedReader(new InputStreamReader(is));// StringBuffer线程安全；StringBuilder线程不安全StringBuffer sb = new StringBuffer();for (String str = null; (str = reader.readLine()) != null;) {sb.append(str);}return sb.toString();} catch (IOException e) {e.printStackTrace();}return null;}public static String getAsset(Context context, String fileName) {try {InputStream is = context.getResources().getAssets().open(fileName);// StringBuffer线程安全；StringBuilder线程不安全BufferedReader reader = new BufferedReader(new InputStreamReader(is));StringBuffer sb = new StringBuffer();for (String str = reader.readLine(); str != null;) {sb.append(str);}return sb.toString();} catch (IOException e) {e.printStackTrace();}return null;}

备注：

JsonObject里面有两种情况：（1）JsonObject (2)JsonArray 

JsonArray  后面有三种情况：（1）JsonObject (2)JsonArray (3)Object

====================================================

2.调用类：

String jsonStr = Utils.getRaw(mContext, R.raw.file1);String temp = "{\"\":[{\"aa\":\"1\",\"bb\":\"2\"},{\"aa\":\"3\",\"bb\":\"4\"},{\"aa\":\"5\",\"bb\":\"6\"}]}";System.out.println("---------jsonStr" + jsonStr);ArrayList<Map<?, ?>> rstList = new ArrayList<Map<?, ?>>();try {Utils.JsonObject2HashMap(new JSONObject(jsonStr), rstList);Utils.JsonObject2HashMap(new JSONObject(temp), rstList);System.out.println("---------rstList" + rstList);} catch (JSONException e) {e.printStackTrace();}

3.Raw文件夹下文本文件file1：

{
  "programmers": [
    {
      "firstName": "Brett", 
      "lastName": "McLaughlin"
    }, 
    {
      "firstName": "Jason", 
      "lastName": "Hunter"
    }
  ], 
  "authors": [
    {
      "firstName": "Isaac", 
      "lastName": "Asimov"
    }, 
    {
      "firstName": "Tad", 
      "lastName": "Williams"
    }
  ]
}
