在网上查了一些资料后，精简改写后得出自己想用的形式，记录一下

public static void putHashMapData(Context context, String key, Map datas) {

JSONArray mJsonArray = new JSONArray();

Iterator> iterator = datas.entrySet().iterator();

JSONObject object = new JSONObject();

while (iterator.hasNext()) {

Map.Entry entry = iterator.next();

try {

object.put(entry.getKey(), entry.getValue());

} catch (JSONException e) {

}

}

mJsonArray.put(object);

SharedPreferences sp = context.getSharedPreferences("config",

Context.MODE_PRIVATE);

SharedPreferences.Editor editor = sp.edit();

editor.putString(key, mJsonArray.toString());

editor.commit();

}

public static Map getHashMapData(Context context, String key) {

Map datas = new HashMap<>();

SharedPreferences sp = context.getSharedPreferences("config",

Context.MODE_PRIVATE);

String result = sp.getString(key, "");

try {

JSONArray array = new JSONArray(result);

for (int i = 0; i < array.length(); i++) {

JSONObject itemObject = array.getJSONObject(i);

JSONArray names = itemObject.names();

if (names != null) {

for (int j = 0; j < names.length(); j++) {

String name = names.getString(j);

String value = itemObject.getString(name);

datas.put(name, value);

}

}

}

} catch (JSONException e) {

}

return datas;

}
