HashMap<String,String> my_groud_id = new HashMap<String,String>();

my_group_id.put("ko","한국어");

my_group_id.put("en","영어");

Iterator<Entry<String, String>> iter = my_group_id.entrySet().iterator();    

while (iter.hasNext()) {

Entry<String, String> mEntry = iter.next();

Log.i("my_group_id",mEntry.getKey() + " : " + mEntry.getValue());

}
