android - Calling A List of a Hashmap of a list. (Java) -
this variable
private arraylist<hashmap<string, string>> usersinfo = new arraylist<hashmap<string, string>>();
i keep adding info usersinfo
hashmap.put(tag_username, data_obj.getstring(tag_username)); usersinfo.add(hashmap);
how can print array or print index info put in it?
you can print values of arraylist follows:
userinfo.stream.foreach((map)-> { for(string key : map.getkeys()){ system.out.println("key: " + key + ", value: " + map.get(key)); } })
or if want specific map @ index, use following:
map map = userinfo.get(0); for(string key : map.getkeys()){ system.out.println("key: " + key + ", value: " + map.get(key)); }
