android - passing a List of string by putExtra method using intent -

i have class named register_information looks

// getting name public string get_name() {     return this.name; } // setting name public void set_name(string name) {     this.name=name; } 

i used code of name , password registered mainactivity this.

list<register_information> all_reg_info_lists = db.get_all_info();               list<hashmap<string, string>> list_of_reg_info = new arraylist<hashmap<string, string>>();                (register_information reg_info : all_reg_info_lists)               {                                    hashmap<string, string> hm = new hashmap<string, string>();                    string name = reg_info.get_name();                     string password=reg_info.get_password() ;                        hm.put("key_name",name);                       hm.put("key_password",password);                        list_of_reg_info.add(hm);                    } 

now want pass these name , password window showing them list-view intent. used intent

intent intobj = new intent(mainactivity.this,showdata_in_textview_class.class);                      intobj.putextra("data", list_of_reg_info);             startactivity(intobj); 

in showdata_in_textview_class received intent this

public class showdata_in_textview_class extends activity{     arrayadapter adapter;    list<register_information> reg_info_lists;    public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.listview_xml_page);           intent intename = getintent();         reg_info_lists= (list)intename.getserializableextra("data");  }  

}

but didn't work. how can that??

you can pass serializable variable intent. instead of list not serializable, use arraylist is.
