android - custom adapter with ArrayList<HashMap<String, List<String>>> -

its complicated question, hope can me.

i want make custom adapter can handle

array list mentioned in title

currently doing this, not going getview(...) method.

public class eventsadapter extends baseadapter{  arraylist<hashmap<string, list<string>>> eventlist;  private context context; private int resource;     private static final string tag_title = "e_title";   public eventsadapter(context context, int resid,arraylist<hashmap<string, list<string>>> eventlist) {      this.context = context;     this.resource = resid;     this.eventlist = eventlist;     log.v("chk", "1");  }  @override public view getview(int position, view convertview, viewgroup parent) {       view event = convertview;      textview title, desc, date, time, venue;      hashmap<string, list<string>> hm = eventlist.get(position);        list<string> items = hm.get(tag_title);      typeface font = typeface.createfromasset(context.getassets(), "ubahn.ttf");       if( event == null )     {         layoutinflater inflater = ((activity) context).getlayoutinflater();         event = inflater.inflate( resource , parent, true  );         event.settag(items.get(position));     }      title = (textview) event.findviewbyid( r.id.etitle);     desc = (textview) event.findviewbyid( r.id.edesc );     date = (textview)event.findviewbyid(r.id.edate);     time = (textview)event.findviewbyid(r.id.etiming);     venue = (textview)event.findviewbyid(r.id.elocation);      title.settypeface(font);        system.out.print(items.get(0).tostring());      title.settext(items.get(0).tostring());     desc.settext(items.get(1).tostring());     date.settext(items.get(2).tostring());     time.settext(items.get(3).tostring());     venue.settext(items.get(4).tostring());      return event; }  @override public int getcount() {     // todo auto-generated method stub     return 5; }  @override public object getitem(int position) {     // todo auto-generated method stub     return eventlist.get(position).get(position).get(position); }  @override public long getitemid(int position) {     // todo auto-generated method stub     return position; } 

}

any appreciated.

here how filling data in array list

    (int = 0; < products.length(); i++) {                     jsonobject c = products.getjsonobject(i);                      // storing each json item in variable                     string title = c.getstring(tag_title);                     string description = c.getstring(tag_desc);                     string date = c.getstring(tag_date);                     string time = c.getstring(tag_time);                     string venue = c.getstring(tag_venue);                      // creating new hashmap                      hashmap<string, list<string>> map = new hashmap<string, list<string>>();                      list<string> el = new arraylist<string>();                     el.add(title);                     el.add(description);                     el.add(date);                     el.add(time);                     el.add(venue);                      // adding each child node hashmap key => value                     map.put(tag_title, el);                    // map.put(tag_desc, description);                     //muap.put(tag_date, date);                      // adding hashlist arraylist                     eventlist.add(map);                 } 

and here setting adapter

eventsadapter adapter = new eventsadapter(getactivity(), r.layout.events_list_item, eventlist);                    lv.setadapter( adapter); 

i think useful consider when filling list.

a design pattern create data empty hashmap, establish adapter map, declare listview( or whatever ) , assign adapter empty data set. later, fill hashmap, , adapter.notifydatasetchanged

i declare these feilds:

    //array of places filtered keyword list<place> places = new arraylist<place>( );     //spinner of places filtered keyword spinner placesspinner; //adapter spinner private placesspinneradapter placesspinneradapter; 

in oncreate:

//this spinner, same difference placesspinner = (spinner)findviewbyid( r.id.placesspinner ); placesspinneradapter = new placesspinneradapter( this,                             android.r.layout.simple_spinner_dropdown_item, places ); placesspinner.setadapter( placesspinneradapter ); 

and somewhere in onpostexecute method of asynctask have no interest in

places.clear( ); places.addall( result.results ); placesspinneradapter.notifydatasetchanged( ); placesspinner.performclick( ); 

and lastly, here's difference see: adapters lists, i've never had time passing them hashmaps... map.keyset() or map.values(); hand data on adapter; know standard pattern described not work if data set hashmaps
