my customadapter myadapter.java

public class myadapter extends arrayadapter<string> { context context; int[] images; string[] namearray; string[] mobilearray; string[] genderarray; string[] agearray; string[] diseasearray; string[] dayarray; string[] montharray; string[] yeararray; public myadapter(context c, string[] name, string[] mobile, string[] gender, string[] age, int[] img, string[] disease, string[] day, string[] month, string[] year) { super(c, r.layout.row_layout, r.id.textview1, name); // todo auto-generated constructor stub this.context = c; this.namearray = name; this.mobilearray = mobile; this.genderarray = gender; this.agearray = age; this.diseasearray = disease; this.dayarray = day; this.montharray = month; this.yeararray = year; } @override public view getview(int position, view convertview, viewgroup parent) { // todo auto-generated method stub listview lv; layoutinflater inflater = (layoutinflater) context .getsystemservice(context.layout_inflater_service); view row = inflater.inflate(r.layout.row_layout, parent, false); imageview image = (imageview) row.findviewbyid(r.id.imgview); textview text1 = (textview) row.findviewbyid(r.id.txtname); textview text2 = (textview) row.findviewbyid(r.id.txtmobile); textview text3 = (textview) row.findviewbyid(r.id.txtgender); textview text4 = (textview) row.findviewbyid(r.id.txtage); textview text5 = (textview) row.findviewbyid(r.id.txtdesease); textview text6 = (textview) row.findviewbyid(r.id.txtdate); lv = (listview) row.findviewbyid(r.id.listview1); image.setimageresource(images[position]); text1.settext(namearray[position]); text2.settext(mobilearray[position]); text3.settext(genderarray[position]); text4.settext(agearray[position]); text5.settext(diseasearray[position]); text6.settext(dayarray[position]); text6.settext(montharray[position]); text6.settext(yeararray[position]); homecoming row; }

}

do need write code defining resources obj till setting adapter within onitemselected method ?? suggestions welcomed

i'll next thing:

create method within listadapter named illustration "refreshlist" take parameter info selected spinner item need "get" info need fill list spinner's value selected. illustration if info alter list year function this:

public void refreshlist(string year) { //fill arrays info according year namearray = getresources().getstringarray(r.array.name); //do loas info need according year here //and refresh adapter this.notifydatasetchanged(); }

then in onitemselected phone call of spinner phone call function of listadapter adapter.refreshlist(years[position]) or that. it's thought there many ways this, point have function in adapters called notifydatasetchanged() load 1 time again list info in list/array of info handle within adapter. if spinner selected value alter list info should utilize refresh list when spinner value selected. hope helps
