oid.settext(sdata.getoid()); giving me values , not exception. 

but when want display data in textview. giving me nullpointer exception.

this code:-

griddata gdata = new griddata(search.this,r.layout.griditem,r); gridview.setadapter(gdata);  public class griddata extends arrayadapter<searchdata> { context context; private arraylist<searchdata> items;  public griddata(context context, int textviewresourceid, arraylist<searchdata> items) {     super(context, textviewresourceid, items);     this.items = items; }   @override  public int getcount()    {  //return numbers of element u want on grid   return items.size();  }   @override  public view getview(int position, view convertview, viewgroup parent)    {    view v;    if (convertview == null) {        layoutinflater vi = (layoutinflater)getsystemservice(context.layout_inflater_service);        v = new view(context);        v = vi.inflate(r.layout.griditem, null);    } else    {        v = convertview;    }     searchdata sdata = items.get(position);    system.out.println("the data "+sdata.getoid());    if(sdata != null)    {      textview oid = (textview) findviewbyid(r.id.oid);     oid.settext(sdata.getoid());  /*    textview odate = (textview) findviewbyid(r.id.odate);      textview osdate = (textview) findviewbyid(r.id.osdate);      textview semail = (textview) findviewbyid(r.id.semail);      textview ssaddress = (textview) findviewbyid(r.id.ssaddress);      textview shipzip = (textview) findviewbyid(r.id.shipzip);      textview scost = (textview) findviewbyid(r.id.scost);      textview noofi = (textview) findviewbyid(r.id.noofi);      textview noofc = (textview) findviewbyid(r.id.noofc);      textview handfee = (textview) findviewbyid(r.id.handfee);       oid.settext(sdata.getoid());      /*odate.settext(sdata.getodate());     osdate.settext(sdata.getosdate());     semail.settext(sdata.getsemail());     ssaddress.settext(sdata.getssaddress());     shipzip.settext(sdata.getszip());     scost.settext(sdata.getscost());     noofi.settext(sdata.getnoofi());     noofc.settext(sdata.getnoofc());     handfee.settext(sdata.gethannlgfee());*/     }     return v;}  @override  public searchdata getitem(int arg0) {    return items.get(arg0);  }  @override public long getitemid(int arg0) {  // todo auto-generated method stub  return arg0;} }

i think problem may in getitem.xml. please except me. thank timing.

change this

textview oid = (textview) findviewbyid(r.id.oid); oid.settext(sdata.getoid());  

to this

textview oid = (textview) v.findviewbyid(r.id.oid); oid.settext(sdata.getoid());
