android - How to get last ListView item position -


i created listview radiobutton. listview image below: enter image description here

and getview is:

public view getview(final int position, view convertview, viewgroup parent) {     viewholder holder = null;     paymentdata rowitem = getitem(position);     layoutinflater minflater = (layoutinflater) context             .getsystemservice(context.layout_inflater_service);     if (convertview == null) {         convertview = minflater.inflate(                 com.android.paypal.homeactivity.r.layout.list_item, null);         holder = new viewholder();         holder.radiobtn = (radiobutton) convertview                 .findviewbyid(com.android.paypal.homeactivity.r.id.rdb_payment_method);         holder.btpaymentmethod = (button) convertview                 .findviewbyid(com.android.paypal.homeactivity.r.id.bt_item_event);         convertview.settag(holder);     } else         holder = (viewholder) convertview.gettag();      holder.radiobtn.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {              if ((position != mselectedposition) && (mselectedrb != null)) {                 mselectedrb.setchecked(false);             }              mselectedposition = position;             mselectedrb = (radiobutton) v;         }     });      if (mselectedposition != position) {         holder.radiobtn.setchecked(false);     } else {         holder.radiobtn.setchecked(true);         if (mselectedrb != null && holder.radiobtn != mselectedrb) {             mselectedrb = holder.radiobtn;         }     }      holder.radiobtn.settext(rowitem.getrdbtext());     holder.btpaymentmethod.settext(rowitem.getbttext());     return convertview;  }

i want auto checked last radiobutton when screen comes first. how can achieve this.

hold boolean whether user has himself selected anything. let boolean userselected = false;

now in getview():

if(position==getcount()-1 && userselected==false)     holder.radiobtn.setchecked(true); else     holder.radiobtn.setchecked(false);

in onitemclick, when user has made selection himself, set userselected=true;
