android - View show's error in List View -

-

i have prolblem list view.i have placed edittext in listview entering data list of items in list view.i have took data edittext row row listview.\

i can see 5 row in listview , next reows need scroll list view.

the problem arise here can took data listview upto 5 rows view means of took valuse form edittext in list.

but when comes 6th row shows null pointer exception plced identify edittext.(textview decatered_load = (textview) vlvtopup.findviewbyid(r.id.etconfirmdecaterednumber);) point of error arise @ here.

        (int = 0; < lvconfirmdecater.getadapter().getcount(); i++) {                  hashmap result = (hashmap) lvconfirmdecater.getitematposition(i);                 view vlvtopup;                 vlvtopup = lvconfirmdecater.getchildat(i);                  textview decatered_load = (textview) vlvtopup                         .findviewbyid(r.id.etconfirmdecaterednumber);                  textview decatered_reason = (textview) vlvtopup                         .findviewbyid(r.id.etconfirmdecateredreason);                  textview nondecatered_load = (textview) vlvtopup                         .findviewbyid(r.id.etconfirmnondecaterednumber);

so note error increased number of rows in list can view upto 10 can took data edit text upto 10.after shows error.

did have idea .why didnt identfy view
