inside listview inflating layout have checkbox.now btnclear want uncheck checkboxes .how can please me in this

create loop going through child items of listview , check if view of type checkbox , perform setchecked(false) on same.

for (int = 0; < mlistview.getcount(); i++) {         view mchild = mlistview.getchildat(i);         //replace r.id.checkbox id of checkbox in layout        checkbox mcheckbox = (checkbox) mchild.findviewbyid(r.id.checkbox);        mcheckbox.setchecked(false); }
