public class favorite { private int favoritethumbnail; private string favoritename; public favorite(int favoritethumbnail, string favoritename){ super(); this.favoritethumbnail = favoritethumbnail; this.favoritename = favoritename; } public int getthumbnail(){ return favoritethumbnail; } public string getname(){ return favoritename; } } favorite_row.xml

add 2 buttons getview method, , include them in handler, on pass through getview method want assign click listener this:
holder.btndelete.setonclicklistener(new onclicklistener() { string btnmsg = "getting delete " + favoriteclicked.getname(); @override public void onclick(view v) { toast.maketext(favoriteactivity.this, btnmsg, toast.length_long).show(); } }); so viewholder class this:
static class viewholder { imagebutton thumbnail; textview name; imagebutton btndelete; imagebutton btndirections; } and set buttons in getview() method per other views
holder.btndirections=(imagebutton)itemview.findviewbyid(r.id.favoritedirections); holder.btndelete=(imagebutton)itemview.findviewbyid(r.id.favoritedelete);
