implementation in listfragment

list <compra> compras = db.getallcompras(id_user); newlistviewadapter adapter = new newlistviewadapter(getactivity(), compras); setlistadapter(adapter); getlistview(); registerforcontextmenu(getlistview());

my plans show listview if user touch 1 element of listview user can take if modify or delete , need "compra" id. thats why im showing info , need take id. modify or delete it.

thanks.

to handle list item click in android can user onlistitemclick method. 1 scenario of handling modify , or delete alternative have alert dialog pop options. can decide take user activity , handle modification , deletion of object there. whatever works best you.
