inside oncreate:

this.getlistview().setonitemclicklistener(listener); 

arg0.getadapter().getitemid(arg2) should replaced arg2, because arg2 position of clicked list's element. think getting arrayindexoutofboundsexception because trying element of array not element's position, element's id! element's id example 100203102031230.
