@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
  super.onCreateContextMenu(menu, v, menuInfo);

  // Get the info on which item was selected
  AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;

  // Get the Adapter behind your ListView (this assumes you're using
  // a ListActivity; if you're not, you'll have to store the Adapter yourself
  // in some way that can be accessed here.)
  Adapter adapter = getListAdapter();

  // Retrieve the item that was clicked on
  Object item = adapter.getItem(info.position);
}

@Override
public boolean onContextItemSelected(MenuItem item) {
  // Here's how you can get the correct item in onContextItemSelected()
  AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
  Object item = getListAdapter().getItem(info.position);
}
