Well, i wrote simple it will help you

Override onContentChanged() method

Like below:

@Override
    public void onContentChanged() {
        super.onContentChanged();
        // write you code here, when list view empty.
    }

Change the following:

 mListview.setEmptyView(getActivity().
 findViewById(R.id.emptyElement));
 mListview.setAdapter(mAdapter);

to

mListview.setAdapter(mAdapter); 
mListview.setEmptyView(getActivity(). findViewById(R.id.emptyElement));

Bind the listview first and then set the empty view.
