[HashMap: key -> value ] to ListView

` /**
* Will get the data from the map data structure, not the best solution, but it will work

public void fetchNotes() {

        adapter = new ArrayAdapter<>(getApplicationContext(), R.layout.support_simple_spinner_dropdown_item, getArrayList());
        listview.setAdapter(adapter);

        Map<String, Object> map = getMap("map", ShowNotes.this);

        if(map != null) {
            Iterator myVeryOwnIterator = map.keySet().iterator();
            while (myVeryOwnIterator.hasNext()) {
                String key = (String) myVeryOwnIterator.next();
                String value = (String) map.get(key);
                push(value + "\n" + key);
            }
            adapter.notifyDataSetChanged();
        } else {
            Toast.makeText(getApplicationContext(), "There is no notes to print, maybe you should make some notes first!", Toast.LENGTH_LONG).show();
        }
    }`

There must be a more nice way to add data from a hashmap to a listview without having to use an ArrayList, how to do this properly?
