android autocompletetextview hint results hidden under keyboard

Question

I have 3 autocompletetextview's in which i set its adapter to be an ArrayAdapter with a very simple textview layout.

the autocompletextview hint results are showing, but are under the onscreen keyboard(i can see part of it). how can i make the results show above the autocompletetextview rather than below?

    airline = (AutoCompleteTextView)findViewById(R.id.airline);
    airline.setAdapter(new ArrayAdapter<String>(this, R.layout.autcomplete_dropdown, AIRLINES_AUTOCOMPLETE_ARRAY));

    departLocation = (AutoCompleteTextView)findViewById(R.id.departLocation);
    departLocation.setAdapter(new ArrayAdapter<String>(this, R.layout.autcomplete_dropdown, LOCATIONS_AUTOCOMPLETE_ARRAY));

    arriveLocation = (AutoCompleteTextView)findViewById(R.id.arriveLocation);
    arriveLocation.setAdapter(new ArrayAdapter<String>(this, R.layout.autcomplete_dropdown, LOCATIONS_AUTOCOMPLETE_ARRAY));
