Question

Here is the layout I am trying to get. As long as I don’t actually try to populate my spinners, everything loads just fine. Based on what I have found in my searches and the log is that I need to use a TextView with the ArrayAdapter. Exactly how I do that while preserving the current layout – Spinners and a submit button at the top with a ListView for the returned results below the spinners is what I am having trouble achieving.

Here is my onCreate method.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.master);
        DBHelper db = new DBHelper(this);
        List<Stations> st = db.getAllStations();
        List<CharSequence> stations = new ArrayList<CharSequence>();
        setList(4, 9);
        for (int i = 0; i < st.size(); i++)
        {
            stations.add(st.get(i).getStation());
        }
        ListView list = (ListView) findViewById(R.id.list);
        Spinner s1 = (Spinner) findViewById(R.id.spinnerStart);
        Spinner s2 = (Spinner) findViewById(R.id.spinnerEnd);

        ArrayAdapter<CharSequence> SimpleSpinner1 = new ArrayAdapter<CharSequence>(this, R.layout.spinner, R.id.textView1);
        ArrayAdapter<CharSequence> SimpleSpinner2 = new ArrayAdapter<CharSequence>(this, R.layout.spinner, R.id.textView1);
        SimpleAdapter nSchedule = new SimpleAdapter(this, departures, R.layout.row,
            new String[] {"train", "from", "to"}, new int[] {R.id.TRAIN_CELL, R.id.FROM_CELL, R.id.TO_CELL});
        for (CharSequence c : stations)
        {
            SimpleSpinner1.add(c);
            SimpleSpinner2.add(c);
        }
    list.setAdapter(nSchedule);
    s2.setAdapter(SimpleSpinner2);
    s1.setAdapter(SimpleSpinner1);

    }

Answer 1

Instead of R.id.spinnerStart / R.id.spinnerEnd you need to pass a textView

EDIT:

Spinner spinner1 = (Spinner)findViewById(R.id.spinner1);
ArrayAdapter adapter = new ArrayAdapter(this, R.layout.spinner_item, R.id.textView1);
spinner1.setAdapter(adapter);

textView1 is present in spinner_item layout. Hope this is clear
