Setting up Spinner filled with data without any reference to Android resources

Question

Busy creating an interface with spinner (dropdown) programmatically. To populate with data you need an (Array)Adapter. What I don't understand is why you need a reference to an Android resource at all, like "android.R.layout.simple_spinner_dropdown_item". Is it possible to populate the Spinner with webservice data, without any reference to such an Android resource? If not, why not and how should this resource look like, in an environment without layout's. If it is possible, please show me how, since google is no help here (to me).

Thanks in advance!

Update:

Spinner spinner = new Spinner(this.getActivity());
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this.getActivity(), whatComesHere, list);
spinner.setAdapter(dataAdapter);
tableRow.addView(spinner);

The questions is: what to substitute for 'whatComesHere'?

thanks in advance.

Update-2

<Spinner
    android:id="@+id/spinner_admin_platform"
android:layout_width="wrap_content"
android:layout_height="wrap_content" 
android:layout_marginLeft="5dip"
android:layout_marginRight="5dip"
android:layout_marginTop="5dip"
android:layout_marginBottom="5dip"
android:entries="@array/my_spinner" />

Answer 1

Here is an example:

 private void FillCitySnipper() {
ArrayList<MyCity> ListOfCity=db.LoadMyCity();
            // TODO Auto-generated method stub
            if (ListOfCity.size() > 0) {
                Spinner spinner = (Spinner) this
                        .findViewById(R.id.spnr_Cityname);
                ArrayAdapter<MyCity> spinnerArrayAdapter = new ArrayAdapter<MyCity>(
                        this,
                        android.R.layout.simple_spinner_dropdown_item,
                        ListOfCity);
                spinner.setAdapter(spinnerArrayAdapter);
            }
    }
