android.R.layout.simple_spinner_item, businessType);
spBusinessType.setAdapter(adapterBusinessType);

// create Item Selected Listener
spBusinessType.setOnItemSelectedListener(new OnItemSelectedListener() {

@Override
public void onItemSelected(AdapterView<?> adapter, View v,
int position, long id) {
