I this code I am using web service to load data dynamically to the spinner. And data is properly loaded in it. But when I click on spinner to select an item the selected item does not displayed in spinner.
public class MainActivity extends Activity
{
TextView webserviceResponse;
private Button btnCheck;
public String set;
private ProgressDialog prgDialog;
public static final int progress_bar_type = 0;
List<String> allNames=new ArrayList<String>();
private Spinner spinCityName;
ArrayAdapter<String> dataAdapter;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
spinCityName=(Spinner)findViewById(R.id.spinCity);
dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item,allNames);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
dataAdapter.notifyDataSetChanged();
spinCityName.setAdapter(dataAdapter);
new temp().execute("GetCities");
}
@Override
protected Dialog onCreateDialog(int id)
{
switch (id)
{
case progress_bar_type:
prgDialog = new ProgressDialog(this);
prgDialog.setMessage("Please wait..");
prgDialog.setIndeterminate(false);
prgDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
prgDialog.setCancelable(false);
prgDialog.show();
return prgDialog;
default:
return null;
}
}
