have an alertDialog with a few items. When an Item is selected, there are some Web services calls and only when they are done the dialog closes. I would like to let the user know he/she shold wait.

I've tried using progress bar and Toast. In the Toast version, if I just show the Toast, it does show - but only after the dialog was closed.

I also tried running the Toast on another thread, which caused the application to crash.

Here is some example of the code:

private void chooseFromClosestSamplePoints(final ArrayList places) {
if (null != places) {
final String[] items = new String[places.size()];
for (int i = 0; i < places.size(); i++) {
Place place = places.get(i);
String displayText = place.mfactoryName + "," + place.msamplePointName;
items[i] = displayText;
}

AlertDialog.Builder builder = new AlertDialog.Builder(
Main.this);
builder.setTitle(R.string.select_sample_point);
builder.setItems(items,
new DialogInterface.OnClickListener() {


public void onClick(DialogInterface dialog,
int which) {
Place place = places.get(which);
Toast toast = Toast.makeText(getApplicationContext(), "אנא המתן", Toast.LENGTH_LONG);
toast.show();
boolean res = selectPlace(place); //this is the long running WS call
if(!res)
{
mStartButton.setEnabled(false);
showAlert("שגיאה","אנא הגדר מחדש עיר מפעל ונקודת דיגום", false);
}
}
});
builder.show();
}
}

Edit: Inside the SelectPlace method , there is some code run on the UI thread itself like so:

private boolean selectPlace(Place place){
GetFactories factoryMethod = new GetFactories(mApp, selectedCity);
factoryMethod.call(); //This calls the WS and awaits results

final ArrayList factories =factoryMethod.getFactories();
Factory selectedFactory = null;
for(int i = 0; i < factories.size(); i++)
{
///Some logic
}

//Some more logic...
}
