Forcing AutoCompleteTextView dropdown List

Question

I am making an Async request to download some data once the data is downloaded i clear the old list and add the new items in the onPostExecute() of the Async to the adapter of AutoCompleteTextView and I call

adapter.setNotifyOnChange(true);
adapter.notifyDataSetChanged();

But i am not able to show the dropdown again ?? Any suggestion would be most appreciated

please post the entire onPostExecute() code – Maggie Nov 20 '13 at 22:07 — Maggie, Nov 20 '13 at 22:07

I solved it here is the solution

All I needed was to reinitialze the variable and call the notify the dataset has changed

arrayAdapter =  new ArrayAdapter<String> (this,android.R.layout.select_dialog_item,newDownloadedList);
AutoCompleteTextView.setAdapter(arrayAdapter);
arrayAdapter.notifyDataSetChanged();

you can use this

   arrayAdapter =  new ArrayAdapter<String> 
   (this,android.R.layout.select_dialog_item,newList);
   AutoCompleteTextView.setAdapter(arrayAdapter);
   arrayAdapter.notifyDataSetChanged();

then call AutoCompleteTextView.showDropDown();
