AutoCompleteTextView not showing any drop down items

Question

My XML:

Answer 1

this is a snippet from my project. I think after you got data from services all you have to do is to:

1. clear your previous data.
2. clear the previous adapter values.
3. then add values to your list of data using add() or addAll() method.

4. notify the data changed by calling notifyDataSetChanged() on adapter.

   @Override
   public void onGetPatient(List patientSearchModelList) {
   
   //here we got the raw data traverse it to get the filtered names data for the suggestions
   
   stringArrayListPatients.clear();
   stringArrayAdapterPatient.clear();
   for (PatientSearchModel patientSearchModel:patientSearchModelList){
   
       if (patientSearchModel.getFullName()!=null){
   
           stringArrayListPatients.add(patientSearchModel.getFullName());
   
       }
   
   }
   
   //update the array adapter for patient search
   stringArrayAdapterPatient.addAll(stringArrayListPatients);
   stringArrayAdapterPatient.notifyDataSetChanged();
   

   }

but before all this make sure you have attached the adapter to the auto complete textview if don't do it as follows:

ArrayAdapter stringArrayAdapterPatient= new ArrayAdapter(getActivity(),android.support.v7.appcompat.R.layout.select_dialog_item_material,stringArrayListPatients);

completeTextViewPatient.setAdapter(stringArrayAdapterPatient);
