Have you tried using android:completionThreshold="1" inside AutoCompleteTextView?

or called mAutoCompleteTextView.setThreshold(1) to AutoCompleteTextView reference?

mAutoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView);

Set your AutoCompleteTextView with Custom Adapter

mAutoCompleteTextView.setSelection(0);
mCustomAutoFilterAdapter = new CustomAutoFilterAdapter(this,R.layout.spinner_row, yourList);
mAutoCompleteTextView.setThreshold(1);
mAutoCompleteTextView.setAdapter(mCustomAutoFilterAdapter);

In your Custom Adapter Class include

public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;
    if (v == null) {
        LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(viewResourceId, null);
    }     
    return v;
}

@Override
public Filter getFilter() {
    return nameFilter;
}

Filter nameFilter = new Filter() {
    @Override
    public String convertResultToString(Object resultValue) {
        String str = "get your values from resultValue";
        return str;
    }
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        if(constraint != null) {
            suggestions.clear();
              "DO your Activities"
            }
            FilterResults filterResults = new FilterResults();
            filterResults.values = suggestions;
            filterResults.count = suggestions.size();
            return filterResults;
        } else {
            return new FilterResults();
        }
    }
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
       "Do your Activities here"
    }
};

hi, i still dont get it, what should i do in perform filtering and publish result. — gilllsss, Mar 13 '17 at 08:06
