Question

How can I change the text color in dropdown menu of an AutoCompleteTextView? Or how can I change the background color of a dropdown, by default dropdown\'s back

Answer 1

It is actually not possible to direct change the color of the auto-complete textView by default. Instead you have to implement the custom adapter for such and inflating the view from adapter usually textView. See this question which will help u to solve your problem. So you can set the properties to the textview as you want.. e.g You must have the custom adapter like below

public class MyCustomBrandAdapter extends ArrayAdapter{


List Brandlist;
Context context;
private ArrayList itemsAll;
private ArrayList suggestions;
public MyCustomBrandAdapter(Context context, int textViewResourceId, List Brandlist) 
{
    
    super(context,  textViewResourceId, Brandlist);
    this.Brandlist =  Brandlist;
    this.itemsAll = (ArrayList) ((ArrayList) Brandlist).clone();
    this.suggestions = new ArrayList();
    this.context = context;
}


public View getView(int position, View convertView, ViewGroup parent) 
{
    View v = convertView;
    if (v == null) {
        LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.listview, null);

    }
    Brand Brand = Brandlist.get(position);
    if (Brand != null) {
        TextView tt = (TextView) v.findViewById(R.id.txtName);
        
        if (tt != null) {
            tt.setText(Brandlist.get(position).toString());
        } else {
            System.out.println("Not getting textview..");
        }
    
    }
    return v;
}
 @Override
    public Filter getFilter() {
        return nameFilter;
    }

    Filter nameFilter = new Filter() {
        public String convertResultToString(Object resultValue) {
            String str = ((Brand)(resultValue)).getBrandDescription1(); 
            return str;
        }
        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            if(constraint != null) {
                suggestions.clear();
                for (Brand brand : itemsAll) {
                    if(brand.getBrandDescription1().toLowerCase().startsWith(constraint.toString().toLowerCase())){
                        suggestions.add(brand);
                    }
                }
                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) {
            ArrayList filteredList = (ArrayList) results.values;
            List getResult=new ArrayList();
            if(results != null && results.count > 0) {
                clear();
                for (Brand c : filteredList) {
                    getResult.add(c);
                }
                Iterator brandIterator=getResult.iterator();
                while(brandIterator.hasNext()){
                    Brand party=brandIterator.next();
                    add(party);
                }
                notifyDataSetChanged();
            }
        }
    };
    
}

and in this the layout R.layout.listview xml is as follows

Here in this xml. I have set background as white (android:background="#ffffff") and I want text as black (android:textColor="#000000") and size as (android:textSize="12dp") as I want it modified.. I think now it will get u clearly.
