AutoCompleteTextView not completing words inside parentheses

Question

I have implemented AutoCompleteTextView as follows:

MainActivity.java

...
    public static String[] myData=new String[]{"Africa (AF)","America (AFM)","Apple (AMP)"};
    text=(AutoCompleteTextView)v.findViewById(R.id.first_state);
    ArrayAdapter adapter = new ArrayAdapter(getActivity(),R.layout.autocompletetextview_row,R.id.textViewItem,myData);

    text.setAdapter(adapter);
    text.setThreshold(1);
    text.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) {

            selected_station = (String)parent.getItemAtPosition(position);
            //TODO Do something with the selected text
        }
    });

In layout of AutoCompleteTextView:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFFFFF"
    android:padding="10dp" >
    <TextView
        android:id="@+id/textViewItem"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="Item name here..."
        android:textColor="#000000"
        android:textSize="20sp" />
 </RelativeLayout>

When I type like "af..", it shows me Africa (AF) to select but not America (AFM).

The data is just an example data. it's not that I am using AutoCompleteTextView for just 3 items.

EDIT: when I remove the parentheses, it works properly. But I need to keep the parentheses for further use.

An answer, provided by @BNK, is correct. However, I would like to give a similar solution, which doesn't require the whole ArrayAdapter class file. Instead, we will just extend that class and override its only 2 methods: getView() and getFilter(). So, define your AutoSuggestAdapter class:

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Filter;
import android.widget.TextView;

import java.util.ArrayList;
import java.util.List;

public class AutoSuggestAdapter extends ArrayAdapter
{
    private Context      context;
    private int          resource;
    private List<String> items;
    private List<String> tempItems;
    private List<String> suggestions;

    public AutoSuggestAdapter(Context context, int resource, List<String> items)
    {
        super(context, resource, 0, items);

        this.context = context;
        this.resource = resource;
        this.items = items;
        tempItems = new ArrayList<String>(items);
        suggestions = new ArrayList<String>();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        View view = convertView;
        if (convertView == null)
        {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(resource, parent, false);
        }

        String item = items.get(position);

        if (item != null && view instanceof TextView)
        {
            ((TextView) view).setText(item);
        }

        return view;
    }

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

    Filter nameFilter = new Filter()
    {
        @Override
        public CharSequence convertResultToString(Object resultValue)
        {
            String str = (String) resultValue;
            return str;
        }

        @Override
        protected FilterResults performFiltering(CharSequence constraint)
        {
            if (constraint != null)
            {
                suggestions.clear();
                for (String names : tempItems)
                {
                    if (names.toLowerCase().contains(constraint.toString().toLowerCase()))
                    {
                        suggestions.add(names);
                    }
                }
                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)
        {
            List<String> filterList = (ArrayList<String>) results.values;
            if (results != null && results.count > 0)
            {
                clear();
                for (String item : filterList)
                {
                    add(item);
                    notifyDataSetChanged();
                }
            }
        }
    };
}

Define auto complete view in XML for example:

       <AutoCompleteTextView
        android:id="@+id/autoComplete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="Enter some text ..."/>

And use it:

    AutoCompleteTextView autoComplete = (AutoCompleteTextView) findViewById(R.id.autoComplete);

    List <String> stringList = new ArrayList<String>();
    stringList.add("Black");
    stringList.add("White");
    stringList.add("Yellow");
    stringList.add("Green");
    stringList.add("Blue");
    stringList.add("Brown");
    stringList.add("Orange");
    stringList.add("Pink");
    stringList.add("Violet");
    stringList.add("Cyan");
    stringList.add("LightBlue");

    AutoSuggestAdapter adapter = new AutoSuggestAdapter(this, android.R.layout.simple_list_item_1, stringList);

    autoComplete.setAdapter(adapter);

    // specify the minimum type of characters before drop-down list is shown
    autoComplete.setThreshold(1);
