Как применить данные из файла CSV, которые я могу получить в виде списка, к автозаполнению Edittext?

Question

Я пишу код ниже, так что кто-нибудь может мне помочь, как разместить этот список данных массива в Autocomplete Textview?Я могу извлечь данные из файла CSV в список массивов, но я хочу только имя станции в автозаполнении Textview.

public class SecondActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);

    readstationdata();
}

private List<Stationname> Stationname= new ArrayList<>();
private void readstationdata() {
    InputStream is = getResources().openRawResource(R.raw.train_details_22122017);
    BufferedReader reader = new BufferedReader(
            new InputStreamReader(is, Charset.forName("UTF-8"))
    );

    String line = "";
    try {
        while ((line = reader.readLine()) != null) {
            String[] tokens = line.split(",");

            Stationname name = new Stationname();
            name.setTrain_No(Integer.parseInt(tokens[0]));
            name.getTrain_Name(tokens[1]);
            name.getSeq(Integer.parseInt(tokens[2]));
            name.getStation_Code(tokens[3]);
            name.getStation_Name(tokens[4]);
            name.getArrival_Time(Time.valueOf(tokens[5]));
            name.getDeparture_Time(Time.valueOf(tokens[6]));
            name.getDistance(Integer.parseInt(tokens[7]));
            name.getSource_Station(tokens[8]);
            name.getSource_Station_Name(tokens[9]);
            name.getDestination_Station(tokens[10]);
            name.getDestination_Station_Name(tokens[11]);

            Stationname.add(name);
            Log.d("Myactivity","Just created: " + name);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

}
}

Этот код был написан в SecondActivity.java

И ниже код дляStationname.java

}

public void setDestination_Station_Name(String destination_Station_Name) {
    Destination_Station_Name = destination_Station_Name;
}

@Override
public String toString() {
    return "Stationname{" +
            "Train_No=" + Train_No +
            ", Train_Name='" + Train_Name + '\'' +
            ", Seq=" + Seq +

            ", Destination_Station_Name='" + Destination_Station_Name + '\'' 
+
            '}';
}

}

А что писать в файле activity_second.xml?
Заранее спасибо.
