If you parse set of data from xml, json, database, etc it's better to create custom model i.e. your model:

public class YourModel
{
    private int id = -1;
    private String title = "";

    public int getId()
    {
        return id;
    }

    public void setId(int id)
    {
        this.id = id;
    }

    public String getTitle()
    {
        return title;
    }

    public void setTitle(String title)
    {
        this.title = title;
    }
}

In activity:

private YourModel yourModel;

@Override
public void onCreate(Bundle savedInstanceState)
{
    lstView.setOnItemClickListener(new OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> parent, View v, int position,
                    long id)
        {
            detailsModel = ((YourAdapter) lstView.getAdapter()).getItem(position);
            Toast.makeText(getApplicationContext, yourModel.getTitle(),
                Toast.LENGTH_LONG).show();
        }
    }
}
