setEmptyView when edittext is empty using textwatcher

Question

I'm using a custom calendar from this link. Its working but the dates of all the months except current month has been grayed out. I want to display all months when viewed like the 2nd screenshot. But it grays out all months except the current month (i.e. April). Can anyone help me in displaying each month like the 2nd screenshot and not like 1st screenshot?

Calendar View:

public class CalendarView extends LinearLayout
{
 // for logging
 private static final String LOGTAG = "Calendar View";

 // how many days to show, defaults to six weeks, 42 days
 private static final int DAYS_COUNT = 42;

 // default date format
 private static final String DATE_FORMAT = "MMM yyyy";

 // date format
 private String dateFormat;

 // current displayed month
 private Calendar currentDate = Calendar.getInstance();

 //event handling
 private EventHandler eventHandler = null;

 // internal components
 private LinearLayout header;
 private ImageView btnPrev;
 private ImageView btnNext;
 private TextView txtDate;
 private GridView grid;

 // seasons' rainbow
 int[] rainbow = new int[] {
   R.color.summer,
   R.color.fall,
   R.color.winter,
   R.color.spring
 };

 // month-season association (northern hemisphere, sorry australia :)
 int[] monthSeason = new int[] {2, 2, 3, 3, 3, 0, 0, 0, 1, 1, 1, 2};

Get the date that is set in the heade, using txtDate.getText();

 SimpleDateFormat sdf = new SimpleDateFormat(dateFormat);
    Date currentSelectedDate = sdf.parse(using txtDate.getText());


if (month != currentSelectedDate.getMonth() || year != currentSelectedDate.getYear())
