Try to implement with GridView, below code for Gridview Adapter :

public class GridCellAdapter extends BaseAdapter //implements OnClickListener 
 {
  private final Context _context;

  private final List list;
  private static final int DAY_OFFSET = 1;
  private final String[] months = { "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct","Nov", "Dec" };
  private final int[] daysOfMonth = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };
  private int daysInMonth;
  private int currentDayOfMonth;
  private int currentWeekDay;
  Calendar calendar;
  private Button gridcell;

  List objects;

  // Days in Current Month
  public GridCellAdapter(Context context, int textViewResourceId, int month, int year, List objects) 
  {
   super();
   this._context = context;
   this.list = new ArrayList();
   this.objects=objects;
   Calendar calendar = Calendar.getInstance();
   setCurrentDayOfMonth(calendar.get(Calendar.DAY_OF_MONTH));
   setCurrentWeekDay(calendar.get(Calendar.DAY_OF_WEEK));

   // Print Month
   printMonth(month, year);
  }

  private String getMonthAsString(int i) 
  {
   return months[i];
  }

  private int getNumberOfDaysOfMonth(int i) 
  {
   return daysOfMonth[i];
  }

  public String getItem(int position) 
  {
   return list.get(position);
  }

  @Override

   int currentMonth = mm - 1;
   getMonthAsString(currentMonth);

   GregorianCalendar cal = new GregorianCalendar(yy, currentMonth, 1);
   if (currentMonth == 11)

   trailingSpaces = currentWeekDay;

   {

    {
     ++daysInMonth;
    }
    else if (mm == 3)
    {
     ++daysInPrevMonth;
    }
   }
