Caldroid * can be used as embedded fragment, or as dialog fragment. <br/> * <br/> * Caldroid fragment includes 4 main parts:<br/> * <br/> * 1) Month title view: show the month and year (e.g MARCH, 2013) <br/> * <br/> * 2) Navigation arrows: to navigate to next month or previous month <br/> * <br/> * 3) Weekday gridview: contains only 1 row and 7 columns. To display * "SUN, MON, TUE, WED, THU, FRI, SAT" <br/> * <br/> * 4) An infinite view pager that allow user to swipe left/right to change * month. This library is taken from * https://github.com/antonyt/InfiniteViewPager <br/> * <br/> * This infinite view pager recycles 4 fragment, each fragment contains a grid * view with 7 columns to display the dates in month. Whenever user swipes * different screen, the date grid views are updated. <br/> * <br/> * Caldroid fragment supports setting min/max date, selecting dates in a range, * setting disabled dates, highlighting today. It includes convenient methods to * work with date and string, enable or disable the navigation arrows. User can * also swipe left/right to change months.<br/> * <br/> * Caldroid code is simple and clean partly because of powerful JODA DateTime * library! * * @author thomasdao * */ @SuppressLint("DefaultLocale") public class CaldroidFragment extends DialogFragment { public String TAG = "CaldroidFragment"; /** * Weekday conventions */ public static int SUNDAY = 1; public static int MONDAY = 2; public static int TUESDAY = 3; public static int WEDNESDAY = 4; public static int THURSDAY = 5; public static int FRIDAY = 6; public static int SATURDAY = 7; /** * Flags to display month */ private static final int MONTH_YEAR_FLAG = DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_NO_MONTH_DAY | DateUtils.FORMAT_SHOW_YEAR; /** * First day of month time */ private Time firstMonthTime = new Time(); /** * Reuse formatter to print "MMMM yyyy" format */ private final StringBuilder monthYearStringBuilder = new StringBuilder(50); private Formatter monthYearFormatter = new Formatter( monthYearStringBuilder, Locale.getDefault()); /** * To customize the selected background drawable and text color */ public static int selectedBackgroundDrawable = -1; public static int selectedTextColor = Color.BLACK; public final static int NUMBER_OF_PAGES = 4; /** * To customize the disabled background drawable and text color */ public static int disabledBackgroundDrawable = -1; public static int disabledTextColor = Color.GRAY; /** * Caldroid view components */ private Button leftArrowButton; private Button rightArrowButton; private TextView monthTitleTextView; private TextView hijrimonthTitleTextView; private GridView weekdayGridView; private InfiniteViewPager dateViewPager; private DatePageChangeListener pageChangeListener; private ArrayList<DateGridFragment> fragments; /** * Initial params key */ public final static String DIALOG_TITLE = "dialogTitle"; public final static String MONTH = "month"; public final static String YEAR = "year"; public final static String SHOW_NAVIGATION_ARROWS = "showNavigationArrows"; public final static String DISABLE_DATES = "disableDates"; public final static String SELECTED_DATES = "selectedDates"; public final static String MIN_DATE = "minDate"; public final static String MAX_DATE = "maxDate"; public final static String ENABLE_SWIPE = "enableSwipe"; public final static String START_DAY_OF_WEEK = "startDayOfWeek"; public final static String SIX_WEEKS_IN_CALENDAR = "sixWeeksInCalendar"; public final static String ENABLE_CLICK_ON_DISABLED_DATES = "enableClickOnDisabledDates"; /** * For internal use */ public final static String _MIN_DATE_TIME = "_minDateTime"; public final static String _MAX_DATE_TIME = "_maxDateTime"; public final static String _BACKGROUND_FOR_DATETIME_MAP = "_backgroundForDateTimeMap"; public final static String _TEXT_COLOR_FOR_DATETIME_MAP = "_textColorForDateTimeMap"; /** * Initial data */ protected String dialogTitle; protected int month = -1; protected int year = -1; protected ArrayList<DateTime> disableDates = new ArrayList<DateTime>(); protected ArrayList<DateTime> selectedDates = new ArrayList<DateTime>(); protected DateTime minDateTime; protected DateTime maxDateTime; protected ArrayList<DateTime> dateInMonthsList; /** * caldroidData belongs to Caldroid */ protected HashMap<String, Object> caldroidData = new HashMap<String, Object>(); /** * extraData belongs to client */ protected HashMap<String, Object> extraData = new HashMap<String, Object>(); /** * backgroundForDateMap holds background resource for each date */ protected HashMap<DateTime, Integer> backgroundForDateTimeMap = new HashMap<DateTime, Integer>(); /** * textColorForDateMap holds color for text for each date */ protected HashMap<DateTime, Integer> textColorForDateTimeMap = new HashMap<DateTime, Integer>();; /** * First column of calendar is Sunday */ protected int startDayOfWeek = SUNDAY; /** * A calendar height is not fixed, it may have 5 or 6 rows.
