Similar to android day calendar and event add & display in day view.

If you

Answer 1

you can use google calendar in order to display your new calendar and over here you can create your own events. Below is the class for creating a new calendar.

public class CalendarMapper {
    private static final String ACCOUNT_NAME = "private";
    private static final String INT_NAME_PREFIX = "priv";

    @SuppressLint("NewApi")
    private static Uri buildCalUri() {
        return CalendarContract.Calendars.CONTENT_URI
                .buildUpon()
                .appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true")
                .appendQueryParameter(Calendars.ACCOUNT_NAME, ACCOUNT_NAME)
                .appendQueryParameter(Calendars.ACCOUNT_TYPE, CalendarContract.ACCOUNT_TYPE_LOCAL)
                .build();
    }

    private static ContentValues buildContentValues(Calendar calendar) {
        String dispName = "TUM3";  //Calendar.getName() returns a String
        String intName = INT_NAME_PREFIX + dispName;
        final ContentValues cv = new ContentValues();
        cv.put(Calendars.ACCOUNT_NAME, ACCOUNT_NAME);
        cv.put(Calendars.ACCOUNT_TYPE, CalendarContract.ACCOUNT_TYPE_LOCAL);
        cv.put(Calendars.NAME, intName);
        cv.put(Calendars.CALENDAR_DISPLAY_NAME, dispName);
        //cv.put(Calendars.CALENDAR_COLOR, calendar.getColor());  //Calendar.getColor() returns int
        cv.put(Calendars.CALENDAR_ACCESS_LEVEL, Calendars.CAL_ACCESS_OWNER);
        cv.put(Calendars.OWNER_ACCOUNT, ACCOUNT_NAME);
        cv.put(Calendars.VISIBLE, 1);
        cv.put(Calendars.SYNC_EVENTS, 1);

        return cv;
    }

    @SuppressWarnings("deprecation")
    public static Uri addCalendar(Calendar calendar, ContentResolver cr) {
        if (calendar == null)
            throw new IllegalArgumentException();

        final ContentValues cv = buildContentValues(calendar);
        Uri calUri = buildCalUri();
        Uri cancelUri=cr.insert(calUri, cv);
        return cancelUri;
    }

}

In the main activity you can call add calendar to create a calendar and add an event into this calendar.

Uri cancelUri;
 @SuppressLint("NewApi")
    public void displayCal(View view){
           ContentResolver crv = getContentResolver();

           Calendar calendar = Calendar.getInstance();
           cancelUri= CalendarMapper.addCalendar(calendar, crv);

           long calID=2; //ID of the newly created calendar. You can query the calendars table to get the ID of your calendar
           long endMillis = 10100;     
           Calendar beginTime = Calendar.getInstance();
           beginTime.set(2012, 9, 14, 7, 30);
           long startMillis = beginTime.getTimeInMillis();
           Calendar endTime = Calendar.getInstance();
           endTime.set(2012, 9, 14, 8, 45);
           endMillis = endTime.getTimeInMillis();

           ContentResolver cr = getContentResolver();
           ContentValues values2 = new ContentValues();
           values2.put(Events.DTSTART, startMillis);
           values2.put(Events.DTEND, endMillis);
           values2.put(Events.TITLE, "Jazzercise");
           values2.put(Events.DESCRIPTION, "Group workout");
           values2.put(Events.CALENDAR_ID, calID);

           values2.put(Events.EVENT_TIMEZONE, "America/Los_Angeles");
           Uri uri = cr.insert(Events.CONTENT_URI, values2);

           Uri.Builder builder = CalendarContract.CONTENT_URI.buildUpon();
           builder.appendPath("time");

           ContentUris.appendId(builder, startMillis);
           Intent intent = new Intent(Intent.ACTION_VIEW)
               .setData(builder.build());
           startActivity(intent);
    }

In order to delete this calendar, you can do it like below

public void delCal(View view){
         ContentResolver crv = getContentResolver();
         crv.delete(cancelUri, null, null);
    }
