Android Calender提醒事件问题

Question

hello everyone I am a newbie here but I dont care if you people like it or not......... but I do not understand the way this site work.................

If I ask any question that has already been asked i get negative points..... and luckily if I find something useful.. the problem is then... I can not add my comments to that post to clarify the answer for me... for instance i found the following link useful for me

Put reminder in real calendar on the phone?

In that code the user have used the following line

Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");

I don't understand what should I do because Uri.parse() takes a string argument but here he uses an activity as a argument in

getCalendarUriBase(Activity act)

I would not have asked this question if I would've allowed to add my comments into that post

I hope you can understand the my point.... and for full code please visit the above link

Answer 1

It is strange that you didn't understand that answer.

getCalendarUriBase returns a String, its implementation is in that answer.

I copypaste it here for you

private String getCalendarUriBase(Activity act) {

                String calendarUriBase = null;
                Uri calendars = Uri.parse("content://calendar/calendars");
                Cursor managedCursor = null;
                try {
                    managedCursor = act.managedQuery(calendars, null, null, null, null);
                } catch (Exception e) {
                }
                if (managedCursor != null) {
                    calendarUriBase = "content://calendar/";
                } else {
                    calendars = Uri.parse("content://com.android.calendar/calendars");
                    try {
                        managedCursor = act.managedQuery(calendars, null, null, null, null);
                    } catch (Exception e) {
                    }
                    if (managedCursor != null) {
                        calendarUriBase = "content://com.android.calendar/";
                    }
                }
                return calendarUriBase;

Answer 2

imho,

getCalendarUriBase(this) + "events"
=
getCalendarUriBase(this).toString() + "events"

String concatenation?
