java - Android 处理日历的按钮

Question

我可以打开默认日历并保存事件。如果我单击日历中的“保存”按钮，我想调用一个方法。我正在使用这段代码:

CalendarUtolis.java

public void InsertAnEvent() {

    Calendar calendarEvent = Calendar.getInstance();
    Intent i = new Intent(Intent.ACTION_EDIT);
    i.setData(CalendarContract.Events.CONTENT_URI);
    i.putExtra("beginTime", calendarEvent.getTimeInMillis());
    i.putExtra("allDay", true);
    i.putExtra("rule", "FREQ=YEARLY");
    i.putExtra("endTime", calendarEvent.getTimeInMillis() + 60 * 60 * 1000);
    i.putExtra("title", "Eskuvo");

    activity.startActivityForResult(i, Activity.RESULT_CANCELED);
}

public void onActivityResult(int requestCode,int resultCode,Intent data){

    if(activity.RESULT_CANCELED==resultCode){
        Toast.makeText(activity, "No events added",Toast.LENGTH_LONG).show();
    }
    else{
        getNewEventId(activity.getContentResolver(),CalendarContract.Events.CONTENT_URI,activity);
    }
}

MainActivity.java

@Override
protected void onActivityResult(int requestCode,int resultCode,Intent data){
    super.onActivityResult(requestCode,resultCode,data);
    CalendarUtils u = new CalendarUtils(this);
    u.onActivityResult(0,resultCode,data);
}

问题是无论我保存与否，它总是显示“未添加事件”。你知道为什么吗？

尝试以下代码将事件添加到日历。

首先调用这个方法。

private void saveToCalender()
{

    try {

        long eventId=0;
        try {

            TGOption finalOption = options.get(0);
            long startMili = finalOption.getTimeInterval();
            long endMili = finalOption.getToTimeInterval();

            eventId=   addEventToCalender(this.getContentResolver(),this.project.getProjectName(),"","",1,startMili *1000,endMili*1000,true,false);



        }
        catch (Exception ex)
        {
            eventId=-1;
        }
        finally {

            if(eventId>0) {
           youract.this.finish();
            }
            else
            {
                Toast.makeText(this,this.getResources().getString(R.string.calender_error),Toast.LENGTH_LONG).show();
            }
        }



    }
    catch (Exception ex)
    {

    }


}

添加事件方法。

 /**
 * Add a new event into a native Google calendar. Add alert notification by setting <code>isRemind</code> as <code>true</code>.
 * @param cr - ContentResolver
 * @param title - Event title
 * @param addInfo - Event description
 * @param place - Event place
 * @param status -  <code>int</code> This information is sufficient for most entries: tentative (0), confirmed (1) or canceled (2):
 * @param startDate - <code>long</code> event start time in mls
 * @param isRemind - <code>boolean</code> need to remind about event before?
 * @param isMailService - <code>boolean</code>. Adding attendees to the meeting
 * @return <code>long</code> eventID

    ContentValues event = new ContentValues();

    long eventID=0;

    try {

        Uri eventUri = cr.insert(Uri.parse(eventUriStr), event);
         eventID = Long.parseLong(eventUri.getLastPathSegment());

    catch (Exception ex)

    if (isMailService) {
        String attendeuesesUriString = "content://com.android.calendar/attendees";
        /********* To add multiple attendees need to insert ContentValues multiple times ***********/
        ContentValues attendeesValues = new ContentValues();
        attendeesValues.put("event_id", eventID);

    return eventID;
