android - 以编程方式将事件添加到日历

Question

我在 Marshmellow 设备中使用以下代码以编程方式将事件添加到日历，但它不起作用。任何想法？我在日历应用程序中看不到此事件。

        long startMillis = 0;
        long endMillis = 0;
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date startDate = null, endDate = null;
        try{
            startDate = simpleDateFormat.parse("2017-05-01 01:30:00");
            startMillis = startDate.getTime();
            endDate = simpleDateFormat.parse("2017-05-01 03:30:00");
            endMillis = endDate.getTime();
        }catch (ParseException e){
            e.printStackTrace();
        }

        ContentResolver cr = this.getContentResolver();
        ContentValues values = new ContentValues();
        TimeZone timeZone = TimeZone.getDefault();
        values.put(CalendarContract.Events.DTSTART, startMillis);
        values.put(CalendarContract.Events.DTEND, endMillis);
        values.put(CalendarContract.Events.EVENT_TIMEZONE, timeZone.getID());
        values.put(CalendarContract.Events.TITLE, "Hello Title");
        values.put(CalendarContract.Events.DESCRIPTION, "Add events to Calendar");
        values.put(CalendarContract.Events.CALENDAR_ID, 879);
        Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

PS:如果只有一个 gmail 帐户与日历应用程序同步，它就可以工作。

Answer 1

我也找到了很多解决方案，最后我找到了解决方案并成功添加了日程表事件。

 Step -1 > Enable Google calnedar API From google console.
 Step - 2 > Add the permission in Androidmanifest.xml 

           <uses-permission android:name="android.permission.WRITE_CALENDAR"/> 

 Step =3 > Add library for checking Permissions in your  .gradle

          compile 'com.karumi:dexter:4.1.0'




    Dexter.withActivity(YoutActivityName.this)
                    .withPermission(Manifest.permission.WRITE_CALENDAR)
                    .withListener(new PermissionListener() 
                    {
                        @Override
                        public void onPermissionGranted(PermissionGrantedResponse response) {
                            try {

                                int calenderId = -1;
                                String calenderEmaillAddress = "sathishmicit2012@gmail.com";
                                String[] projection = new String[]{
                                        CalendarContract.Calendars._ID,

                                        new String[]{calenderEmaillAddress, calenderEmaillAddress,
                                                calenderEmaillAddress}, null);

                                if (cursor.moveToFirst()) {

                                    if (cursor.getString(1).equals(calenderEmaillAddress)) {

                                String title = "This is my demo test with alaram with 5 minutes";

                                cvEvent.put("calendar_id", calenderId);
