如何在android中以编程方式集成电子邮件日历事件条目？

<uses-permission android:name="com.android.email.permission.READ_PERMISSION" />
<uses-permission android:name="com.android.email.permission.WRITE_PERMISSION" />

String[] projection = new String[] { Email.CONTENT_URI.toString() };
Cursor cursor = getContentResolver().query(Email.CONTENT_URI, projection, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
    do {
        // 处理电子邮件账户
        String accountName = cursor.getString(cursor.getColumnIndex(Email.DATA));
        // ...
    } while (cursor.moveToNext());
}

String[] projection = new String[] { Email._ID, Email.SUBJECT, Email.DATE };
String selection = Email.ACCOUNT_NAME + "=?";
String[] selectionArgs = new String[] { accountName };
Cursor cursor = getContentResolver().query(Email.CONTENT_URI, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
    do {
        // 处理电子邮件
        long emailId = cursor.getLong(cursor.getColumnIndex(Email._ID));
        String subject = cursor.getString(cursor.getColumnIndex(Email.SUBJECT));
        // ...
    } while (cursor.moveToNext());
}

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

String[] projection = new String[] { CalendarContract.Calendars._ID, CalendarContract.Calendars.NAME };
Cursor cursor = getContentResolver().query(CalendarContract.Calendars.CONTENT_URI, projection, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
    do {
        // 处理日历
        long calendarId = cursor.getLong(cursor.getColumnIndex(CalendarContract.Calendars._ID));
        String calendarName = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.NAME));
        // ...
    } while (cursor.moveToNext());
}

ContentValues values = new ContentValues();
values.put(CalendarContract.Events.CALENDAR_ID, calendarId);
values.put(CalendarContract.Events.TITLE, "My Event");
values.put(CalendarContract.Events.DESCRIPTION, "Event Description");
values.put(CalendarContract.Events.EVENT_LOCATION, "Event Location");
// 设置事件开始时间和结束时间
values.put(CalendarContract.Events.DTSTART, startTimeMillis);
values.put(CalendarContract.Events.DTEND, endTimeMillis);
// 设置事件时区
values.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());

Uri uri = getContentResolver().insert(CalendarContract.Events.CONTENT_URI, values);
