Question

我正在创建一个访问Android日历的应用程序并创建一个事件。

它在android 2.3中运行良好，但在4.0＆gt;它不会创建事件并抛出异常

我不知道我做错了什么，这是我的代码：

    public void addReminder() {

    Calendar beginTime = Calendar.getInstance();

    long startMillis = beginTime.getTimeInMillis();

    long endMillis = beginTime.getTimeInMillis() + 60 * 60 * 1000;


    String eventUriString = "content://com.android.calendar/events";
    ContentValues eventValues = new ContentValues();

    eventValues.put(Events.CALENDAR_ID, 1);
    eventValues.put(Events.TITLE, "Test");
    eventValues.put(Events.DESCRIPTION, "Test");
    eventValues.put(Events.EVENT_TIMEZONE, "Montevideo");
    eventValues.put(Events.DTSTART, startMillis);
    eventValues.put(Events.DTEND, endMillis);

    eventValues.put("eventStatus", 1);
    eventValues.put(Events.HAS_ALARM, 1);


        Uri eventUri = getContentResolver().insert(
                Uri.parse(eventUriString), eventValues);
        long eventID = Long.parseLong(eventUri.getLastPathSegment());

        String reminderUriString = "content://com.android.calendar/reminders";
        ContentValues reminderValues = new ContentValues();

        reminderValues.put("event_id", eventID);
        reminderValues.put("minutes", 1);
        reminderValues.put("method", 1);



        Uri reminderUri = getContentResolver().insert(
                Uri.parse(reminderUriString), reminderValues);


}

在Android 4.0＆gt;这就是我得到的：

这是我的权限：

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

它可能是什么？

http://developer.android.com/guide/topics/providers/calendar-provider.html#intent-insert 分别用CalendarContract.EXTRA_EVENT_BEGIN_TIME，CalendarContract.EXTRA_EVENT_END_TIME替换Events.DTSTART，Events.DTEND。

Calendar beginTime = Calendar.getInstance();
beginTime.set(2012, 0, 19, 7, 30);
Calendar endTime = Calendar.getInstance();
endTime.set(2012, 0, 19, 8, 30);
Intent intent = new Intent(Intent.ACTION_INSERT)
        .setData(Events.CONTENT_URI)
        .putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, beginTime.getTimeInMillis())
        .putExtra(CalendarContract.EXTRA_EVENT_END_TIME, endTime.getTimeInMillis())
        .putExtra(Events.TITLE, "Yoga")
        .putExtra(Events.DESCRIPTION, "Group class")
        .putExtra(Events.EVENT_LOCATION, "The gym")
        .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY)
        .putExtra(Intent.EXTRA_EMAIL, "rowan@example.com,trevor@example.com");
startActivity(intent);

Answer 2

检查您创建的事件的日历ID是否指向现有的已启用日历（而不仅仅是eventValues.put（Events.CALENDAR_ID，1）;）。尝试添加指向事件的提醒时，我遇到了这样的异常（reminderValues.put（“event_id”，eventID）;），这是在与现有日历无关的calendar_id中添加的。可能有一些检查......

无法在Android 4.0上设置日历事件＆gt;
