Question

我正在尝试创建一个Intent来创建Calendar活动。以下是代码：

public void onClickCalendarEntry(View view){
        Intent calendarIntent = new Intent(Intent.ACTION_INSERT);
        calendarIntent.setType("com.android.calendar/events");
        calendarIntent.putExtra(Events.TITLE, "Learn Android");
        calendarIntent.putExtra(Events.EVENT_LOCATION, "Home");
        calendarIntent.putExtra(Events.DESCRIPTION, "Learn activities");

        //Setting dates
        GregorianCalendar calDate = new GregorianCalendar(2012,12,2);
        calendarIntent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, 
                calDate.getTimeInMillis());
        calendarIntent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, 
                calDate.getTimeInMillis());


        Log.d(tag, "Before startActivity()");
        startActivity(calendarIntent);
        Log.d(tag, "Afte startActivity()");
    }

现在下面是AndroidManifest.exml摘录：

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

以下是我收到的错误消息：

任何人都可以帮我理解这里的问题是什么？感谢。

Answer 1

弗洛约之前的{p> "calendar/events"。

"com.android.calendar/events"后Froyo。

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.FROYO) {
    calendarIntent.setType("calendar/events");
} else {
    calendarIntent.setType("com.android.calendar/events");
}

Answer 2

最后问题解决了：

以下是我现在使用的代码：

Calendar cal = Calendar.getInstance();              
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", cal.getTimeInMillis());
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FREQ=DAILY");
intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
intent.putExtra("title", "A Test Event from android app");
startActivity(intent);

感谢所有人的帮助。
