Android 4.0中日历的位置是哪个？

Question

当我在Nexus S上开发API为7的APP时,在我的日历上创建新事件没有问题.

我使用该代码获取手机日历的位置:

cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null);

当我将nexus S更新为Android ICS 4.0时出现问题.没有改变任何代码我犯了一个错误.在logcat上,我可以读到:

• 没有这样的列:displayname,db =/data/data/com.android.providers.calendar/databases/calendar.db

当然游标是null.也许日历数据库有任何变化？所以,我想知道如何在Android 4.0上创建开发API 7应用程序的新日历事件

谢谢 ;)

在Android 4.0中,日历与Android 2.3中的Uri相同.所以我附上我的代码以防其他人遇到同样的问题.

    public void addToCalendar(Context ctx, final String title, final String comment, final long dtstart, final long dtend) {


    final ContentResolver cr = ctx.getContentResolver();
    Cursor cursor ;

    cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id","calendar_displayName" }, null, null, null);

    /*if (Integer.parseInt(Build.VERSION.SDK) == 8 )
        cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null);
    */

    //Get all the calendar ids and name available in the phone
    if ( cursor.moveToFirst() ) {
        final String[] calNames = new String[cursor.getCount()];
        final int[] calIds = new int[cursor.getCount()];
        for (int i = 0; i < calNames.length; i++) {
            calIds[i] = cursor.getInt(0);
            calNames[i] = cursor.getString(1);
            cursor.moveToNext();
        }

        //Creation of a new event in calendar whose position is 0 on the phone
        ContentValues cv = new ContentValues();
        cv.put("calendar_id", calIds[0]);
        cv.put("title", title);
        cv.put("dtstart", dtstart );
        cv.put("dtend", dtend);
        cv.put("eventTimezone","Spain");
        cv.put("description", comment );

        //Insertion on the events of the calendar
        cr.insert(Uri.parse("content://com.android.calendar/events"), cv);

        /*Uri newEvent ;
        if (Integer.parseInt(Build.VERSION.SDK) == 8 )
            newEvent = cr.insert(Uri.parse("content://com.android.calendar/events"), cv);
        */

        finish();

    }
    cursor.close();

}
