How to get Calendar Column names from DataBase in android 2.1..?

here is my code.. which works fine in android 1.6.. but throws IllegalArguementException in 2.1 devices.

Uri calendars = Uri.parse("content://com.android.calendar/calendars");
        Cursor managedCursor =   managedQuery(calendars, null,null, null, null);


    if (managedCursor.moveToFirst()) 
    {   int i = managedCursor.getColumnCount();
    for (int j = 0; j &开发者_JAVA百科lt; managedCursor.getColumnCount(); j++) {

        Log.d("#$$$$$$$$############","##"+managedCursor.getColumnName(j));

    }
        Log.d("################@@@@@@@@",String.valueOf(i));

        int nameColumn = managedCursor.getColumnIndex("name");  
        int idColumn = managedCursor.getColumnIndex("_id"); 
        do 
        {    
            calName = managedCursor.getString(1);    
            calId = managedCursor.getString(0); 
            } while (managedCursor.moveToNext());
    }
    ContentValues event = new ContentValues();
    event.put("calendar_id", calId);
    event.put("title", "Event Title");
    event.put("description", "Event Desc");
    event.put("eventLocation", "Event Location");

    event.put("hasAlarm", 1); 
     Uri eventsUri = Uri.parse("content://com.android.calendar/calendars");  
     Uri url = getContentResolver().insert(eventsUri, event);

and the logCat has this...

Thanks in advance..

Use the following code for android2.1

Cursor cursor = getContentResolver().query(Uri.parse("content://calendar/calendars"),
                        new String[] { "_id", "displayName" }, "selected=1", null, null);
        if (cursor != null && cursor.moveToFirst()) {
             String[] calNames = new String[cursor.getCount()];
             int[] calIds = new int[cursor.getCount()];
             for (int i = 0; i < calNames.length; i++) {
                  // retrieve the calendar names and ids
                  // at this stage you can print out the display names to get an idea of what calendars the user has
                  calIds[i] = cursor.getInt(0);
                  calNames[i] = cursor.getString(1);
                  cursor.moveToNext();
              }
              cursor.close();
              if (calIds.length > 0) {
                   // we're safe here to do any further work
              }


     // grab calendar id from above
        int cal_id = calIds[0];

        // set the content value
        ContentValues cv = new ContentValues();

        // make sure you add it to the right calendar
        cv.put("calendar_id", cal_id);

        // set the title of the event
        cv.put("title", "jwei's birthday");

        // set the description of the event
        cv.put("description", "Time to celebrate jwei's birthday.");

        // set the event's physical location
        cv.put("eventLocation", "Palo Alto, CA");

        // set the start and end time
        // note: you're going to need to convert the desired date into milliseconds
        cv.put("dtstart", System.currentTimeMillis());
        cv.put("dtend", System.currentTimeMillis() + DateUtils.DAY_IN_MILLIS);

        // let the calendar know whether this event goes on all day or not
        // true = 1, false = 0
        cv.put("allDay", 1);

        // let the calendar know whether an alarm should go off for this event
        cv.put("hasAlarm", 1);

        // once desired fields are set, insert it into the table
        getContentResolver().insert(Uri.parse("content://calendar/events"), cv);
        }

because on line event.put("calendar_id", calId); callId should be int

i have these code for that

private void addToCalendar(Context ctx, final String title, final long dtstart, final long dtend) {
    final ContentResolver cr = ctx.getContentResolver();
    Cursor cursor ;
    if (Integer.parseInt(Build.VERSION.SDK) == 8 )
        cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null);
    else
        cursor = cr.query(Uri.parse("content://calendar/calendars"), new String[]{ "_id", "displayname" }, null, null, null);
    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();
        }

        AlertDialog.Builder builder = new AlertDialog.Builder(ctx);
        builder.setSingleChoiceItems(calNames, -1, new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                ContentValues cv = new ContentValues();
                cv.put("calendar_id", calIds[which]);
                cv.put("title", title);
                cv.put("dtstart", dtstart );
                cv.put("hasAlarm", 1);
                cv.put("dtend", dtstart);

instead of "displayName" use "calendar_displayName"

Now check and let us know..

happy coding!
