java - Android - Output List of events from Google calendar

I would ask You for a help. Now I am writing an app, which takes current events from Google calendars. But problem is there, when I'm trying to output events from more than one calendar. I know, that I'm doing something wrong, but really, can't get in the problem..

    public class Main extends Activity {


        //TextView mInfo;
        TextView mEvents;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);     
            setContentView(R.layout.main);
            //mInfo = (TextView)findViewById(R.id.info);
            mEvents = (TextView)findViewById(R.id.events);


            String[] calendarName = {"Calendar1", "Calendar2", "Calendar3", "Calendar4", "Calendar5"};

            readCalendars(calendarName);
        }

        private void readCalendars(String[] calendarName)
        {
            String[] projection =
                    new String[]{

                            CalendarContract.Calendars._ID,
                            CalendarContract.Calendars.NAME,
                            CalendarContract.Calendars.ACCOUNT_NAME,
                            CalendarContract.Calendars.ACCOUNT_TYPE};
            Cursor calCursor =
                    getContentResolver().
                            query(CalendarContract.Calendars.CONTENT_URI,
                                    projection,
                                    CalendarContract.Calendars.VISIBLE + " = 1",
                                    null,

                                    CalendarContract.Calendars._ID + " ASC");
            long calId = -1;
            //String calendarAccount = "";
            for(int i = 0; i  0)
                {
                    if(cursor.moveToFirst())
                    {
                        do
                        {
                            long eventId = cursor.getLong(3);

                            events += getEventInfo(eventId,cursor.getLong(1),cursor.getLong(2),cursor.getString(4),cursor.getString(5),cursor.getString(6)) + "\n";
                        } while(cursor.moveToNext());
                    }
                }
                mEvents.setText(events);
            }
        }

        @SuppressLint("SimpleDateFormat")
        private String getEventInfo(long eventId,long startTime, long endTime,String description, String location,String title)

        {
                String eventInfo = "";
                {
                    DateFormat df = new SimpleDateFormat("HH:mm");
                    String start = df.format( new Date(startTime));
                    String end = df.format( new Date(endTime));
                    eventInfo = start + "-" + end + " Class: "+ location + "\nLecture: " + title + "\nLecturer: " + description;
                }
            return eventInfo;
        }

    }

Tried to output all events with loop, but does not helps. If I pass in calendarName[i], where i is one of existing calendars, I get output of calendar, which I asked for, but that's only one calendar, but for example, I need to output 5 calendars.

Tried to do anything with ListView - failure again.

Hope, You would help with this problem or help somehow how to resolve it..
