Using Caldroid whit SQLite

[Poreis]

So I am using a DataBase whit dates , and I have a code that retrieves the maxID of that database(number of dates) and then , I have a for loop that goes trough the database and selects a date (String) and parses it in to a date and the sets the background for that date on the calendar . The problem is that its not setting the background for blue.

The code that gets the maxID and the Dates from the database :
` public int getLastId() {
String query = "SELECT MAX(id) AS max_id FROM " + TABLE_NAME;
Cursor cursor = database.rawQuery(query, null);
int id = 0;
if (cursor.moveToFirst())
{
do
{
id = cursor.getInt(0);
} while(cursor.moveToNext());

    }
    cursor.close();
    return id;

}

public String getDates(int numero){
    String date = "";
    String last_query = "SELECT " + COL_4  + " FROM " + TABLE_NAME  + " WHERE " + COL_1 + " = '" + numero + "'";
    Cursor c = database.rawQuery(last_query, null);
    if (c != null && c.moveToFirst())
    {
        date = c.getString(c.getColumnIndex("DIA")); // Return Value
    }
    c.close();
    return date;
}

}`

The code that uses those methods and setTHEbackgroundColor for each of those dates: ` public void addToCalendar(){

    myDB = CustomApplication.getDatabaseHelper();
    ColorDrawable blue = new ColorDrawable(Color.BLUE);
    for(int i=0;i == myDB.getLastId();i++){
        String dt = myDB.getDates(i);
        java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("dd-MM-yyyy");
        Date teste = null;
        try {
            teste = sdf.parse(dt);
            caldroidFragment.setBackgroundDrawableForDate(blue,teste);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}
