Я не мог понять, как это сделать в каждом файле.
ItemsDbAdapter:
public Cursor findAllGrouped(Date from, Date to) {
String where = KEY_STARTEDAT + " >= " + from.getTime() + " AND " + KEY_STARTEDAT + " <= "
+ to.getTime();
String[] columns = new String[] { KEY_ROWID, KEY_PROJECTID, KEY_DATE,
"sum(" + KEY_ENDEDAT + "-" + KEY_STARTEDAT + ") as hours" };
return _dbHelper.getDb().query(true, DATABASE_TABLE, columns, where, null,
KEY_DATE + ", " + KEY_PROJECTID, null, null, null);
}
