Using RecordStore in Java J2ME
- by me123
Hi,
I am currently doing some J2ME development. I am having a problem in that a user can add and remove elements to the record store, and if a record gets deleted, then that record is left empty and the others don't move up one. I'm trying to come up with a loop that will check if a record has anything in it (incase it has been deleted) and if it does then I want to add the contents of that record to a list.
My code is similar to as follows:
for (int i = 1; i <= rs.getNumRecords(); i++)
{
// Re-allocate if necessary
if (rs.getRecordSize(i) > recData.length)
recData = new byte[rs.getRecordSize(i)];
len = rs.getRecord(i, recData, 0);
st = new String(recData, 0, len);
System.out.println("Record #" + i + ": " + new String(recData, 0, len));
System.out.println("------------------------------");
if(st != null)
{
list.insert(i-1, st, null);
}
}
When it gets to rs.getRecordSize(i), I always get a "javax.microedition.rms.InvalidRecordIDException: error finding record". I know this is due to the record being empty but I can't think of a way to get around this problem.
Any help would be much appreciated.
Thanks in advance.
