Question

I have to get a part of my content provider query in a String[] format. Currently I use:

        String[] selectionArgs = {"",""};
    selectionArgs[0] = Integer.toString(routeScheduleID);
    selectionArgs[1] = runDate.toString();

But in this case I have an unknown number of elements.

How can I change the number at runtime (or use something like an Array and convert back to String[]. Is this possible?

You can use List<String> to get your data and then get the array out of it:

List<String> lst = new ArrayList<String>();
lst.add(Integer.toString(routeScheduleID);
lst.add(runDate.toString());
lst.add(...);
...

String[] selectionArgs = lst.toArray(new String[lst.size()]);
