• Changing Color with LinearLayout and TextView in Java (Android)

  - by Rob S.

  I'm a relatively new Android developer and I noticed what seems like an oddity to me that I'm hoping someone can explain. I have LinearLayout ll.

  Given a (doubly) linked list of objects (C++), I have an operation that I would like multithread, to perform on each object. The cost of the operation is not uniform for each object.

Sorry if this is a bad question. If you're unsure of what I'm asking about, its…

I have a calculation: xyz = ((1300 - [abc intValue])/6) + 100; xyz is defined as an NSInteger, abc is an NSString that is chosen via a UIPicker. I…

• Serializing persistent/functional data structures

  - by Rob

  Persistent data structures depend on the sharing of structure for efficiency. For an example, see here. How can I preserve the structure sharing when I serialize the data structures and write them to a file or database? If I just naively traverse the datastructures, I'll store the correct values, but I'll lose the…

• efficient sort with custom comparison, but no callback function

  - by rob

  I have a need for an efficient sort that doesn't have a callback, but is as customizable as using qsort(). What I want is for it to work like an iterator, where it continuously calls into the sort API in a loop until it is done, doing the comparison in the loop rather than off in a callback function. This…

• Is it possible to wrap an asynchronous event and its callback in a function that returns a boolean?

  - by Rob Flaherty

  I'm trying to write a simple test that creates an image element, checks the image attributes, and then returns true/false. The problem is that using the onload event makes the test asynchronous. On it own this isn't a problem (using a callback as I've done in the code below is easy), but what I can't…
