 I'm new to Java/Android, can anyone recommend a tutorial on android
that introduces reading and writing flat files?

ps, if this is a double post, sorry, but I posted several hours ago
and it seems it never went through.

Basic file input / output tutorial

 I'm not aware of a tutorial, but it's pretty easy - here's some code that
reads in a file.  Check out the File and File*Stream classes.

        String path = "/data/data/com.company.app/files/foo.jpg";
        File f = new File (path);
        if (f.exists() && f.canRead ())
        {
            try
            {
                FileInputStream is = new FileInputStream (f);
                int size = is.available();
                contents = new byte[size];
                int got = is.read (contents);
                if (got != size)
                {
                    Log.e ("File", f.getName () + ": expected " + size + ",
got " + got + " bytes.");
                    bm = null;
                }
                else
                    bm = BitmapFactory.decodeByteArray (contents, 0, size);
            }
            catch (Exception e)
            {
                Log.e ("FileSave", e.toString());
            }

1. ListView: Disable Focus Highlight

Hi,

I've set the row (view) being used in a ListView as non-focusable
along with non-clickable and have set the listview's focusable flag to
false as well. However, I still get the yellow highlight when I use
the scroll-ball on my device. How can I disable the yellow highlight
and use my own special view/color instead upon focus?

Any help would be much appreciated.

Thanks
