if i follow your question, than you can retrieve the list of file with .jpg extension run a loop on list and show in imageview.

    File root = new File("/sdcard/MyCollection");
    final String files[] = root.list(imageFilter);
    FilenameFilter imageFilter = new FilenameFilter() {
        File f;
        public boolean accept(File dir, String name) {
        if(name.endsWith(".jpg")) {
                return true;
            }
            f = new File(dir.getAbsolutePath()+"/"+name);

            return f.isDirectory();
        }
    };

files will return an array of files.You can loop on it.
