I used the same source in my app (pretty sure), and there is a block of code:

protected void onListItemClick(ListView l, View v, int position, long id) {
    if (file.isDirectory()) {
        selectButton.setEnabled(false);
        if (file.canRead()) {
            lastPositions.put(currentPath, position);
            getDir(path.get(position));
        } else {
            new AlertDialog.Builder(this)
                    .setIcon(R.drawable.icon)
                    .setTitle(
                            "[" + file.getName() + "] "
                                    + getText(R.string.cant_read_folder))
                    .setPositiveButton("OK",
                            new DialogInterface.OnClickListener() {

                                @Override
                                public void onClick(DialogInterface dialog,
                                        int which) {

                                }
                            }).show();
        }
    } else {
        selectedFile = file;
        v.setSelected(true);
        selectButton.setEnabled(true);
    }
}

You just have to edit how it handle's if (file.isDirectory()). I would recommend declaring a boolean value in your Activity which you change to true if the file is a directory and it is already false. Then if said value is true, then traverse the directory. Also when you change said value to true, you would need to call selectButton.setEnabled(true). This would be quite a bit less complicated than making your own code, I would say.
