Centering the message of a DialogFragment without a custom layout file

I'm trying to add a center gravity to the message of a dialog fragment without having a separate XML file for a custom layout. I've tried getting the TextView and setting the gravity of that, but it doesn't seem to do anything:

    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the Builder class for convenient dialog construction
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("Replace current sound");
        builder.setMessage("Choose a mp3 or ogg file or restore the default sound.\nThe current sound is:\n"+currentSound)
               .setPositiveButton("Choose new sound", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                    // This is the Choose File dialog (uses aFileDialog library)
                    // to get the file replacement
                    FileChooserDialog dialog1 = new FileChooserDialog(context);
                    dialog1.show();
                    dialog1.addListener(new OnFileSelectedListener() {
                        @Override
                        public void onFileSelected(Dialog source, File file) {
                            // TODO Auto-generated method stub
                            source.hide();
                            Log.e("App Debugging", file.getAbsolutePath());
                            String fileReplacement = file.getAbsolutePath();

                        }

                        @Override
                        public void onFileSelected(Dialog source, File folder,
                                String name) {
                            // TODO Auto-generated method stub

                        }
                    });
                   }
               })
               .setNegativeButton("Restore default", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {

                   }
               });
        AlertDialog dialog = builder.show(); 
        TextView messageText = TextView)dialog.findViewById(android.R.id.message);
        messageText.setGravity(Gravity.CENTER);
        // Create the AlertDialog object and return it
        return builder.create();
    }

EDIT: Here are my findings so far: I can get it to work if I add another builder.show(); call after setting the messageText gravity, but that leads to another dialog popping up right after closing the first one.

To solve this problem...

You only have to return your dialog

AlertDialog dialog = builder.show(); 
TextView messageText = (TextView)dialog.findViewById(android.R.id.message);
messageText.setGravity(Gravity.CENTER);
return dialog;

Could you try like this

AlertDialog dialog = builder.show(); 
TextView messageText = (TextView)dialog.findViewById(android.R.id.message); 
FrameLayout.LayoutParams p = (FrameLayout.LayoutParams) messageText.getLayoutParams();
p.gravity = Gravity.CENTER;
messageText.setLayoutParams(p);
