Justify AlertDialog text

I have a class of a generic AlertDialog in a DialogFragment, which works fine. I use it for example to pop-up an "About" dialog.

Problem is the text in the dialog is not justified so it doesn't look very nice. Is there a way I can justify the text? Meaning, align it to both right and left sides?

This is the relevant function in my code:

@Override
public AlertDialog onCreateDialog(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Resources res = getActivity().getResources();
    String title = getArguments().getString("title");
    String message = getArguments().getString("message");
    String yesButton = getArguments().getString("yes_button");
    String noButton = getArguments().getString("no_button");
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), android.R.style.Theme_Material_Dialog_Alert);
    if (!noButton.equals(""))
        builder.setNegativeButton(noButton, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                mCancel.run();
            }
        });
    builder.setIcon(R.mipmap.my_launcher)
            .setTitle(title.equals("") ? res.getString(R.string.app_name) : title)
            .setMessage(message)
            .setPositiveButton(yesButton, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    mConfirm.run();
                }
            });
    AlertDialog dialog = builder.create();
    dialog.show();
    // text MATCH_PARENT
    TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
    LinearLayout.LayoutParams messageViewLL = (LinearLayout.LayoutParams) messageView.getLayoutParams();
    messageViewLL.width = ViewGroup.LayoutParams.MATCH_PARENT;

    // If only positive button, center it.
    if (noButton.equals("")) {
        Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
        LinearLayout.LayoutParams positiveButtonLL = (LinearLayout.LayoutParams) positiveButton.getLayoutParams();
        positiveButtonLL.width = ViewGroup.LayoutParams.MATCH_PARENT;
    }
    return dialog;
}

If you mean align title/message text, then instead of .setTitle(String) use .setCustomTitle(View) and instead of .setMessage(String) use .setView(View), you can just align text or set padding:

    TextView titleView = new TextView(context);
    titleView.setText(title.equals("") ? res.getString(R.string.app_name) : title);
    titleView.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_END);

    TextView messageView = new TextView(context);
    messageView.setText(message);
    messageView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
    messageView.setPadding(20, 20, 20, 20);
            // your code

    builder.setIcon(R.mipmap.my_launcher)
            .setCustomTitle(titleView)
            .setView(messageView)
            .setPositiveButton(yesButton, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    mConfirm.run();
                }
            });
