Answer 1

This worked for me :

    final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.AppCompatAlertDialogStyle);
    builder.setCancelable(true);
    builder.setTitle(title);
    builder.setMessage(message);

    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });


    final AlertDialog dialog = builder.create();
    dialog.show(); //show() should be called before dialog.getButton().


    final Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
    LinearLayout.LayoutParams positiveButtonLL = (LinearLayout.LayoutParams) positiveButton.getLayoutParams();
    positiveButtonLL.gravity = Gravity.CENTER;
    positiveButton.setLayoutParams(positiveButtonLL);
