Answer 1

You can set the positive, negative and neutral buttons, hide both the positive and neutral buttons, and put the negative button where the neutral button is supposed to be(center) by using LayoutParams.

in onCreateView:

dialog = builder.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        })
                 .setPositiveButton(R.string.go_on, new DialogInterface.OnClickListener() {
                     @Override
                     public void onClick(DialogInterface dialog, int which) {

                     }
                 })
                 .setNeutralButton(R.string.do_nothing, new DialogInterface.OnClickListener() {
                     @Override
                     public void onClick(DialogInterface dialog, int which) {

                     }
                 })
                 .create();

in onStart():

 super.onStart();

    final Button positiveButton = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
   positiveButton.setVisibility(View.INVISIBLE);
   final Button neutralButton = dialog.getButton(AlertDialog.BUTTON_NEUTRAL);
   neutralButton.setVisibility(View.INVISIBLE);
   final Button negativeButton = dialog.getButton(AlertDialog.BUTTON_NEGATIVE);
   negativeButton.setLayoutParams(neutralButton.getLayoutParams());
