Here's an example:

  private Dialog mDialog;

    public void openDialog(){
        mDialog = new Dialog(this);
        //vamos remover o titulo da Dialog
        mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //vamos carregar o xml personalizado
        mDialog.setContentView(R.layout.dialog);
        //DEixamos transparente
        mDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
        // não permitimos fechar esta dialog
        mDialog.setCancelable(false);
        //temos a instancia do ProgressBar!
        final ProgressBar progressBar = ProgressBar.class.cast(mDialog.findViewById(R.id.progressBar));


        mDialog.show();

               // mDialog.dismiss(); -> para fechar a dialog

    }
}
