animazione menu

Ho trovato in rete il codice funzionante di un menu slider.
In tale codice però i layout vengono generati all'interno del codice stesso, qualcuno potrebbe aiutami nel configurarlo per un file layout in *.xml?
Codice:
Codice (Java): [Seleziona]

    private boolean Menu_Displayed=false;

    @Override

        super.onCreate(savedInstanceState);

        Display display = getWindowManager().getDefaultDisplay();
        final int width = display.getWidth();

        // menu:
        LinearLayout li_menu = new LinearLayout(this);
        li_menu.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));  
        li_menu.setOrientation(1);//1 is vertical
        li_menu.setBackgroundColor(Color.GREEN);

        Button btn1 = new Button(this);
        btn1.setText("button 1");
        btn1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));  

        li_menu.addView(btn1);

        //body:
        final HorizontalScrollView hsv = new HorizontalScrollView(this){
            @Override
            // do not let hsv consume the click itself. Then the view under the hsv will also consume the click
            //so that the menu will be clicked
