почему пункт меню не появляется

Я попытался создать независимый код, чтобы проверить, появится ли меню и появилось ли оно в других программах, но в этом коде оно не отображается, в чем может быть проблема? 

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    dp = new Panel(this);
    dp.setOnTouchListener(this);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    mPaint = new Paint();
    mPaint.setDither(true);
    mPaint.setColor(Color.BLACK);
    mPaint.setStyle(Paint.Style.STROKE);
    mPaint.setStrokeJoin(Paint.Join.MITER);
    mPaint.setStrokeCap(Paint.Cap.BUTT);
    mPaint.setStrokeWidth(5);

    //set framelayout for the head layout
    fl = new FrameLayout(this); 
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.TYPE_APPLICATION,
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
            PixelFormat.TRANSLUCENT);
    fl.addView(dp,LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT); 
     this.getWindowManager().addView(fl , lp);

     //cancel button
    Button cancel = new Button(this);
    FrameLayout.LayoutParams params = new FrameLayout.LayoutParams( LayoutParams.MATCH_PARENT, 75 );
    params.bottomMargin =LayoutParams.MATCH_PARENT ;
    params.gravity =Gravity.BOTTOM;
    params.leftMargin =LayoutParams.MATCH_PARENT;
    params.gravity =Gravity.BOTTOM;
    cancel.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
    fl.addView(cancel, params);
    cancel.setOnClickListener(new ButtonClickHandlerCancel());

    //save button
    Button save = new Button(this);
    FrameLayout.LayoutParams params2 = new FrameLayout.LayoutParams( LayoutParams.MATCH_PARENT, 75 );
    params2.topMargin = LayoutParams.MATCH_PARENT;
    params2.gravity =Gravity.BOTTOM;
    params2.rightMargin = LayoutParams.MATCH_PARENT;
    params2.bottomMargin = 75;
    params2.gravity =Gravity.BOTTOM;
    save.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
    fl.addView(save, params2);
    save.setOnClickListener(new ButtonClickHandlerSave());

    //aesthetics for cancel button
    StateListDrawable states = new StateListDrawable();
    states.addState(new int[] {android.R.attr.state_pressed},
        getResources().getDrawable(R.drawable.cpressed));
    states.addState(new int[] {android.R.attr.state_focused},
        getResources().getDrawable(R.drawable.cunpressed));
    states.addState(new int[] { },
        getResources().getDrawable(R.drawable.cpressed));
    cancel.setBackgroundDrawable(states);

    //aesthetics for save button
    StateListDrawable states2 = new StateListDrawable();
    states2.addState(new int[] {android.R.attr.state_pressed},
        getResources().getDrawable(R.drawable.spressed));
    states2.addState(new int[] {android.R.attr.state_focused},
        getResources().getDrawable(R.drawable.sunpressed));
    states2.addState(new int[] { },
        getResources().getDrawable(R.drawable.spressed));
    save.setBackgroundDrawable(states2);
}

Попробуйте заменить: 

public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.layout.menu, menu);
    return true;
}

С этим: 

public boolean onCreateOptionsMenu(Menu menu){
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.layout.menu, menu);
    return(super.onCreateOptionsMenu(menu));
}

Также убедитесь, что ваш макет menu.xml находится в нужном месте и в нем нет ошибок. Видите ли вы какие-либо ошибки в LogCat при запуске приложения?
