Position, Shadow and dismissing of PopupWindow like an Actionbar Menu [Android]

I am trying to create a PopupWindow that works like an Actionbar Menu like in Chrome for android - example: How to create custom sub menu like Google Chrome application

Here's what I have so far:

Currently - I have 3 problems:

1. I need to position the menu to the right Actionbar button, and below it. like the usual Menus..

2. I need to have a shadow on the PopupWindow (for some reason it is removed, as I know PopupWindow automatically have this shadow around it)

3. When clicking outside the PopupWindow, I need it to dismiss like the usual menus of the Actionbar..

Here's my code- On click of the Actionbar button this is the code that runs:

LayoutInflater inflater = (LayoutInflater) MainActivity.this
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final PopupWindow pw = new PopupWindow(inflater.inflate(
            R.layout.options_menu, null, false), LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, true);
    pw.showAtLocation(findViewById(R.id.main_cont), Gravity.NO_GRAVITY, 50, this.getSupportActionBar().getHeight() + 1);


    ListView moreOptions = (ListView)pw.getContentView().findViewById(R.id.moreOptions);
    String[] options = new String[] { "Settings", "Feedback", "Contribute", "DashClock Integration", "Tutorial", "ViewPager Demo", "Expandable List Demo", "Change Language", "Add 5 to list", "Add 20 to list" };

    final ArrayList<String> moreOptionsList = new ArrayList<String>();
    for (int i = 0; i < options.length; ++i) {
        moreOptionsList.add(options[i]);
    }

    ArrayAdapter<String> moreOptionsAdapter=new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1,
            moreOptionsList);
    moreOptions.setAdapter(moreOptionsAdapter);


    //pw.setBackgroundDrawable(this.getResources().getDrawable(R.drawable.listview_bg_inverted));
    /*
    pw.setTouchable(true);
    pw.setFocusable(false);
    */
    pw.setOutsideTouchable(true);
