You have to find the view of the button and then assign the listener to it like this:

View pview=inflater.inflate(R.layout.menu, (ViewGroup)findViewById(R.layout.dictionarylist));

Button Menu = (Button) pview.findViewById(R.id.Menu);

Menu.setOnClickListener(new Button.OnClickListener() {
            public void onClick(View v) {
                pw.showAtLocation(v, Gravity.CENTER, 0, 0);
                pw.update(0, 0, 200, 250);
                pw.setOutsideTouchable(false);
            }

Also initialize your inflator if you haven't already like this:

Inflator inflator = LayoutInflater.from(this);
