这是我的代码，

ivmainmenu.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            if (p != null)
                   showPopup(Home.this, p);
                 }

        private void showPopup(Home context, Point p) {
            // TODO Auto-generated method stub
            int popupWidth = 200;
               int popupHeight = 150;

               // Inflate the popup_layout.xml
               LinearLayout viewGroup = (LinearLayout) context.findViewById(R.id.popup_element);
               LayoutInflater layoutInflater = (LayoutInflater) context
                 .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
               View layout = layoutInflater.inflate(R.layout.popupwindow, viewGroup);

               final PopupWindow popup = new PopupWindow(context);
               popup.setContentView(layout);
               popup.setWidth(popupWidth);
               popup.setHeight(popupHeight);
               popup.setFocusable(true);

               int OFFSET_X = 30;
               int OFFSET_Y = 30;

               popup.setBackgroundDrawable(new BitmapDrawable());

               popup.showAtLocation(layout, Gravity.NO_GRAVITY, p.x + OFFSET_X, p.y + OFFSET_Y);


        }
               });
