PopupWindowDialog

使用PopupWindow完成各種dialog

            pop1.showAtLocation(ll_main, Gravity.BOTTOM, 0, 0);
            pop2.showAtLocation(ll_main, Gravity.CENTER, 0, 0);
            pop3.showAsDropDown(btn_pop3);

            控制Gravity可以控制pop的位置  ll_main是本界面的最外層布局

           new PopupWindow(view, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
           new PopupWindow(view, screenWidth * 4 / 5, ViewGroup.LayoutParams.WRAP_CONTENT, true);
           new PopupWindow(popupWindowView, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, true);

           創建pop的時候控制它自己的寬和高
