自定義的PopupWindow

在Activity中

  mPopwindow = new CameraPopwindow(getActivity(), itemsOnClick);
                mPopwindow.setFocusable(true); // 獲取焦點
                mPopwindow.setOutsideTouchable(true);
                mPopwindow.showAtLocation(view, Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
