本文介绍了一种自定义PopupWindow的方法，包括初始化、布局设置及显示等步骤，并提供了具体的实现代码与XML布局文件。

在Activity中

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

            public class CameraPopwindow extends PopupWindow {

              TextView camera= (TextView) mView.findViewById(R.id.Personal_fragment_camera);

              TextView album= (TextView) mView.findViewById(R.id.Personal_fragment_album);

              TextView personal_dimess= (TextView) mView.findViewById(R.id.Personal_fragment_dimess);
