显示文件

• We ignored some of the methods in the content label providers , the tree viewer is displaying files as well as folders , there are no icons being displayed , and there is no sign of a menu bar , tool bar , status line , or any pop - up menus
  我们没有考虑内容标签提供程序中的一些方法，树查看器既显示文件又显示文件夹，没有显示图标，而且没有涉及菜单栏、工具栏、状态栏或任何弹出菜单。
