推荐答案

既然你已经储存在您选择到项，你需要从该对象retreive的文件路径，对于工作中添加DELETEFILE对象则（）方法行：

Since you have stored your selection into "item" object then in deleteFile() method you need to retreive the file path from that object, for that to work add the line:

model.absolutePath =  mfile.getAbsolutePath（）;

在getVideoFiles（）方法中的for循环。

in getVideoFiles() method 'for' loop.

还的onCreate状态之前：

also before onCreate state:

ListViewAdapter LV;

然后getVideoFiles在结束状态：

then in getVideoFiles at the end state:

  lv = new ListViewAdapter(this, R.layout.row, videoItems);
  setListAdapter(lv);

终于在DELETEFILE（），你需要状态：

finally in deleteFile() you need to state:

myfile文件=新的文件（item.absolutePath）;

lv.notifyDataSetChanged（）;

lv.notifyDataSetChanged();

和应该努力！
