推荐答案

下面是从这是一个code段教程，这显示了选秀文件意图的实现：

Here's a code snippet from this tutorial, that shows the pick file Intent implementation:

    protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
   if (requestCode == PICK_REQUEST_CODE)
   {
   if (resultCode == RESULT_OK)
   {
      Uri uri = intent.getData();
      String type = intent.getType();
      LogHelper.i(TAG,"Pick completed: "+ uri + " "+type);
      if (uri != null)
      {
         String path = uri.toString();
         if (path.toLowerCase().startsWith("file://"))
         {
            // Selected file/directory path is below
            path = (new File(URI.create(path))).getAbsolutePath();
         }

      }
   }
   else LogHelper.i(TAG,"Back from pick with cancel status");
   }
}

正如你所看到的，你的 onActivityResult（）方法返回的意图，其中包含的文件路径，可以使用 intent.getData（）法来提取。然后你只需创建一个使用该路径的File对象，并使用 file.getAbsolutePath（）方法得到它的绝对路径。希望这有助于。

As you can see, your onActivityResult() method returns you the Intent, which contains the file path, that can be extracted using intent.getData() method. Then you just create a File object using this path, and get the absolute path of it using file.getAbsolutePath() method. Hope this helps.
