我在Android的应用程序，并使用云存储器像Dropbox的一些文件共享。要开始分享我把 android.intent.action.SEND 。 在所显示的列表中我看到了谷歌驱动器应用程序（previously安装），所以我尝试将文件发送到它 - 它的工作原理确定，该文件显示在驱动器列表

然后，另一台设备上我想读这个文件。我扔了 android.intent.action.GET_CONTENT 的意图，选择驱动器，然后不知道怎么去申请。我收到一个开放的我们是这样的：

content://com.google.android.apps.docs.files/exposed_content/6jn9cnzdJbDywpza%2BlW3aA%3D%3D%0A%3BRV%2FaV94o%2FCcW4HGBYArtwOdHqt%2BrsYO4WmHcs6QWSVwp%2FXogkRAgit7prTnfp00a%0A

我不知道如何转化为物理文件路径。我怎么能从此得到的文件内容是什么？

我打得周围的内容提供商，并能获取文件名，而不是完整的路径或其他任何东西。

有关保管箱我得到的文件：// 风格的URI，直接，简单，效果很好。

解决方案

这是送你的URI内容提供商，你可以使用它与ContentResolver的，例如如：

  getContentResolver（）查询（URI contentUri，字符串[]投影，选择字符串，字符串[] selectionArgs两个，字符串排序顺序）。
 

编辑：为了得到真实路径名使用提供以下

Android:获取文件的Uri从内容乌里？

I have an app on android that does some file sharing using cloud storages like dropbox. To start sharing I throw android.intent.action.SEND. On the list that is shown I see the Google Drive app (previously installed), so I try sending the file to it - it works ok, the file appears in the Drive list.

Then, on another device I want to read this file. I throw the android.intent.action.GET_CONTENT intent, choose Drive and then don't know how to get to file. I receive an Uri something like this:

content://com.google.android.apps.docs.files/exposed_content/6jn9cnzdJbDywpza%2BlW3aA%3D%3D%0A%3BRV%2FaV94o%2FCcW4HGBYArtwOdHqt%2BrsYO4WmHcs6QWSVwp%2FXogkRAgit7prTnfp00a%0A

which I don't know how to transform to physical file path. How could I get the file contents from this?

I played around the content provider and can get the file name, but not the full path or anything else.

For the dropbox I get the file:// style uri, straight and simple, works well.

解决方案

It is sending you uri of content provider which you can use it with ContentResolver,for example such as:

getContentResolver().query(Uri contentUri, String[] projection, String selection, String[] selectionArgs, String sortOrder);

Edit: For getting real path names use the solution provided below
