获取真实路径的URI，Android的奇巧新的存储访问架构 [英] Get real path from URI, Android KitKat new storage access framework

问题描述

在在奇巧的新画廊访问我得到了我的SD卡中的真实路径用这种方法

Before new gallery access in KitKat I got my real path in sdcard with this method

public String getPath(Uri uri) {
   String[] projection = { MediaStore.Images.Media.DATA };
   Cursor cursor = managedQuery(uri, projection, null, null, null);
   startManagingCursor(cursor);
   int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
   cursor.moveToFirst();
 return cursor.getString(column_index);
}

现在，该Intent.ACTION_GET_CONTENT返回不同的数据：

Now, the Intent.ACTION_GET_CONTENT return different data:

在

content://media/external/images/media/62

现在：

content://com.android.providers.media.documents/document/image:62

我怎么能管理，以获得SD卡的实际路径？

How could I manage to obtain the real path in sdcard?

推荐答案

注意：这个答案的地址问题的一部分。对于一个完整的解决方案（在库的形式），看看用户保罗·伯克回答以下。

Note: This answer addresses part of the problem. For a complete solution (in the form of a library), look at user Paul Burke's answer below.

您可以使用URI来获得文件ID ，然后查询或者 MediaStore.Images.Media.EXTERNAL_CONTENT_URI 或 MediaStore.Images.Media.INTERNAL_CONTENT_URI （视SD卡的情况）。

You could use the Uri to obtain document id, and then query either MediaStore.Images.Media.EXTERNAL_CONTENT_URI or MediaStore.Images.Media.INTERNAL_CONTENT_URI (depending on the SD card situation).

要获取文档ID：

// Will return "image:x*"
String wholeID = DocumentsContract.getDocumentId(uriThatYouCurrentlyHave);

// Split at colon, use second item in the array
String id = wholeID.split(":")[1];

String[] column = { MediaStore.Images.Media.DATA };     

// where id is equal to             
String sel = MediaStore.Images.Media._ID + "=?";

Cursor cursor = getContentResolver().
                          query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
                          column, sel, new String[]{ id }, null);

String filePath = "";

int columnIndex = cursor.getColumnIndex(column[0]);

if (cursor.moveToFirst()) {
    filePath = cursor.getString(columnIndex);
}   

cursor.close();

参考：我没能找到这个解决方案是从岗位。我想问问楼主在这里作出贡献。会看一些在今晚。
