将实际路径格式转换为Android中的Uri

Question

例如

真正的路径是mnt/sdcard/image_1.jpg Uri路径是内容:// media/external/images/media/140喜欢这个

  Uri photoUri =Uri.parse("content://media/external/images/media/140");
                                            Log.d("selectedphoto",""+photoUri);
               selectedImagePath = getPath(photoUri);

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



    return cursor.getString(column_index);
    }

在上面的代码中我将Uri转换为实际路径,但是dnt知道如何将实际路径转换为Uri
