从Uri中获取真是文件路径的方法

这个方法是从网上找到的，感谢网友的无私奉献！

 

 1     public static String getFilePathFromUri(Context context, Uri uri,
 2             String[] projection, String selection, String[] selectionArgs,
 3             String sortOrder) {
 4         Cursor cursor = context.getContentResolver().query(uri, projection,
 5                 selection, selectionArgs, sortOrder);
 6         int index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
 7         cursor.moveToFirst();
 8         String path = cursor.getString(index);
 9         cursor.close();
10         cursor = null;
11         return path;
12     }
