我有同样的问题，只有发现晦涩的解决方案如何查询通过特定的艺术家所做的所有专辑，然后我想出了这个简单的解决方案：

I had the same problem and only found obscure solutions how to query all albums done by a specific artist, then I came up with this rather simple solution:

Uri.Builder builder = MediaStore.Audio.Artists.EXTERNAL_CONTENT_URI.buildUpon();
builder.appendPath(artistId);
builder.appendPath("albums");

cursor = parent.managedQuery(builder.build(), projection, null,
    null, MediaStore.Audio.Albums.DEFAULT_SORT_ORDER);

编辑： 将上述溶液，以获得开放的可能不是最好的，这也应该工作：

The above solution to get the Uri may be not the nicest, this should also work:

Uri uri = MediaStore.Audio.Artists.Albums.getContentUri("external", artistId);

该artistId是 MediaStore.Audio.Artists._ID 的从previous艺术家查询的价值。

The artistId is the value of the MediaStore.Audio.Artists._ID from a previous Artist query.
