小部件锁屏

我已经在这里阅读后，也进行搜索，但没有找到答案。
是否可以添加小部件屏幕锁定？我需要它的音乐播放器的控制。
是否有某种方式或唯一方法是创建自己的锁屏与锁定，解锁的实施？
我想自定义活动，但它显示在锁定画面和解锁是不可见的，直到我preSS背部和活动被关闭。

I have read post here and also search for it, but haven't found answer. Is it possible add widget to lockscreen? I need it for music player control. Is there some way or only way is to create own lockscreen with lock, unlock implementation? I tried custom activity but it's displayed over the lockscreen and unlock is not visible until i press back and activity is closed.

谢谢，
