android - Having a problen to develop lockscreen for android

Question

I want to develop an android application that will be an alternative lockscreen. I searched a lot and i couldn't found an explanation about how to make an app to work like a lockscreen. I understand that there is no official android API for lockscreens, but there must be way, because there are a lot of alternative lockscreens applications in the market. Does someone know how could i make my app work like a lockscreen? Or if there is a basic code out there of lockscreen app that i can learn from it how to do it? Thanks a lot (:

这通常完成的方式是创建一个成为家庭应用程序的应用程序，然后在屏幕打开时显示您的自定义锁屏并在用户成功解锁时隐藏它以便他们可以使用设备。
