Display Custom Information on Lock Screen In Android [duplicate]

Question

I want to custom LockScreen.

The default Lock screen is like this.

I want to modify this portion of the Lock Screen & Let all other things remain the same. When user locks his phone, it should display custom information on that red box.

So far i have seen one app that does something similar to this things : WidgetLocker

StackOverflow Search so far :

From what I gather, you have to write your lockscreen, then disable the default one. You can listen for screen on and off events then disable the home button by basically making your custom locksceen a launcher.
