自定义视图像android的锁定/解锁屏幕

Question

I would like to create effects like lock/unlock screen of android. I have attached the screenshot here as well. In lock screen we have 2 buttons but in my case I am having 3 buttons and the middle button must be draggable.

The middle button can be drag to left/right.

I know I have to create custom view for this to work but I don't have any idea about how to drag button left/right with nice effect(animations) which normally any android phone have.

I need guidance on this, so can anyone suggest me how to approach for this.

Basically i wish to move/slide button left and right and based on that want to take some action.

I have tried making a lockscreen application myself and i almost made it, but here are the facts you will have to face at the end

1. You will not be able to disable home or menu button.
2. you will need user permission (not the one you get while installing the application, the menu pops up every time you press the home button unless the user decides to make your application default home screen, if that does happen you have successfully made a lock screen) if you decide to make a home screen application too.
3. the lock screen doesn't go very well with passwords

But if it helps, here's what i did:

You need to create a service that keeps a check on the screen being off and on.

if the screen is off, you do nothing. when the screen if ON you start the activity and wait for the user to do the thing you want the user to make him unlock the screen. and when he does that you finish() the activity.

While doing that you need to setup a method that can listen to check the incoming calls you can do that by extending PhoneStateListener and also disable the back button.

Good Luck and if you are able to make any further progress do let me know.
