Add custom context items in context menu for Android

I need some help with adding the custom items in the copy and paste menu for Android. I want to add "Format" in the copy and paste context menu. I have tried a number of ways to add them such as intent-filter and some others but i am not be able to get them to work. If you can do it for me to add the custom context menu item, that would be great. Will pay after the work is done. Thanks!!!
