1. Define an interface and call it IChangeListener (or something like that) and define a method inside which will do the work (ex, changeFragment()) (or call another method which will do the work) for changing the fragment).
2. Make your activity implement the interface, or make an anonymous class within the activity implement it.
3. Make a paramerized constructor of your fragment, which accepts a IChangeListener parameter.
4. When initializing the fragment, pass your IChangeListener implementation (the anonymous class or the activity, implementing it)
5. Make the onClick listener of the button call the changing method of the IChangeListener.
