why Must Override a Superclass Method' Errors after importing a project into Eclipse

Anytime I have to re-import my projects into Eclipse (if I reinstalled Eclipse, or changed the location of the projects), almost all of my overridden methods are not formatted correctly, causing the error The method must override a superclass method.

It may be noteworthy to mention this is with Android projects - for whatever reason, the method argument values are not always populated, so I have to manually populate them myself. For instance:

list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {

    //These arguments have their correct names
    public void onCreateContextMenu(ContextMenu menu, View v,
                                    ContextMenuInfo menuInfo) {                 

will be initially populated like this:

list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {

    //This methods arguments were not automatically provided    
    public void onCreateContextMenu(ContextMenu arg1, View arg2,
                                    ContextMenuInfo arg3) {

The odd thing is, if I remove my code, and have Eclipse automatically recreate the method, it uses the same argument names I already had, so I don't really know where the problem is, other then it auto-formatting the method for me.

This becomes quite a pain having to manually recreate ALL my overridden methods by hand. If anyone can explain why this happens or how to fix it .. I would be very happy.

Maybe it is due to the way I am formatting the methods, which are inside an argument of another method?
