Question

With this code:

private class WRYLocationListener implements LocationListener
//private class WRYLocationListener extends LocationListener <- I tried this, too, with the same results
{
    @Override
    public void onLocationChanged(Location loc) {
. . .

I get this err msg:

The method onLocationChanged(Location) of type Activity.WRYLocationListener must override a superclass method.

I got this code from a book; “extends” makes more sense to me here than “implements” (maybe it’s a typo in the book?), but even with “extends” I get the same err msg…

Answer 1

implements is the only thing that makes sense, because LocationListener is an interface.

The @Override annotation for interfaces, however, is a JDK 6 feature, not JDK 5, and should be removed. In JDK 5, @Override is valid only if a class overrides a superclass method (as opposed to implementing an interface method).
