How do I respond to a tap on an Android MapView, but ignore pinch-zoom?

Question

I have a MapView in an activity and it works fine, the map shows, and it responds to taps, and I can extract the location easily. However this handler is also responding to

After much head-scratching and trying various approaches, this one is working well so far. The code follows the motion events. When we get an ACTION_DOWN event, it marks the isPinch flag as false (we don't know if it's a pinch or not yet), but as soon as we get a touch event (i.e. ACTION_MOVE) involving two fingers, isPinch is set to true, and so when the onTap() event fires, it can see if there was a pinch or not.

class MapOverlay extends com.google.android.maps.Overlay
{
private boolean   isPinch  =  false;

@Override
public boolean onTap(GeoPoint p, MapView map){
    if ( isPinch ){
        return false;
    }else{
        Log.i(TAG,"TAP!");
        if ( p!=null ){
            handleGeoPoint(p);
            return true;            // We handled the tap
        }else{
            return false;           // Null GeoPoint
        }
    }
}

@Override
public boolean onTouchEvent(MotionEvent e, MapView mapView)
{
    int fingers = e.getPointerCount();
    if( e.getAction()==MotionEvent.ACTION_DOWN ){
        isPinch=false;  // Touch DOWN, don't know if it's a pinch yet
    }
    if( e.getAction()==MotionEvent.ACTION_MOVE && fingers==2 ){
        isPinch=true;   // Two fingers, def a pinch
    }
    return super.onTouchEvent(e,mapView);
}

}
