Android MapView, finding center of map, determining end of animation from fling gesture

The closest thing I could find related to this was the following:

android maps: how to determine map center after a drag has been completed

I want to determine the final "resting place" of the center of the map after the user has "flung" it. I am intercepting the touch event, when the user is lifting their finger up, but this doesn't work when the map is flung with a swipe motion, as the map continues to move at that point. Is there a c开发者_开发百科allback that can be implemented when the map animation is complete? I looked at the documentation for the MapView, Overlay, MapController etc classes and I haven't seen anything that seems to help.


I also have been looking for a "did end drag" solution that detects the map center at the moment exactly after the map ended moving. I haven't found it, so I've made this simple implementation that did work fine:

private class MyMapView extends MapView {

    private GeoPoint lastMapCenter;
    private boolean isTouchEnded;
    private boolean isFirstComputeScroll;

    public MyMapView(Context context, String apiKey) {
        super(context, apiKey);
        this.lastMapCenter = new GeoPoint(0, 0);
        this.isTouchEnded = false;
        this.isFirstComputeScroll = true;
    }
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN)
            this.isTouchEnded = false;
        else if (event.getAction() == MotionEvent.ACTION_UP)
            this.isTouchEnded = true;
        else if (event.getAction() == MotionEvent.ACTION_MOVE)
            this.isFirstComputeScroll = true;
        return super.onTouchEvent(event);
    }
    @Override
    public void computeScroll() {
        super.computeScroll();
        if (this.isTouchEnded &&
            this.lastMapCenter.equals(this.getMapCenter()) &&
            this.isFirstComputeScroll) {
            // here you use this.getMapCenter() (e.g. call onEndDrag method)
            this.isFirstComputeScroll = false;
        }
        else
            this.lastMapCenter = this.getMapCenter();
    }
}

That's it, I hope it helps! o/
