Clicking on Overlays in MapView

Issue

I've created a MapActivity that uses MapView to place drawables on an ArrayList of points I've specified. This works great.

I want the user to be able to press each point and have a bubble appear (as when you are using Google Maps in your web browser) with some information about that point.

I can not figure out how to do this. Could someone point me to some good resources?

Solution

If you are using ItemizedOverlay, just override onTap() in your overlay class. Here is a sample project demonstrating this.

The relevant snippet there is:

    @Override
    protected boolean onTap(int i) {
        Toast.makeText(NooYawk.this, items.get(i).getSnippet(),
                        Toast.LENGTH_SHORT).show();

        return(true);
    }

Instead of displaying a Toast, you can do something else. For example, here is a sample project that displays a popup. And here's an Android library project that displays bubbles that point to the actual marker.
