EDIT:

• This answer was best for older google map apis. In google Map V2 this thing is already given.

You can get the code from https://github.com/galex/android-mapviewballoons

you can get selected balloon from the method of "BalloonItemizedOverlay.java" as follow

private void hideOtherBalloons(List<Overlay> overlays) {
        for(int i=0; i<overlays.size();i++ ){
            if (overlays.get(i) instanceof BalloonItemizedOverlay<?> && overlays.get(i) != this) {
                ((BalloonItemizedOverlay<?>) overlays.get(i)).hideBalloon();
            }else{
                BalloonOverlayView.SELECTED_BALLOON = i;
                Log.i(i+" : Baloon Open", BalloonOverlayView.SELECTED_BALLOON+"");
            }
        }
}

To set the data you can use setBalloonData method of BalloonOverlayView.java file as follow:

protected void setBalloonData(Item item, ViewGroup parent) {
        if (item.getTitle() != null) {
            title.setVisibility(VISIBLE);
            title.setText(item.getTitle());
        } else {
            title.setText("");
            title.setVisibility(GONE);
        }
        if (item.getSnippet() != null) {
            snippet.setVisibility(VISIBLE);
            snippet.setText(item.getSnippet());
        } else {
            snippet.setText("");
            snippet.setVisibility(GONE);
        }
}
