Comment sélectionner une tuile particulière lorsque cliqué et gonfler un bitmap sur elle dans tileview android

je montre une grande image en utilisant Tileview en utilisant TileView bibliothèque

maintenant je veux montrer un cercle dans une limite rect quand cliked sur des tuiles particulières.

Comment obtenir sur quelle tuile cliqué? et comment l'afficher BitMmap au-dessus de la tuile?

public class LargeImageTileViewActivity extends TileViewActivity {
    TileView tileView;
    @Override
    public void onCreate( Bundle savedInstanceState ) {

        super.onCreate( savedInstanceState );

        // multiple references
        tileView = getTileView();

        // by disabling transitions, we won't see a flicker of background color when moving between tile sets
        tileView.setTransitionsEnabled( false );

        // size of original image at 100% scale
        tileView.setSize( 2835, 4289 );

        // detail levels
        tileView.addDetailLevel( 1.000f, "tiles/painting/1000/%col%_%row%.jpg");
        tileView.addDetailLevel( 0.500f, "tiles/painting/500/%col%_%row%.jpg");
        tileView.addDetailLevel( 0.250f, "tiles/painting/250/%col%_%row%.jpg");
        tileView.addDetailLevel( 0.125f, "tiles/painting/125/%col%_%row%.jpg");

        // set scale to 0, but keep scaleToFit true, so it'll be as small as possible but still match the container
        tileView.setScale( 0 );

        // let's use 0-1 positioning...
        tileView.defineRelativeBounds( 0, 0, 1,  1 );

        // frame to center
        frameTo( 0.5, 0.5 );
        tileView.addTileViewEventListener( listener );
    }
    private TileViewEventListenerImplementation listener = new TileViewEventListenerImplementation(){
        public void onTap( int x, int y ) {
            SampleCallout callout = new SampleCallout(LargeImageTileViewActivity.this);


            tileView.slideToAndCenter(x, y);
            //Toast.makeText(mContext, "Center " + tempStore.getCenterX() + " " + tempStore.getCenterY(), Toast.LENGTH_SHORT).show();
            tileView.addCallout(callout, x, y, -0.5f, -1.0f);

            callout.transitionIn();
        }
    };
}
