public class LargeImageTileViewActivity extends TileViewActivity {

        super.onCreate( savedInstanceState );

        // multiple references

        // 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( 0.125f, "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 );

            SampleCallout callout = new SampleCallout(LargeImageTileViewActivity.this);


            tileView.slideToAndCenter(x, y);
            //Toast.makeText(mContext, "Center " + tempStore.getCenterX() + " " + tempStore.getCenterY(), Toast.LENGTH_SHORT).show();
