public class MyClusterItemRenderer extends DefaultClusterRenderer<MyClusterItem> {

    private final IconGenerator mIconGenerator;
    private final ShapeDrawable mColoredCircleBackground;
    private final float mDensity;

    private SparseArray<BitmapDescriptor> mIcons = new SparseArray();

    public MyClusterItemRenderer(Context context, GoogleMap map, ClusterManager<MyClusterItem> clusterManager) {
        super(context, map, clusterManager);
        mIconGenerator = new IconGenerator(context);
        mColoredCircleBackground = new ShapeDrawable(new OvalShape());
        mDensity = context.getResources().getDisplayMetrics().density;

        SquareTextView squareTextView = new SquareTextView(context);
        ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(-2, -2);
        squareTextView.setLayoutParams(layoutParams);
        squareTextView.setId(com.google.maps.android.R.id.text);
        int twelveDpi = (int)(12.0F * this.mDensity);
        squareTextView.setPadding(twelveDpi, twelveDpi, twelveDpi, twelveDpi);
        this.mIconGenerator.setContentView(squareTextView);

        mIconGenerator.setTextAppearance(com.google.maps.android.R.style.ClusterIcon_TextAppearance);

        ShapeDrawable outline = new ShapeDrawable(new OvalShape());
        outline.getPaint().setColor(Color.parseColor("#FFFFFF"));
        LayerDrawable background = new LayerDrawable(new Drawable[]{outline, this.mColoredCircleBackground});
        int strokeWidth = (int) (this.mDensity * 3.0F);
        background.setLayerInset(1, strokeWidth, strokeWidth, strokeWidth, strokeWidth);
        mIconGenerator.setBackground(background);

    }



    @Override
    protected void onBeforeClusterRendered(Cluster<MyClusterItem> cluster, MarkerOptions markerOptions) {
        int bucket = this.getBucket(cluster);
        BitmapDescriptor descriptor = (BitmapDescriptor)this.mIcons.get(bucket);
        if(descriptor == null) {
            this.mColoredCircleBackground.getPaint().setColor(this.getColor(bucket));
            descriptor = BitmapDescriptorFactory.fromBitmap(this.mIconGenerator.makeIcon(String.valueOf(cluster.getSize())));
            this.mIcons.put(bucket, descriptor);
        }

        markerOptions.icon(descriptor);
    }
}

活动:

clusterManager.setRenderer(new MyClusterItemRenderer(getApplicationContext(), mGoogleMap, clusterManager));
