我有一个 android 应用程序，其中的地图填充了具有销售属性的模型。

我能够实现自定义ClusterRenderer以在集群图标上显示总销售额而不是集群大小。

我遇到的问题是例如。

ClusterA 有 5 个ClusterItems，总销售额为 100 万

ClusterB 有 15 个ClusterItems，总销售额为 100k

由于集群的默认行为，集群 B 比集群 A 大（因为它有更多ClusterItems）

有没有办法让我劫持渲染器，以便集群标记的大小与我的总销售额而不是集群大小一起缩放？

任何帮助将不胜感激！

添加我的 clusterrenderer 代码

public class MyClusterRenderer extends DefaultClusterRenderer<Store> {

private final NavigableMap<Long, String> suffixes = new TreeMap<>();
private IconGenerator mClusterIconGenerator;
private Context context;

//for cluster icon
private ShapeDrawable mColoredCircleBackground;

public MyClusterRenderer(Context context, GoogleMap map, ClusterManager<Store> clusterManager) {
    super(context, map, clusterManager);
    this.context = context;

    //for label prefix processing
    suffixes.put(1_000L, "k");
    suffixes.put(1_000_000L, "M");
    suffixes.put(1_000_000_000L, "G");
    suffixes.put(1_000_000_000_000L, "T");
    suffixes.put(1_000_000_000_000_000L, "P");
    suffixes.put(1_000_000_000_000_000_000L, "E");

    mClusterIconGenerator = new IconGenerator(context);
    //pre processing for cluster icons
    mClusterIconGenerator.setContentView(makeSquareTextView(context));
    mClusterIconGenerator.setTextAppearance(R.style.amu_ClusterIcon_TextAppearance);
    mClusterIconGenerator.setBackground(makeClusterBackground());
}

private SquareTextView makeSquareTextView(Context context) {

    SquareTextView squareTextView = new SquareTextView(context);
    ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    squareTextView.setLayoutParams(layoutParams);
    squareTextView.setId(R.id.amu_text);
    int twelveDpi = 12 * getDensity();
    squareTextView.setPadding(twelveDpi, twelveDpi, twelveDpi, twelveDpi);
    return squareTextView;
}

@Override
protected void onBeforeClusterItemRendered(Store item, MarkerOptions markerOptions) {
    //individual markers here
    markerOptions.icon(getIcon(item));
    super.onBeforeClusterItemRendered(item, markerOptions);
}

@Override
protected void onBeforeClusterRendered(Cluster<Store> cluster, MarkerOptions markerOptions) {
    Bitmap icon = mClusterIconGenerator.makeIcon(getTotalSalesWithFormat((List<Store>) cluster.getItems()));
    BitmapDescriptor descriptor = BitmapDescriptorFactory.fromBitmap(icon);
    markerOptions.icon(descriptor);
}

private int getDensity(){
    return (int) context.getResources().getDisplayMetrics().density;
}

private LayerDrawable makeClusterBackground() {
    mColoredCircleBackground = new ShapeDrawable(new OvalShape());
    mColoredCircleBackground.setColorFilter(context.getResources().getColor(R.color.My_green), PorterDuff.Mode.SRC_ATOP);
    ShapeDrawable outline = new ShapeDrawable(new OvalShape());
    outline.getPaint().setColor(context.getResources().getColor(android.R.color.transparent)); // Transparent white.
    LayerDrawable background = new LayerDrawable(new Drawable[]{outline, mColoredCircleBackground});
    int strokeWidth = getDensity() * 3;
    background.setLayerInset(1, strokeWidth, strokeWidth, strokeWidth, strokeWidth);
    return background;
}

private String getTotalSalesWithFormat(List<Store> list){
    return format(getTotalSales(list));
}

private int getTotalSales(List<Store> list){
    int sum = 0;
    for(Store s : list){
        sum += s.getSales();
    }
    return sum;
}

private BitmapDescriptor getIcon(Store item){
    Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), R.drawable.circle);
    Bitmap mutable = bmp.copy(Bitmap.Config.ARGB_8888, true);
    Canvas canvas = new Canvas(mutable);

    Paint p = new Paint();
    p.setColor(Color.WHITE);

    canvas.drawText(String.valueOf(item.getSales()), 0, 50, p);

    return BitmapDescriptorFactory.fromBitmap(mutable);
}

private String format(long value) {
    //Long.MIN_VALUE == -Long.MIN_VALUE so we need an adjustment here
    if (value == Long.MIN_VALUE) return format(Long.MIN_VALUE + 1);
    if (value < 0) return "-" + format(-value);
    if (value < 1000) return Long.toString(value); //deal with easy case

    Map.Entry<Long, String> e = suffixes.floorEntry(value);
    Long divideBy = e.getKey();
    String suffix = e.getValue();

    long truncated = value / (divideBy / 10); //the number part of the output times 10
    boolean hasDecimal = truncated < 100 && (truncated / 10d) != (truncated / 10);
    return hasDecimal ? (truncated / 10d) + suffix : (truncated / 10) + suffix;
}

}
