Question

我尝试在我的应用程序映射中聚集一些点，它第一次完成工作并且数据聚集但是当尝试使用新数据再次更新列表时不发生更改并且群集仍然存在我尝试使用clearItems() ，clear()地图，但没有变化，以下是我的代码，任何人都可以帮忙。

地图代码

((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(final GoogleMap googleMap) {
        mMap = googleMap;
        LatLngBounds ADELAIDE = new LatLngBounds(
                new LatLng(16.57946, 35.69014), new LatLng(31.67252, 50.20833));
        mMap.setLatLngBoundsForCameraTarget(ADELAIDE);
        final LatLng location = new LatLng(mDefaultLat, mDefaultLng);
        mClusterManager = new ClusterManager<>(getContext(), mMap);
        mClusterManager.setRenderer(new ClusterRenderer(getContext(), mMap, mClusterManager));
        final CameraPosition[] mPreviousCameraPosition = {null};
        mMap.setOnCameraIdleListener(new GoogleMap.OnCameraIdleListener() {
            @Override
            public void onCameraIdle() {
                CameraPosition position = googleMap.getCameraPosition();
                mDefaultLat = position.target.latitude;
                mDefaultLng = position.target.longitude;
                locationFromMap = true;
                populate();
                if (mPreviousCameraPosition[0] == null || mPreviousCameraPosition[0].zoom != position.zoom) {
                    mPreviousCameraPosition[0] = googleMap.getCameraPosition();
                    addItems();
                }
            }
        });
        mMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
            @Override
            public void onMapLoaded() {
                mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(location, 16));

            }
        });

        mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
            @Override
            public boolean onMarkerClick(Marker marker) {
                try {
                    new OfficeDialog(mActivity, officeList.get(Integer.parseInt(marker.getSnippet()))).show();
                } catch (Exception e) {

                }
                return true;
            }
        });

    }
});

addItems功能

private void addItems() {
    if (!listAdded && officeList.size() > 0) {
        mClusterManager.clearItems();
        mClusterManager.cluster();
        mClusterManager.addItems(officeList);
        listAdded = true;
    }
    mClusterManager.cluster();
}

和我的集群管理器自定义渲染

public class ClusterRenderer extends DefaultClusterRenderer<Office> {
    Context context;
    private IconGenerator iconGenerator;
    private float density;



    public ClusterRenderer(Context context, GoogleMap map, ClusterManager<Office> clusterManager) {
        super(context, map, clusterManager);
        clusterManager.setRenderer(this);
        this.context = context;
        density = context.getResources().getDisplayMetrics().density;
    }

    @Override
    protected void onBeforeClusterItemRendered(Office item, MarkerOptions markerOptions) {
        markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.ejar_location_icon_copy));
    }

    @Override
    protected void onBeforeClusterRendered(Cluster<Office> cluster, MarkerOptions markerOptions) {
        if(iconGenerator == null) {
            iconGenerator = new IconGenerator(context);
            iconGenerator.setContentView(makeTextView(context));
        }
        iconGenerator.setBackground(makeBackground(false, cluster.getSize()));

        markerOptions.icon(BitmapDescriptorFactory.fromBitmap(iconGenerator.makeIcon(String.valueOf(cluster.getSize()))));
    }

    @Override
    protected void onClusterRendered(Cluster<Office> cluster, Marker marker) {
        super.onClusterRendered(cluster, marker);
    }

    @Override
    protected boolean shouldRenderAsCluster(Cluster<Office> cluster) {
        return cluster.getSize() > 1;
    }

    private ShapeDrawable makeBackground(boolean isClicked, int size) {
        ShapeDrawable background = new ShapeDrawable(new OvalShape());
        int color = ContextCompat.getColor(context, R.color.colorPrimary);
        if (size < 50) {
            color = ContextCompat.getColor(context, R.color.colorPrimary);
        } else if (size < 100) {
            color = ContextCompat.getColor(context, R.color.cluster_50);
        } else if (size < 200) {
            color = ContextCompat.getColor(context, R.color.cluster_100);
        } else if (size < 1000) {
            color = ContextCompat.getColor(context, R.color.cluster_200);
        } else color = ContextCompat.getColor(context, R.color.cluster_1000);

        background.setColorFilter(color, PorterDuff.Mode.SRC_ATOP);
        return background;
    }

    private SquareTextView makeTextView(Context context) {
        SquareTextView squareTextView = new SquareTextView(context);

        ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(-2, -2);
        squareTextView.setLayoutParams(layoutParams);
        squareTextView.setTextColor(ContextCompat.getColor(context, R.color.white));
        squareTextView.setId(com.google.maps.android.R.id.text);
        int twelveDpi = (int) (12.0F * density);
        squareTextView.setPadding(twelveDpi, twelveDpi, twelveDpi, twelveDpi);
        return squareTextView;
    }

    public IconGenerator getIconGenerator(boolean isClicked) {
        iconGenerator.setBackground(makeBackground(isClicked, 0));
        return iconGenerator;
    }
}

在调试和搜索此问题后，我没有找到任何理由，所以在检查我的网络服务后，我发现了问题。
Web服务返回我的对象的静态位置，因此在修复它之后集群没有更改，应用程序正常工作而没有任何问题。

CLuster Manager未在地图中更新
