Question

还是在绘制第四个点的时候，sceneControl.getScene().getTrackingLayer().remove(index);  这句有问题，还是没有解决。

之前用的Tracking3DEvent，就只能绘制三个点，后续无响应，按照你们的解决办法换成了Tracked3DEvent

但是用Tracked3DEvent的时候，运行在这里就出问题了，断点测试在这断了，不走这里，不知道运行后不显示标注是不是和这个也有关系

   private Tracked3DListener mTracked3dListener = new Tracked3DListener() {
        @Override
        public void tracked(Tracked3DEvent tracked3DEvent) {
            initAnalySis1(sceneControl, tracked3DEvent);
            Log.i("绘制完成", "监听结束");
        }
    };

这是Tracked3DEvent的测面代码

private void measureSurearea(Tracked3DEvent tracked3DEvent) {

        // 加点
        // 更新测量面积
        double TotalArea = tracked3DEvent.getArea();
        double totalcurrentlength = tracked3DEvent.getLength();

        Message msg = new Message();
        Bundle bundle = new Bundle();
        bundle.putDouble("Area", Double.parseDouble(new DecimalFormat("############.##").format(TotalArea)));
        msg.setData(bundle);
        totalLengthHandler.sendMessage(msg);
        Log.v("lzw", "TotalArea=" + TotalArea + ";" + "totalcurrentlength=" + totalcurrentlength);

        //1.12
        TextStyle textStyle = new TextStyle();
        textStyle.setAlignment(TextAlignment.MIDDLECENTER);
        textStyle.setFontScale(1);

        if(TotalArea > 0.0) {
            Point3D innerPoint3D = tracked3DEvent.getGeometry().getInnerPoint3D();
            TextPart3D textPart3D2 = new TextPart3D();
            textPart3D2.setX(innerPoint3D.getX());
            textPart3D2.setY(innerPoint3D.getY());
            textPart3D2.setZ(innerPoint3D.getZ());
            textPart3D2.setText("共" + msg.getData().getDouble("Area") + "平方米");
            Log.i("测试2", "textPart3D=" + textPart3D2.getText());


            GeoText3D geoText3D = new GeoText3D(textPart3D2);
            geoText3D.setTextStyle(textStyle);
            GeoPlacemark geoPlacemark = new GeoPlacemark("3D", geoText3D);

            sceneControl.getScene().getTrackingLayer().add(geoPlacemark, "面积");

        }

    }

想问一下还有什么解决办法
