地图上的多个多边形

Question

我设法在地图上绘制了一个多边形。我使用的代码：

private void drawPolygons() {

    PolygonOptions polygonOptions = new PolygonOptions();
    polygonOptions.addAll(arrayPolygon);
    polygonOptions.strokeColor(Color.CYAN);
    polygonOptions.strokeWidth(4);
    polygonOptions.fillColor(Color.CYAN);
    Polygon polygon = googleMap.addPolygon(polygonOptions);

}

我正在尝试画另一个。我这样尝试过：

private void drawPolygons() {

    PolygonOptions polygonOptions = new PolygonOptions();
    polygonOptions.addAll(arrayPolygon);
    polygonOptions.addAll(arrayPolygonSecond);
    polygonOptions.strokeColor(Color.CYAN);
    polygonOptions.strokeWidth(4);
    polygonOptions.fillColor(Color.CYAN);
    Polygon polygon = googleMap.addPolygon(polygonOptions);

}

这两个LatLng阵列刚刚搞砸（两个阵列的顶点都已连接）。我需要将这两个多边形分开。

任何帮助将不胜感激。谢谢你。

Answer 1

找到了解决方案。我必须做两个分开的功能。这是代码：

private void drawPolygons() {

    PolygonOptions polygonOptions = new PolygonOptions();
    polygonOptions.addAll(arrayPolygonOne);
    polygonOptions.strokeColor(Color.CYAN);
    polygonOptions.strokeWidth(4);
    polygonOptions.fillColor(Color.CYAN);
    Polygon polygon = googleMap.addPolygon(polygonOptions);

}

private void drawPolygonsOne() {

    PolygonOptions polygonOptions = new PolygonOptions();
    polygonOptions.addAll(arrayPolygonOne);
    polygonOptions.strokeColor(Color.CYAN);
    polygonOptions.strokeWidth(4);
    polygonOptions.fillColor(Color.CYAN);
    Polygon polygon = googleMap.addPolygon(polygonOptions);

}

Answer 2

此代码，dinamyc绘制了多个多边形区域，

List<LatLng> allArea;  
  for(HeadArea area : data.getListHeadAreas()){
      allArea = new ArrayList<>();
      for(DetailArea detailArea : area.getDetailAreas()){
         allArea.add(new LatLng(detailArea.getLatitude(), detailArea.getLongitude()));
      }
      mMap.addPolygon(new PolygonOptions()
                    .addAll(PolyUtil.simplify(allArea, 3))
                    .fillColor(Color.RED)
                    .strokeColor(Color.BLUE)
                    .strokeWidth(3));
  }
