高德地图 画点 画面 控制区域

最近进行的项目需要嵌入高德地图，并且需要在地图上画点、画面，点是好画但是面呢，有的大有的小，我需要设置面的可视范围，否则有些面在视野之内有些面在视野之外，所以，在这点上费了点力气。现在将比较完整的代码整理如下：

首先按照相关配置配置成功

 if (aMap == null) {            aMap = mapview.getMap();//            //绘制厂区图            setComMap(comPointBean);//            //初始化地图点标记            initMapData(comPointBean);        }

   /**     * date: 2017/7/28 17:41     * autour: HelenChen     * description: 绘制厂区图     */    private void setComMap(ComPointBean comPointBean) {        if (!StrUtils.isEmpty(comPointBean.getTargetInfo().getCoordinateSet())) {            String coordinateSet = comPointBean.getTargetInfo().getCoordinateSet();            try {                //经纬度 longitude latitude                List<String> longitude = new ArrayList<String>();                List<String> latitude = new ArrayList<String>();                JSONArray array = new JSONArray(coordinateSet);                JSONArray array1 = new JSONArray(array.getString(0));                JSONArray array2 = new JSONArray(array1.getString(0));                JSONArray array3 = new JSONArray(array2.toString());                for (int i = 0; i < array3.length(); i++) {                    JSONArray array4 = new JSONArray(array3.getString(i));                    longitude.add(array4.getString(0));                    latitude.add(array4.getString(1));                }                // 声明 多边形参数对象                PolygonOptions polygonOptions = new PolygonOptions();                LatLng latLng = new LatLng(Double.parseDouble(latitude.get(0)), Double.parseDouble(longitude.get(0)));//给默认值 纬度、经度                LatLngBounds bounds = new LatLngBounds(latLng, latLng);                for (int j = 0; j < longitude.size(); j++) {                    // 定义多边形的每个点点坐标                    latLng = new LatLng(Double.parseDouble(latitude.get(j)), Double.parseDouble(longitude.get(j)));//纬度、经度                    // 添加 多边形的每个顶点（顺序添加）                    polygonOptions.add(latLng);                    //添加边界                    bounds = bounds.including(latLng);                }                mapview.getMap().addPolygon(polygonOptions.fillColor(Color.argb(50, 1, 1, 1)).strokeColor(Color.argb(50, 1, 1, 1)).strokeWidth(1));                //添加边界                float dimenBottom = getResources().getDimension(R.dimen.dimen140);                float dimenLeft = getResources().getDimension(R.dimen.dimen20);                int paddingBottom = Math.round(dimenBottom);                int paddingLeft = Math.round(dimenLeft);//                int paddingLeft,paddingRight,paddingTop,paddingBottom                mapview.getMap().animateCamera(CameraUpdateFactory.newLatLngBoundsRect(bounds, paddingLeft, paddingLeft, paddingLeft, paddingBottom));            } catch (JSONException e) {                e.printStackTrace();            }        }    }

注意：
当点和面同时存在时，需要将点的属性设置为false，然后设置面的边界时候才会起作用，设置边界api如下：
