I have continuous LatLngs of various areas in a city. Is there any way I can create clickable polygons with it. Once way to go about would be to

• 使用可用的 LatLngs 生成多边形.(我想用颜色编码在地图上直观地显示多边形)
• 设置setOnMapClickListener.
• 在多边形内做一个点测试.

我知道这很幼稚.有哪些替代方法?

I understand that this is very naive. What are the alternative approaches?

推荐答案

我是这样做的.

    Polygon polygon = getMap().addPolygon(new PolygonOptions()
                    .add(new LatLng(12.780712, 77.770956), new LatLng(12.912006, 77.229738), new LatLng(12.412006, 77.629738), new LatLng(12.912006, 77.229738))
                    .strokeColor(0xFF00AA00)
                    .fillColor(0x2200FFFF)
                    .strokeWidth(2)
    );


    polygon.setClickable(true);

    getMap().setOnPolygonClickListener(new GoogleMap.OnPolygonClickListener() {
        public void onPolygonClick(Polygon polygon) {

            mClusterManager = new ClusterManager<MyItem>(getApplicationContext(), getMap());
            getMap().setOnCameraChangeListener(mClusterManager);
            getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(getMap().getCameraPosition().target, getMap().getCameraPosition().zoom));

            try {
                readItems();
            } catch (JSONException e) {
                Toast.makeText(getApplicationContext(), "Problem reading list of markers.", Toast.LENGTH_LONG).show();
            }

        }
    });
