我有一个城市各个区域的连续 LatLngs.有什么方法可以用它创建可点击的多边形.曾经的方法是
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
setOnMapClickListener
.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?
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();
}
}
});
希望对您有所帮助.
