这是代码

我已尝试多次添加标记到地图请指导。

public class MainActivity extends Activity

Polygon polygon;



@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    tvLocInfo = (TextView) findViewById(R.id.locinfo);

    FragmentManager myFragmentManager = getFragmentManager();
    MapFragment myMapFragment
            = (MapFragment) myFragmentManager.findFragmentById(R.id.map);
    myMapFragment.getMapAsync(this);

    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        // TODO: Consider calling

我从GoogleMapV2获取此代码，但我无法在谷歌地图上制作标记

如何将标记添加到谷歌地图

请帮助

Answer 1

我将map称为id

var myMarker = new google.maps.Marker({
             position: latlng,
             map: map,
             title:"fggfh.Pvt.Ltd"
             });

我想在谷歌地图上添加标记来制作多边形
