多角形を作るためにGoogleマップにマーカーを追加したい

Question

これはコード

私はマップに地図を追加するために複数回試してみてください。

public class MainActivity extends Activity 
    implements OnMapClickListener, OnMapLongClickListener, OnMarkerClickListener, OnMapReadyCallback { 

final int RQS_GooglePlayServices = 1; 
private GoogleMap myMap; 

Location myLocation; 
TextView tvLocInfo; 

boolean markerClicked; 
PolygonOptions polygonOptions; 
Polygon polygon; 



@Override 
protected void onCreate(Bundle savedInstanceState) { 
    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 
     // ActivityCompat#requestPermissions 
     // here to request the missing permissions, and then overriding 
     // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
     //           int[] grantResults) 
     // to handle the case where the user grants the permission. See the documentation 
     // for ActivityCompat#requestPermissions for more details. 
     myMap.setMyLocationEnabled(true); 

     myMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); 



     return; 


    } 

    myMap.setOnMapClickListener(this); 
    myMap.setOnMapLongClickListener(this); 
    myMap.setOnMarkerClickListener(this); 


    markerClicked = false; 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
     case R.id.menu_legalnotices: 
      String LicenseInfo = GooglePlayServicesUtil.getOpenSourceSoftwareLicenseInfo(
        getApplicationContext()); 
      AlertDialog.Builder LicenseDialog = new AlertDialog.Builder(MainActivity.this); 
      LicenseDialog.setTitle("Legal Notices"); 
      LicenseDialog.setMessage(LicenseInfo); 
      LicenseDialog.show(); 
      return true; 
    } 
    return super.onOptionsItemSelected(item); 
} 

@Override 
protected void onResume() { 

    super.onResume(); 

    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()); 

    if (resultCode == ConnectionResult.SUCCESS) { 
     Toast.makeText(getApplicationContext(), 
       "isGooglePlayServicesAvailable SUCCESS", 
       Toast.LENGTH_LONG).show(); 
    } else { 
     GooglePlayServicesUtil.getErrorDialog(resultCode, this, RQS_GooglePlayServices); 
    } 

} 

@Override 
public void onMapClick(LatLng point) { 
    tvLocInfo.setText(point.toString()); 
    myMap.animateCamera(CameraUpdateFactory.newLatLng(point)); 

    markerClicked = false; 
} 

@Override 
public void onMapLongClick(LatLng point) { 
    tvLocInfo.setText("New marker added@" + point.toString()); 
    myMap.addMarker(new MarkerOptions().position(point).title(point.toString())); 

    markerClicked = false; 
} 

@Override 
public boolean onMarkerClick(Marker marker) { 

    if (markerClicked) { 

     if (polygon != null) { 
      polygon.remove(); 
      polygon = null; 
     } 

     polygonOptions.add(marker.getPosition()); 
     polygonOptions.strokeColor(Color.RED); 
     polygonOptions.fillColor(Color.BLUE); 
     polygon = myMap.addPolygon(polygonOptions); 
    } else { 
     if (polygon != null) { 
      polygon.remove(); 
      polygon = null; 
     } 

     polygonOptions = new PolygonOptions().add(marker.getPosition()); 
     markerClicked = true; 
    } 

    return true; 
} 

@Override 
public void onMapReady(GoogleMap googleMap) { 

    myMap = googleMap; 

    // Add a marker in Sydney and move the camera 
    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 
     // ActivityCompat#requestPermissions 
     // here to request the missing permissions, and then overriding

     myMap.setMyLocationEnabled(true); 
     return; 
    } 



} 

}

ここではmapをid

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