안드로이드에서 google maps marker를 클릭하십시오?

Question

기본보기가 Google지도 인 활동이 있습니다. 지도를 처음로드 할 때 표식을 설정하지만 클릭하면 표식이나 아무것도 얻을 수 없습니다. 지도는 나타나지만 마커를 클릭하거나 화면을 탭하거나 탭하여 길게 눌러 새 마커를 만들 수 없습니다. 기본적으로 아무것도 할 수 없다 ... 그리고 나는 이유를 알 수 없다! 너희들은 내가 보지 못하는 것을 볼 수 있기를 바란다.

여기가 내 주요 활동입니다.

Answer 1

입니다.

는 if 문 다음 제거

if (mMap == null) 

은 또한 단지 initMap() mapFragment.getMapAsync 후 수익률을 호출합니다. 이 시점에서지도를 사용할 준비가되었음을 알 수 있습니다.

mapFragment.getMapAsync(new OnMapReadyCallback() { 
     @Override 
     public void onMapReady(GoogleMap googleMap) { 
      mMap = googleMap; 
      LatLng sydney = new LatLng(-34, 151); 
      mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
      mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); 
      mMap.animateCamera(CameraUpdateFactory.zoomTo(15), 2000, null); 
      initMap(); 
     } 
    }); 

Answer 2

님의

OnMapReadyCallback

차례로 재정에 구현 해야하는

onMapReady

이제 onMapReady 내에서 Map을 조작 할 수 있습니다. 그 전에지도가 실제로 올바르게 설정되었는지는 확실하지 않습니다.

마커를로드하고 마커 클릭 수신기를 설정하는 것과 같이 맵을 조작하는 모든 것이 onMapReady에서 발생해야합니다.

적절한 시간에지도를 조작 한 예로지도의 카메라가 올바르게 설정된 경우에만 다음 코드에서 힌트를 얻을 수 있습니다.

public class YourMapFragment extends Fragment implements OnMapReadyCallback { 
... 
@Override 
public void onMapReady(GoogleMap googleMap) { 
mMap = googleMap; 
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(currentPosition,16)); 

    mMap.addMarker(new MarkerOptions() 
      .position(currentPosition) 
      .snippet("Lat:" + lat + "Lng:" + log)); 
} 

    ... 
    }
