안드로이드 서랍 예제, 구글 맵 조각 구현 방법

2014-04-14 4 views

사실 안드로이드 서랍 예제에서 Google 맵을 구현하려고합니다. 기본적으로 첫 번째 메뉴 항목을 선택하여 맵을 표시하고 싶습니다. 제공된 모든 예제는 모든 맵에 대해 FragmentActivity를 사용하고 있으며, 서랍에서 사용하는 Fragment 클래스를 확장하여 Map에 적합한 클래스를 만듭니다. 출시에 불행하게도 앱 충돌 :안드로이드 서랍 예제, 구글 맵 조각 구현 방법

fragment 클래스 내에서 맵을 사용하려면 MapView을 사용해야합니다. 다음과 같이 당신이 좋은 결과를 볼 수 있습니다 이것을 시도

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <com.google.android.gms.maps.MapView 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

</RelativeLayout>

아래 xml 파일을 붙여 넣기 코드에서

MapView mapView; 

GoogleMap googleMap; 

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    { 
     View view = inflater.inflate(R.layout.your_layout_name, container, false); 

     mapView = (MapView) view.findViewById(R.id.map); 

      mapView.onCreate(savedInstanceState); 

      if(mapView!=null) 
      { 
       googleMap = mapView.getMap(); 

       googleMap.getUiSettings().setMyLocationButtonEnabled(false); 

       googleMap.setMyLocationEnabled(true); 

       googleMap.getUiSettings().setZoomControlsEnabled(true); 
      } 

     return view; 

    } 

    @Override 
    public void onResume() 
    { 
     mapView.onResume(); 

     super.onResume(); 
    } 
    @Override 
    public void onDestroy() 
    { 
     super.onDestroy(); 

     mapView.onDestroy(); 
    } 
    @Override 
    public void onLowMemory() 
    { 
     super.onLowMemory(); 

     mapView.onLowMemory(); 
    }

...

남자, 대답은 완벽했습니다! –

업데이트합니다 위치 조각의 XML :

<?xml version="1.0" encoding="utf-8"?> 
<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
      android:id="@+id/map" 
      android:name="com.google.android.gms.maps.MapFragment" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent"/>

조각에 OnMapReadyCallback 인터페이스, 예를 들면, onMapReady(GoogleMap map) 방법으로지도를 구성하는 코드를 작성 :

public void onMapReady(GoogleMap map) { 
    googleMap.addMarker(new MarkerOptions() 
      .position(new LatLng(0, 0)) 
      .title("Marker")); 

    googleMap.setMyLocationEnabled(true); 
    googleMap.animateCamera(CameraUpdateFactory.zoomTo(17.0f)); 
}

나는 당신을 위해 도움이 될 것입니다 희망!
