Play 스토어에서 동일한 탭 레이아웃을 시도하고 있습니다. androidhive의 조각과 viewpager를 사용하여 탭 레이아웃 을 표시해야합니다 . 그러나 Google지도 v2 를 구현할 수 없습니다 . 이미 몇 시간 동안 인터넷을 검색했지만 그 방법에 대한 자습서를 찾을 수 없습니다. 어떤 분이 방법을 보여 주시겠습니까?
답변
이 코드를 사용하여 ViewPager, Fragment 또는 Activity 내 어디에서나 MapView를 설정할 수 있습니다.
Google for Maps의 최신 업데이트에서는 조각에 대해 MapView 만 지원됩니다. MapFragment & SupportMapFragment가 작동하지 않습니다. 내가 틀렸을 수도 있지만 이것이 MapFragment & SupportMapFragment를 구현하려고 시도한 후에 본 것입니다.
파일의지도를 표시하기위한 레이아웃을 설정 location_fragment.xml
:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
이제 파일에 맵을 표시하기 위해 Java 클래스를 코딩합니다 MapViewFragment.java
.
public class MapViewFragment extends Fragment {
MapView mMapView;
private GoogleMap googleMap;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.location_fragment, container, false);
mMapView = (MapView) rootView.findViewById(R.id.mapView);
mMapView.onCreate(savedInstanceState);
mMapView.onResume(); // needed to get the map to display immediately
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
mMapView.getMapAsync(new OnMapReadyCallback() {
@Override
public void onMapReady(GoogleMap mMap) {
googleMap = mMap;
// For showing a move to my location button
googleMap.setMyLocationEnabled(true);
// For dropping a marker at a point on the Map
LatLng sydney = new LatLng(-34, 151);
googleMap.addMarker(new MarkerOptions().position(sydney).title("Marker Title").snippet("Marker Description"));
// For zooming automatically to the location of the marker
CameraPosition cameraPosition = new CameraPosition.Builder().target(sydney).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
}
});
return rootView;
}
@Override
public void onResume() {
super.onResume();
mMapView.onResume();
}
@Override
public void onPause() {
super.onPause();
mMapView.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
mMapView.onDestroy();
}
@Override
public void onLowMemory() {
super.onLowMemory();
mMapView.onLowMemory();
}
}
마지막으로 Google Cloud Console에 앱을 등록하여 앱의 API 키를 가져와야 합니다. 앱을 기본 Android 앱으로 등록하십시오.

GoogleMap
조각 에 사용하려는 경우이 줄을 사용할 수 있습니다 .
<fragment
android:id="@+id/map"
android:layout_width="wrap_content"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
GoogleMap mGoogleMap = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map)).getMap();
답변
getMapAsync
더 이상 사용되지 않는 최신 항목 .
1. 매니페스트 확인
<meta-data android:name="com.google.android.geo.API_KEY" android:value="xxxxxxxxxxxxxxxxxxxxxxxxx"/>
에서 앱을 등록하면 앱의 API 키를 얻을 수 있습니다 Google Cloud Console
. 앱을 기본 Android 앱으로 등록
2. 조각 레이아웃 .xml에서 FrameLayout (fragment 아님)을 추가하십시오.
<FrameLayout
android:layout_width="match_parent"
android:layout_height="250dp"
android:layout_weight="2"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/mapwhere" />
또는 원하는 높이
3. 조각의 onCreateView에서
private SupportMapFragment mSupportMapFragment;
mSupportMapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.mapwhere);
if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
mSupportMapFragment = SupportMapFragment.newInstance();
fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
}
if (mSupportMapFragment != null)
{
mSupportMapFragment.getMapAsync(new OnMapReadyCallback() {
@Override public void onMapReady(GoogleMap googleMap) {
if (googleMap != null) {
googleMap.getUiSettings().setAllGesturesEnabled(true);
-> marker_latlng // MAKE THIS WHATEVER YOU WANT
CameraPosition cameraPosition = new CameraPosition.Builder().target(marker_latlng).zoom(15.0f).build();
CameraUpdate cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition);
googleMap.moveCamera(cameraUpdate);
}
}

여기 내가 세부적으로 한 일 :
여기에서 당신은 구글지도 API 키를 얻을 수 있습니다
대안적이고 간단한 방법
먼저 Google 계정에 로그인하고 Google 라이브러리를 방문 하여 Google Maps Android API를 선택하십시오.
android studio 기본 맵 활동에서 발견 된 종속성 :
compile 'com.google.android.gms:play-services:10.0.1'
아래와 같은 응용 프로그램에서 안드로이드 mainifest 파일에 키를 넣으십시오.
AndroidMainifest.xml에서 다음과 같이 변경하십시오.
// required permission
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
// google map api key put under/inside <application></application>
// android:value="YOUR API KEY"
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="AIzasdfasdf645asd4f847sad5f45asdf7845" />
조각 코드 :
public class MainBranchFragment extends Fragment implements OnMapReadyCallback{
private GoogleMap mMap;
public MainBranchFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view= inflater.inflate(R.layout.fragment_main_branch, container, false);
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.main_branch_map);
mapFragment.getMapAsync(this);
return view;
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
LatLng UCA = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(UCA).title("YOUR TITLE")).showInfoWindow();
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(UCA,17));
}
}
당신은 xml 조각 :
<fragment
android:id="@+id/main_branch_map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.googlemap.googlemap.MapsActivity" />

됩니다. 탭을 초기화하는 클래스를 의미합니다. 이것은 코드입니다 :
