android Google지도를 표시 할 수 없습니다

Question

안녕하세요 저는 Google지도에서 핀을 표시하고 끌어서 일부 소스 코드를 가져 오려고합니다. 이클립스로의 가져 오기가 성공했지만 내 장치에서지도를 실행할 수는 있지만 api key issue에 관한 것인가? 표시하기 위해 새로운 API 키를 생성해야합니까? 여기

내가 가져했습니다 프로젝트이다 .. 사람이 도움이 붙어있어

first one

도 여기에 두 번째 링크의 소스 코드입니다. 아이디어

Answer 1

에게 있습니다. 또한 따라야 할 다른 설정이 있습니다. 여기에 좋은 toutorial-입니다>Google map v2

이 편집 내가 제안 :

레이아웃 XML 내부

1. 는

사용 (즉 toutorial에 4.5th 단계를 activity_main.xml.)

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


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


</RelativeLayout> 

메인 클래스를 작성하여 'FragmentActivity'를 확장하십시오 (튜토리얼에서 4.6 번째 단계)

public class MainActivity extends FragmentActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main);// This line is all that you need to display a map. 

    } 
    } 

마지막으로 중요한 것은 AndroidManifest.xml입니다.

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="your_package" 
    android:versionCode="1"

콘솔에서 Google Maps Android API v2를 사용 설정 했습니까? 많은 사람들이 그것을 돌리는 것을 잊어 버린다. 왼쪽의 서비스를 선택하고 Google지도를 켜십시오. Android API v2
