MapView를 확장하는 데 문제가 있습니다.

Question

Hello, MapView에있는 문서를 통해 내 액티비티에 MapView를 추가 할 것입니다.

활동을 시작하면 MapView에서 인플레이션 오류가 발생합니다. 여기

내 레이아웃 XML에서지도보기이다 : 여기

<com.google.android.maps.MapView 
    android:id="@+id/mymap" 
    android:layout_width="fill_parent" 
    android:layout_height="200dip" 
    android:clickable="true" 
    android:apiKey="withheld" 
    /> 

내 MapActivity의 코드 (클래스라는 ActivityDetails하고 MapActivity 확장) 클래스 : 여기

MapView mMap; 
    mMap = (MapView) findViewById(R.id.mymap); 
    mMap.setBuiltInZoomControls(true); 

오류입니다 :

나는 말할 수있는 한, 문서화. 빌드 타겟을 Google API로 설정했고 Manifest에 uses-library 태그를 추가했습니다. Google API 타겟을 사용하는 에뮬레이터에서 실행 중입니다 ...

Answer 1

layout_details.xml 사용 layout.xml로 된 setContentView()를 호출해야 MapActivity를 확장 클래스 setContentView 다음에 super.onCreate()를 호출합니다.) MapActivity.

Answer 2

잘못된 XML을 사용하고 있습니다. 당신의지도보기

은이

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 
    <com.google.android.maps.MapView 
    android:id="@+id/racemap" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_x="0px" 
    android:enabled="true" 
    android:clickable="true" 
    android:apiKey="blahblahblah" /> 
</LinearLayout> 

같은 물건을 포함하는 XML 그래서 대신에 사용 문제는 내가이었다
