지도를로드 할 때 MapView 메뉴 항목이 충돌 함

Question

내 메뉴에서지도 항목을 선택하면 내 앱이 충돌합니다. 나는 두 가지 중 하나를하고 있다고 생각한다. 1 - 내 메뉴 스위치 문에서 새 활동 (지도)을 올바르게 호출하지 않습니다. 2 - 내 맵 활동이 올바르게 구성되지 않았습니다.

FriendsApp.java는 (I 불필요한 비트 제외) :

이

public class FriendApp extends Activity { 
/** Called when the activity is first created. */ 


WebView mWebView; 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    mWebView = (WebView) findViewById(R.id.webview); 
    mWebView.getSettings().setJavaScriptEnabled(true); 
    mWebView.loadUrl("http://example.com/myfrienddash.php"); 

    mWebView.setWebViewClient(new FriendWebViewClient()); 
} 

//Tell main menu what to do when elements are clicked 
@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    switch (item.getItemId()) { 
    case FRIENDS: 
    mWebView.loadUrl("http://example.com/myfrienddash2.php"); 
     return true; 
    case MAP: 
     Intent friendMap = new Intent(FriendApp.this, FriendMaps.class); 
     startActivity(friendMap); 
     return true; 
    case SEARCH: 
    mWebView.loadUrl("http://example.com/myfrienddash3.php"); 
    return true; 
    case INFO: 
    mWebView.loadUrl("http://example.com/myfrienddash4.php"); 
    return true; 
    case QUIT: 
    finish(); 
    return true; 
    default: 
     return super.onOptionsItemSelected(item); 
    } 
}} 

FriendMaps.java :

public class FriendMaps extends MapActivity { 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.mapview); 

    MapView mapView = (MapView) findViewById(R.id.mapview); 
    mapView.setBuiltInZoomControls(true); 

    List<Overlay> mapOverlays = mapView.getOverlays(); 
    Drawable drawable = this.getResources().getDrawable(R.drawable.androidmarker); 
    BuoyItemizedOverlay itemizedoverlay = new BuoyItemizedOverlay(drawable, mapView.getContext()); 

    double longitude = 44.5; 
    double latitude = -63.4; 

GeoPoint point = new GeoPoint((int)(longitude * 1E6), 
    (int)(latitude * 1E6)); 
OverlayItem overlayitem = new OverlayItem(point, "what you talking aboot", "eh!"); 

itemizedoverlay.addOverlay(overlayitem); 
    mapOverlays.add(itemizedoverlay); 
} 

//Not using route feature so return false (must be set) 
@Override 
protected boolean isRouteDisplayed() { 
    // TODO Auto-generated method stub 
    return false; 
} 
} 

나는 현재 단지 정적으로 어떤 좌표를 추가하고 그것을 작동하게 할 수 있습니다.

도움을 주시면 감사하겠습니다.

추가 매니페스트 :

Answer 1

귀하의 <activity> 요소는 <application> 요소 내에 있어야합니다.
