Question

您好我是Android编程的新手，我遵循了许多教程中的步骤，但我只设法显示谷歌地图，它只显示模拟器和设备上的图块。非常感谢提前！

Heres my Manifest：

    android:value="AIzaSyCFLLz6m3N1WEKNG6KnwvoQvMBTC4r9AzA"/>
          </application>
    </manifest>

我的xml（我很确定我有正确的API密钥）：

<?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">

 <com.google.android.maps.MapView 
    android:id="@+id/mapView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:enabled="true"
    android:clickable="true"
    android:apiKey="***************"
    />

 </RelativeLayout>

和我的java代码：

 public class WebMapViewActivity extends MapActivity {

 @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mapview);
        getActionBar();
        ActionBar actionBar = getActionBar();
        actionBar.setIcon(R.drawable.ic_menu_mapmode);
        actionBar.setTitle("Map");

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

 List<Overlay> mapOverlays = mapView.getOverlays();
 Drawable drawable = this.getResources().getDrawable(R.drawable.ic_launcher);
 HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable,this);
 GeoPoint point = new GeoPoint(133339,-10390584);
 OverlayItem overlayitem = new OverlayItem(point, "Hello!","This is Biosensors Interventional Singapore !");

 itemizedoverlay.addOverlay(overlayitem);
 MapController mapController = mapView.getController();
 mapController.setCenter(point);

 mapOverlays.add(itemizedoverlay);
 }
 @Override
 protected boolean isRouteDisplayed()
 {
 return false;
 }

        }

Answer 1

我可以看到你在这段代码中混合了API v1和v2。

在你的布局中删除mapview并添加：

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/map"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:name="com.google.android.gms.maps.MapFragment"/>

并扩展Activity而不是MapActivity（如果您使用支持库，则扩展FragmentActivity）。

您可以在Maps API page

上看到更多信息

正如@DavidBriggs所说，你正在混合来自API V1和V2的代码。

如果您想使用Google Maps API V2查看所有清单配置，那么这是我写的关于如何添加的博客文章：

Google Map API V2 to your App.
