Question

我使用MapFragment来显示Google地图。我想我已经在代码中完成了所有工作，但地图并没有显示任何内容 enter image description here 我想这是API密钥问题。

这就是我得到它的方式：

使用此命令生成SHA1 Fingerprint： keytool -list -v -keystore /Users/[USERNAME]/[debug.keystore path] -alias androiddebugkey -storepass android -keypass android

在Google开发者控制台中创建了新项目，启用了Google Maps Api V2，在凭据中创建了新的Android密钥

这是我从谷歌开发者控制台获得的项目凭据： enter image description here

这是Manifest文件：

任何建议？

修改我在Xamarin上写作。如果有人需要，我的片段就在这里：

public class ContractorMapFragment : Fragment {
    View view;
    private static int layoutId;

    public override void OnActivityCreated(Bundle savedInstanceState) {
        base.OnActivityCreated(savedInstanceState);

        MapFragment mapFrag = (MapFragment)FragmentManager.FindFragmentById(Resource.Id.map);
        GoogleMap Map = mapFrag.Map;
        if (Map != null) {
            Map.MapType = GoogleMap.MapTypeNormal;
            Map.UiSettings.CompassEnabled = true;
            Map.MyLocationEnabled = true;
        }
    }

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        if (view != null) {
            ViewGroup parent = (ViewGroup)view.Parent;
            if (parent != null) {
                parent.RemoveView(view);
            }
        }

        try {
            if (layoutId == 0)
                layoutId = Resource.Layout.MapFragmentLayout;
            view = inflater.Inflate(layoutId, container, false);
        }
        catch (InflateException e) {

        }
        return view;
    }
}

观看：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<fragment
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    class="com.google.android.gms.maps.MapFragment" />

Xamarin正在使用不同的debug.keystore！

keytool -exportcert -alias androiddebugkey -keystore ~/.local/share/Xamarin/Mono\ for\ Android/debug.keystore | openssl sha1 -binary | openssl base64

这应该可以解决你的问题。
