我已经阅读了很多关于这个问题的主题，但没有任何帮助。所以我想在 SupportMapFragment 中对 GoogleMap 进行操作。在 FragmentActivity 我在 onCreate 方法中初始化了地图

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.content_frame);

    // Initialize Google Maps Android API
    try {
        MapsInitializer.initialize(this);
    } catch (GooglePlayServicesNotAvailableException e) {
        e.printStackTrace();
    }
...

我的 MapFragment 的代码看起来就像这样

public class MapFragment extends SupportMapFragment {

private final String TAG = getClass().getSimpleName();


public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    return inflater.inflate(R.layout.map, null);
}

public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    GoogleMap gMap = this.getMap();

    Log.d(TAG,
            "getMap() " + ((gMap == null) ? "null" : gMap.toString()));

    // Setting Location and Zoom
    gMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(
            40.76793169992044f, -73.98180484771729f), 14.0f));
}

}

每次我使用 getMap 方法得到 null 时......有什么想法吗？

欧元：

将google play服务更新到最新版本后遇到类似问题。通过在清单中添加元数据解决了我的问题

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
