Question

我是Android的谷歌地图新手。我只是在片段中尝试了简单的谷歌地图，我停止了工作。也许这个问题与this相同，但我没有找到好的答案。我希望有一个人可以帮助我。这个java代码

public class MenujuStasiun extends Fragment {

    public MenujuStasiun() {
    }

    private GoogleMap googleMap;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.mstasiun, container, false);

        try {
            // Loading map
            initilizeMap();

        } catch (Exception e) {
            e.printStackTrace();
        }

        return rootView;
        }

    private void initilizeMap() {
        if (googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.map)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getActivity(),
                        "Sorry! unable to create maps",      Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }

    @Override
    public void onResume() {
        super.onResume();
        initilizeMap();
    }

}

这个mstasiun.xml

<?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" >

    <fragment
        android:id="@+id/map"
        class="com.google.android.gms.maps.MapFragment"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

这是logcat错误

如果那只是你的xml，那么你真的不需要那个RelativeLayout。如果您使用class="com.google.android.gms.maps.MapFragment"，则实际上不需要android:name="com.google.android.gms.maps.MapFragment"。你缺少的是xmlns:map="http://schemas.android.com/apk/res-auto"

汇总：

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

您正在使用真实设备进行测试，对吗？您需要配置模拟器才能使其与Google Play服务配合使用。
