android - 在 MapFragment 中膨胀类 fragment 时出错

Question

我的 MapFragment 有 xml 文件

<?xml version="1.0" encoding="utf-8"?>
<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

和 fragment 使用它:

public class CallistoMapFragment extends MapFragment {
private GoogleMap mMap;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.map_fragment, null);
    mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();
    setUpMap();
    return v;
}

private void setUpMap() {
    mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title(
            "Marker"));
}

} 尝试编译时出现错误

11-20 15:31:15.343: E/AndroidRuntime(10705): android.view.InflateException: Binary XML file line #6: Error inflating class fragment

android list 中的 API key 是正确的。怎么了？

使用:

XML:

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
         />

类

GoogleMap mMap;
SupportMapFragment mapFrag;

Now set it:

if (mMap == null) {
            mapFrag= (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
            mMap =  mapFrag.getMap();

            // Check if we were successful in obtaining the map.
            if (mMap != null) {
                // The Map is verified. It is now safe to manipulate the map.

            }
        }

还在 list 文件中添加此元标记。

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

<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="myApiKey"/>
