android - SupportMapFragment - 二进制 xml 文件行 #2 : Error inflating class fragment

Question

我有一个扩展 FragmentActivty 的主类和扩展 SupportMapFragment 的 CustomMapFragment，当我将我的 customMapFragment 调用到 FragmentActivity 中时，我在 logCat 看到这个错误。

LogCat 结果:

主要 Activity :

public class MainActivity extends FragmentActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

            ...

    CustomMapFragment fragment = new CustomMapFragment (getApplicationContext(),this);
         getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, fragment ).commit();

           ...      
}

自定义 map fragment :

public class CustomMapFragment extends SupportMapFragment implements ConnectionCallbacks,OnConnectionFailedListener,LocationListener  {

private LocationClient locationClient;
private LocationRequest locationRequest;
private GoogleMap map;
FragmentActivity activity;
private Context context;
View view;

public CustomMapFragment (Context context,FragmentActivity activity){
    this.context = context;
    this.activity = activity;
}

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

    super.onCreateView(inflater, container, savedInstanceState);

    try {
        view = inflater.inflate(R.layout.map_layout, container,false);


        SupportMapFragment suppFragManager = (SupportMapFragment)activity.getSupportFragmentManager().findFragmentById(R.id.map);
        map = suppFragManager.getMap();

        locationClient = new LocationClient(context,this,this);

        locationRequest = LocationRequest.create();
        locationRequest.setInterval(9000);
        locationRequest.setFastestInterval(900);
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        return view;
    } catch (Exception e) {
        Log.d("ERROR", e.getMessage());
        e.printStackTrace();
    }

    return null;

}

...

map 布局:

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

安卓 list 文件:

<uses-sdk
    android:minSdkVersion="12"
    android:targetSdkVersion="18" />


<permission

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

    ...

 </application>

注意:我在这个类中使用 android.support.v4 库

Answer 1

public class CustomMapFragment extends SupportMapFragment

所以，CustomMapFragment 是一个 SupportMapFragment...

view = inflater.inflate(R.layout.map_layout, container,false);

...您正试图将 另一个 SupportMapFragment 膨胀到其中。

这不会很好地工作。

Either CustomMapFragment 扩展 SupportMapFragment(并删除其 onCreateView() 加上 map_layout.xml ) 或使用您的map_layout.xml。不要两者都做。
