我想问题出在这节课上了

public class FracMap extends Fragment {
        View rootView;
       MapFragment mapView;
       // GoogleMap map;

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

        rootView=inflater.inflate(R.layout.frac_maps, container, false);
        GoogleMap mapa = ((MapFragment) getActivity().getFragmentManager()
                .findFragmentById(R.id.map)).getMap();
        return rootView;

    }

    public static FracMap map(){

        return new FracMap();
    }
}

manifest.xml

        View rootView;
       MapFragment mapView;

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

        rootView=inflater.inflate(R.layout.frac_maps, container, false);
        GoogleMap mapa = ((MapFragment) getActivity().getFragmentManager()
                .findFragmentById(R.id.map)).getMap();
        return rootView;

    }

    public static FracMap map(){

        return new FracMap();
    }
}

布局

public class FracMap extends Fragment {
        View rootView;
       MapFragment mapView;
       // GoogleMap map;

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

        rootView=inflater.inflate(R.layout.frac_maps, container, false);
        GoogleMap mapa = ((MapFragment) getActivity().getFragmentManager()
                .findFragmentById(R.id.map)).getMap();
        return rootView;

    }

    public static FracMap map(){

        return new FracMap();
    }
}

<?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"/>

---

在布局中使用此特定的

SupportMapFragment

类时，必须按如下方式处理

getSupportMapFragment（）

方法：

GoogleMap mapa = ((SupportMapFragment) getActivity().getSupportFragmentManager()
            .findFragmentById(R.id.map)).getMap();  

---

让我知道这是否有帮助。

请发布

R.layout.frac\u maps.xml

。是的，你是最好的：D，我是一个新手，非常感谢。没问题，我很高兴帮助@Gabo。愉快的编码。无需通过引用

活动

获取

碎片管理器

。您可以从

片段本身内部调用
getFragmentManager（）
。您确定@Emmanuel？因为如果使用类
com.google.android.gms.maps.SupportMapFragment
，则必须使用
getSupportFragmentManager（）
方法，而不是
getFragmentManager（）
。也许我错了，我会很高兴知道我的错误，但是我总是使用这个而不是其他。如果在
活动中调用该方法，就是这种情况。这里他在一个
片段中<代码>片段
有自己的
getFragmentManager（）
，如果是支持库
片段

，它将返回所说的

片段管理器

的支持库版本。
