Question

我想在Android应用程序中为Google Map片段添加属性。我能正确找到地图吗？我将如何实施以下示例？源代码如下。

示例（我想添加类似内容）

@Override
public void onMapReady(GoogleMap map) {
    map.addMarker(new MarkerOptions()
        .position(new LatLng(0, 0))
        .title("Marker"));
}

fragment1_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#D70B0D"
    android:orientation="vertical" >

     <TextView
        android:id="@+id/textView6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="5dp"
        android:text="@string/textView6"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="#FFFFFF"
        android:textStyle="bold" />

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:layout_margin="5dp"/>

    <Button
        android:id="@+id/btnRespond"
        android:layout_width="250dp"
        android:layout_height="wrap_content"
        android:text="@string/btnRespond"
        android:layout_gravity="center"
        android:layout_marginBottom="5dp"
        android:layout_marginTop="5dp"
        android:textColor="#FFFFFF"
        android:textStyle="bold"
        android:background="@drawable/button_animation"
        android:padding="5dp"/>


</LinearLayout>

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

        View view = inflater.inflate(R.layout.fragment1_layout, container, false);

        Fragment map = (Fragment) getFragmentManager().findFragmentById(R.id.map);

        Button btn = (Button) view.findViewById(R.id.btnRespond);

        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(), "You Are Now Active! Swipe Left For Individual Details & Medical Information", Toast.LENGTH_LONG).show();
            }
        });

        return view; 
    }
}

将fragment投放到MapFragment方法中的onCreateView，然后像这样调用地图异步

MapFragment mapFragment = (MapFragment) getFragmentManager()
            .findFragmentById(R.id.map);
mapFragment.getMapAsync(this);

取自谷歌地图文档here

然后在加载地图时会自动调用OnMapReady。
