推荐答案

我假设您要在带有标记的地图视图上使用它.

I am assuming you want it on a map view with a marker.

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    class="com.google.android.gms.maps.MapFragment" />

这应该添加到您希望地图参与的活动的xml文件中. 然后在您的活动中，

This should be added to you xml file of the activity you want the Map to be in. Then in your activity,

GoogleMap googleMap;
MapFragment mapFragment;

在您的onCreate中将其初始化；

Initialize this in you onCreate;

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

，然后创建替代方法onMapReady()

@Override
public void onMapReady(GoogleMap gMap) {
    googleMap = gMap;
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    try {
        googleMap.setMyLocationEnabled(true);
    } catch (SecurityException se) {

    }

    //Edit the following as per you needs
    googleMap.setTrafficEnabled(true);
    googleMap.setIndoorEnabled(true);
    googleMap.setBuildingsEnabled(true);
    googleMap.getUiSettings().setZoomControlsEnabled(true);
    //

    LatLng placeLocation = new LatLng(***YOUR LAT***, ***YOUR LNG***); //Make them global
    Marker placeMarker = googleMap.addMarker(new MarkerOptions().position(placeLocation)
                  .title(***NAME OF PLACE HERE***));
    googleMap.moveCamera(CameraUpdateFactory.newLatLng(placeLocation));
    googleMap.animateCamera(CameraUpdateFactory.zoomTo(10), 1000, null);
}

我认为这应该给您您想要的.如果您还有其他需要，请发表评论.

I think that should give you what you want. Comment if you need anything else.
