推荐答案

有一个看的 HTTP：//$c$c.google.com/p/gwt-google-apis/issues/detail ID = 381＃C53

在当前状态下，有没有小部件，但你可以在此期间使用 SimplePanel ：

In its current state, there's no Widget, but you could use a SimplePanel in the mean time:

SimplePanel mapWidget = new SimplePanel();
// add the widget to a parent widget, then:
GoogleMap map = GoogleMap.create(mapWidget.getElement());

或者如果你使用UiBinder的：

or if you use UiBinder:

<div ui:field='mapElement'></div>

@UiField DivElement mapElement;

...

GoogleMap map = GoogleMap.create(mapElement);

您可以再使用<一个href=\"http://gwt-google-apis.google$c$c.com/svntrunk/javadoc/maps/3.8/com/google/maps/gwt/client/DirectionsService.html\"相对=nofollow> 为DirectionsService 规划路线，并在<一个href=\"http://gwt-google-apis.google$c$c.com/svntrunk/javadoc/maps/3.8/com/google/maps/gwt/client/geometry/Spherical.html#computeDistanceBetween%28com.google.maps.gwt.client.LatLng,%20com.google.maps.gwt.client.LatLng%29\"相对=nofollow> com.google.maps.gwt.client.geometry 包来计算两点之间的距离。

You can then use the DirectionsService to get directions, and the com.google.maps.gwt.client.geometry package to compute distances between points.

该API被自动从JavaScript生成的​​，它应该是非常相似，你就可以轻松地适应JS的例子，你在网上的GWT绑定上找到。

The API being automatically generated from JavaScript, it should be similar enough that you'll be able to easily adapt JS examples you find on the web to the GWT bindings.
