Google Maps API v2中的setBounds如何？ [英] How do setBounds in Google Maps API v2?

问题描述

我正在升级为Google Maps API v2编写的一些代码，并且希望设置地图的边界（顶部，左侧，底部，右侧），而不是中心。

I'm upgrading some code written for Google Maps API v2, and I wish to set the bounds of the map (top, left, bottom, right), rather than the centre.

我注意到有一个 GMap2.getBounds ，但我似乎无法找到一种方法，允许我设置边界。

I notice that there's a GMap2.getBounds but I can't seem to find a method which allows me to set the bounds.

如何在Google Maps中执行此操作？

推荐答案

找到在这里做一个setBounds的方法： http：/ /www.mymapofjapan.com/blog/setting-size-and-zoom-level-of-maps/

Found a way to do a setBounds here: http://www.mymapofjapan.com/blog/setting-size-and-zoom-level-of-maps/

var bounds = new GLatLngBounds; 
bounds.extend(new GLatLng( South, West )); 
bounds.extend(new GLatLng( North, East )); 
map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));

由于Google地图具有不连续的缩放级别，因此您可能无法将其设置为完全界限你想要的，所以你可能需要调用map.getBounds（）;之后向用户展示他们正在查看的实际边界。

Because Google Maps has discrete zoom levels you probably won't be able to set it to exactly the bounds you wanted, so you might need to call map.getBounds(); afterwards to show the user the actual bounds they are looking at.
