如何获取v2 android地图的地图中心? [英] How to get center of map for v2 android maps?

问题描述

在Android版 v1 的Google Maps中，MapView提供了一种便捷的方法: getMapCenter().现在，我无法弄清楚如何使用此api的 v2 来获取地图中心.我已经仔细阅读过API文档，但是没有提及这种功能.请告知.

In Google Maps for Android v1, MapView had a convenience method: getMapCenter(). Now I cannot figure out how to get map center with v2 of this api. I have perused the API documentation, but there is no mention of such a feature. Please advise.

谢谢， 伊戈尔(Igor)

Thanks, Igor

推荐答案

我遇到了同样的问题.看来您可以通过这种方式获得中心位置:

I had the same problem. It seems you can get the center this way:

mMap.getCameraPosition().target

其中，mMap是您的活动中的GoogleMap实例.这将返回一个LatLng对象，该对象基本上代表地图的中心.

where mMap is the GoogleMap instance from your activity. This will return a LatLng object which basically represents the center of the map.

请注意，GeoPoint类不再可用.

Note that the GeoPoint class is not available anymore.

根据 http://developer.android.com/reference/com/google/android/gms/maps/model/CameraPosition.html

目标是相机指向的位置". (我用示例代码对其进行了测试，对我来说还可以)

target is "The location that the camera is pointing at." (I tested it with the sample code and it worked okay for me)
