Google android maps v2 MetersToEquatorPixel [英] Google android maps v2 MetersToEquatorPixel

问题描述

我目前的任务是将Google Android maps v1应用程序转换为Google Android Maps V2应用程序。这个过程并不愉快（感谢谷歌）。

I am currently tasked with converting a Google Android maps v1 application over to Google Android Maps V2 application. The process is not a pleasant one (thanks google).

我的问题是，在之前的应用程序中，他们使用了一种称为您可以从Map的投影对象中获取metersToEquatorPixels 。

My problem is that in the previous application they used a nice little method of Google Android Maps v1 called metersToEquatorPixels that you could get from the Map's projection object.i.e.

int px =(int) (mapProjection.metersToEquatorPixels(radiusInMeters) * (1 / Math.cos(Math.toRadians(latitudeActual))));

但是，在谷歌Android地图V2中，我找不到这样一种方法。任何人都可以告诉我它在哪里，或者合适的替代品可能是什么？

However, in Google Android maps V2 there is not such a method I could find. Can anyone tell me where it is, or what a suitable replacement might be?

推荐答案

您不需要这样做，只需绘制一个圆圈，并以米为单位消除中心和半径

You dont need to do that, just draw a circle and pass away center and radius in meters

mMap.addCircle(new CircleOptions()
     .center(latLng)
     .radius(radiusInMeters)
     .fillColor(Color.BLUE));
