现在，当我使用location Manager获得当前用户位置时，它将是一个详细的版本，比如Surya City、Chandapura、Bommasandra、Bangalore。现在我想知道如何从位置经理那里得到Bommasandra，因为这是地铁站

以及从location manager获得结果后如何从数据库中获取最近的地铁站。请帮忙。Thanx提前到达。

我建议，首先，你需要按照接近地铁站的顺序将所有地铁站的列表按升序排列，比如说，你将它们排列在列表AllRoute中，现在，您必须从Location Manager类解析包含特定地铁站的字符串，您还可以将整个字符串与AllRoute列表的项目进行比较。比较所有地铁站AllRoute列表中的地铁站，并向用户显示列表中接下来的3-4个站，因为列表已经按照接近地铁站的顺序进行了排序。

我认为，在您的位置数组中，您可以将lat、lng与每个位置相关联。然后使用当前位置lat，lng，您可以找到最近的位置

检查这是否有帮助。。这很有帮助，但是如何在地图上添加标记呢。？正如你所看到的，我有一些特定的地方需要我的标记。请帮忙。
