Question

我正在开发一个Metro路由器应用程序，我想让用户只需按一下按钮即可获得最近的地铁站。我有一个Metro Stops（班加罗尔）的列表就是这个。

{

"Bangalore International Exhibition Center", "Jindal", "Manjunathnagar", "Nagasandra",
 "Dasarahalli", "Jalahalli", "Peenya Industry", "Peenya", "Yeswanthpur Industry", 
 "Yeswanthpur", "Sandal Soap Factory", "Mahalaxmi", "Rajajinagar", "Kuvempu Road", 
 "Srirampura", "Sampige Road", "Kempegowda Interchange", "Chikpet", "K R Market", 
 "National College", "Lalbagh", "South End Circle", "Jayanagar", "R V Road 
 Interchange", "Banashankari", "J P Nagar", "Puttenahalli", "Anjanapura Cross Road", 
 "Krishna Leela Park", "Vajrahalli", "Thaighattapura", "Anjanapura/NICE Junction", 
 "Kengeri", "R V College of Engineering", "Bangalore University Cross", "Rajarajeshwari 
 Nagar", "Nayandahalli", "Mysore Road", "Deepanjali Nagar", "Attiguppe", "Vijayanagar", 
 "Hosahall1i", "Magadi Road", "Sir M Vishweshwariah", "Vidhana Soudha", "M G Road 
 Interchange", "Trinity", "Halasuru", "Indiranagar", "S V Road", "Baiyyappanahalli", 
 "Jyotipura", "K R Puram", "Mahadevpura", "Garudacharpalya", "Doddanekkundi Induatrial 
 State", "Vishweshwariah Industrial State", "Kundanahalli", "Vydhehi Hospital", "Satya

 Nagar", "Chikkabegur", "Basapura Road", "Hosa Road", "Electronics City 1", 
 "Electronics City 2", "Huskur Road", "Hebbagodi", "Bommasandra"

}

现在，当我使用位置管理器获取当前用户位置时，这将是详细版本，如“Surya City，Chandapura，Bommasandra，Bangalore”。现在我想知道如何从位置经理那里获得“Bommasandra”，因为这是Metro的停止。

如何从位置管理器获取结果后从数据库中获取最近的地铁站点。请帮忙。提前完成。

Answer 1

我建议，首先，您需要按照接近Metro Stops的顺序排列所有Metro Stops列表，然后按List<String> AllRoute排列，现在您必须解析包含特定Metro Stop的字符串从位置管理器类，您还可以将整个字符串与AllRoute列表项进行比较。从所有Metro Stops（AllRoute）列表中比较Metro Stop，并显示列表中用户的下3-4个站点，因为列表已按接近Metro Stop排序。

Answer 2

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

如何根据需要使用位置管理器
