Android - 如何獲得從一個地方到另一個地方的預計駕駛時間？

Question

我需要找到從一個地方到另一個地方的估算駕駛時間。我對這兩個地方都有經緯度，但我不知道該怎麼做。是否有任何API。 幫助謝謝。

Answer 1

是的，你可以得到時間和距離值以及許多像駕駛，步行等模式中的方向細節。你從谷歌的方向API服務得到了

Answer 2

Location location1 = new Location(""); 
    location1.setLatitude(lat); 
    location1.setLongitude(long); 

    Location location2 = new Location(""); 
    location2.setLatitude(lat); 
    location2.setLongitude(long); 

    float distanceInMeters = location1.distanceTo(location2); 

編輯：

//For example spead is 10 meters per minute. 
    int speedIs10MetersPerMinute = 10; 
    float estimatedDriveTimeInMinutes = distanceInMeters/speedIs10MetersPerMinute; 

也請看到這一點，如果上面沒有作品你：

Answer 3

也可以使用 http://maps.google.com/maps?saddr= {START_ADDRESS} & DADDR = {的destination_address}

它將方向細節得到具有距離和時間沿位置

http://maps.google.com/maps?saddr=79.7189,72.3414&daddr=66.45,74.6333&ie=UTF8&0&om=0&output=kml

Answer 4

Calculate Distance:- 
    float distance; 
      Location locationA=new Location("A"); 
      locationA.setLatitude(lat); 
      locationA.setLongitude(lng); 

      Location locationB = new Location("B"); 
      locationB.setLatitude(lat); 
      locationB.setLongitude(lng); 

      distance = locationA.distanceTo(locationB)/1000; 

      LatLng From = new LatLng(lat,lng); 
      LatLng To = new LatLng(lat,lng); 

      Calculate Time:- 
      int speedIs1KmMinute = 100; 
      float estimatedDriveTimeInMinutes = distance/speedIs1KmMinute; 
       Toast.makeText(this,String.valueOf(distance+ 
"Km"),Toast.LENGTH_SHORT).show(); 
      Toast.makeText(this,String.valueOf(estimatedDriveTimeInMinutes+" Time"),Toast.LENGTH_SHORT).show();

Answer 5

作爲已經described by Praktik，您可以使用Google的路線API來估計所需的時間從一個地方到另一個地方考慮​​路線和交通。但是，您不必使用Web API並構建自己的包裝器，而是使用Google自己提供的Java implementation，它可以通過Maven/gradle存儲庫獲得。

1. Add the google-maps-services to your app's build.gradle：

   dependencies { 
       compile 'com.google.maps:google-maps-services:0.2.5' 
   } 
   

2. 執行請求和提取的持續時間：

   // - Put your api key (https://developers.google.com/maps/documentation/directions/get-api-key) here: 
   private static final String API_KEY = "AZ.." 
   
   /** 
   Use Google's directions api to calculate the estimated time needed to 
   drive from origin to destination by car. 
   
   @param origin The address/coordinates of the origin (see {@link DirectionsApiRequest#origin(String)} for more information on how to format the input) 
   @param destination The address/coordinates of the destination (see {@link DirectionsApiRequest#destination(String)} for more information on how to format the input) 
   
   @return The estimated time needed to travel human-friendly formatted 
   */ 
   public String getDurationForRoute(String origin, String destination) 
       // - We need a context to access the API 
       GeoApiContext geoApiContext = new GeoApiContext.Builder() 
        .apiKey(apiKey) 
        .build(); 
   
       // - Perform the actual request 
       DirectionsResult directionsResult = DirectionsApi.newRequest(geoApiContext) 
         .mode(TravelMode.DRIVING) 
         .origin(origin) 
         .destination(destination) 
         .await(); 
   
       // - Parse the result 
       DirectionsRoute route = directionsResult.routes[0]; 
       DirectionsLeg leg = route.legs[0]; 
       Duration duration = leg.duration; 
       return duration.humanReadable; 
   } 
   

爲簡單起見，此代碼不處理異常，錯誤的情況下（例如，沒有路線發現 - > routes.length == 0），也不會打擾多個route或leg。出發地和目的地也可以直接設置爲LatLng實例（見DirectionsApiRequest#origin(LatLng)和DirectionsApiRequest#destination(LatLng)
