在android創建一個谷歌地圖的活動來顯示兩個位置之間的路線

Question

我有兩個位置點在我的變量，我想顯示一個地圖與這兩個位置之間的路線。 我只想要一個帶有位置之間路線的Google地圖。

Answer 1

您可以使用此 Android-GoogleDirectionLibrary

要添加該庫中的gradle產出增加的依賴作爲

compile 'com.akexorcist:googledirectionlibrary:1.0.4' 

示例代碼

GoogleDirection.withServerKey("YOUR_SERVER_API_KEY") 
      .from(new LatLng(37.7681994, -122.444538)) 
       .to(new LatLng(37.7749003,-122.4034934)) 
       .avoid(AvoidType.FERRIES) 
       .avoid(AvoidType.HIGHWAYS) 
       .execute(new DirectionCallback() { 
     @Override 
     public void onDirectionSuccess(Direction direction, String rawBody) { 
      if(direction.isOK()) { 
       // Do something 
Snackbar.make(btnRequestDirection, "Success with status : " + direction.getStatus(), Snackbar.LENGTH_SHORT).show(); 
       googleMap.addMarker(new MarkerOptions().position(origin)); 
      googleMap.addMarker(new MarkerOptions().position(destination)); 

      ArrayList<LatLng> directionPositionList = direction.getRouteList().get(0).getLegList().get(0).getDirectionPoint(); 
      googleMap.addPolyline(DirectionConverter.createPolyline(this, directionPositionList, 5, Color.RED)); 

     } 

      } else { 
       // Do something 
      } 
     } 

     @Override 
     public void onDirectionFailure(Throwable t) { 
      // Do something 
     } 
    });

1. 啓用谷歌地圖路線API在控制檯

2. 您可以將該代碼轉移到地圖監聽器EG。

   @Override 
       public void onMapClick(LatLng latLng) { 
        GoogleDirectionConfiguration.getInstance().setLogEnabled(true); 
         $key = getResources().getString(R.string.google_maps_key; 
   
        GoogleDirection.withServerKey($key)) 
         .from(mCurrLocationMarker.getPosition()) 
         .to(latLng) 
         .transportMode(TransportMode.DRIVING) 
         .transitMode(TransitMode.BUS) 
         .unit(Unit.METRIC) 
         .execute(new DirectionCallback() { 
          @Override 
          public void onDirectionSuccess(Direction direction, String rawBody) { 
   
           Log.d("GoogleDirection", "Response Direction Status: " + direction.toString()+"\n"+rawBody); 
   
           if(direction.isOK()) { 
            // Do something 
            Route route = direction.getRouteList().get(0); 
            Leg leg = route.getLegList().get(0); 
            ArrayList<LatLng> directionPositionList = leg.getDirectionPoint(); 
            PolylineOptions polylineOptions = DirectionConverter.createPolyline(getApplication(), directionPositionList, 5, Color.RED); 
            mMap.addPolyline(polylineOptions); 
           } else { 
            // Do something 
           } 
          } 
   
          @Override 
          public void onDirectionFailure(Throwable t) { 
           // Do something 
           Log.e("GoogleDirection", "Response Direction Status: " + t.getMessage()+"\n"+t.getCause()); 
          } 
         }); 
   }
