Question

我的变量中有两个位置点，我想显示这两个位置之间路线的地图。我只想要一张谷歌地图，其中包含位置之间的路线。

Answer 1

要添加此库，请在gradle中添加依赖项

compile 'com.akexorcist:googledirectionlibrary:1.0.4'

示例代码

    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
        }
    });

在您的控制台中启用Google Maps Directions API

您可以将该代码传输到地图侦听器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());
                }
            });
}

在Android中使用谷歌地图创建一个活动，以显示两个位置之间的路线
