Question

我在Akexorcist的谷歌地图方向api库上为方向绘制折线时遇到问题。即时通讯使用akexorcist库你可以在这里得到它：

Akexorcist网站： http://www.akexorcist.com/2015/12/google-direction-library-for-android-en.html

Github上： https://github.com/akexorcist/Android-GoogleDirectionLibrary

我有两个latlng对象（原点和目的地），我只需要创建一个多边形线来显示使用他的库的方向。错误显示：

java.lang.IndexOutOfBoundsException：索引1无效，大小为0

这是代码：

private void ListingNearbyDirection(final LatLng Origin, final LatLng Destination){
        String serverKey = "AIzaSyAGpF1Jedi8EEliwUPk************";

        GoogleDirection.withServerKey(serverKey)
                .from(Origin)
                .to(Destination)
                .transportMode(TransportMode.DRIVING)
                .alternativeRoute(true)
                .execute(new DirectionCallback() {
                    @Override
                    public void onDirectionSuccess(Direction direction, String rawBody) {
                        mMap.addMarker(new MarkerOptions().position(Origin));
                        mMap.addMarker(new MarkerOptions().position(Destination));
                        mMap.animateCamera(CameraUpdateFactory.newLatLng(Origin));
                        moveToCurrentLocation(Origin);

                        ArrayList<LatLng> directionPositionList = direction.getRouteList().get(0).getLegList().get(0).getDirectionPoint();
                        PolylineOptions polylineOptions = DirectionConverter.createPolyline(getApplicationContext(), directionPositionList, 5, Color.YELLOW);
                        mMap.addPolyline(polylineOptions);
                    }

                    @Override
                    public void onDirectionFailure(Throwable t) {

                    }
                });
    }

和onMapReady（）

LatLng origin = getLocationFromAddress(this, address);
            LatLng destination = new LatLng(Double.parseDouble(myLatitude), Double.parseDouble(myLongitude));
            ListingNearbyDirection(origin, destination);
