（七）高德地圖之路線導航

本節將要實現的功能是路線導航，確定出發點和到達的終點座標，兩點之間的路線導航。跟前幾篇一樣，上代碼

首先是類文件NaviActivity.java

    @Override
    public void onMapTypeChanged(int i) {

    }

    @Override
    public void onNaviViewShowMode(int i) {

    }
}

然後是佈局文件activity_navi.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.amap.api.navi.AMapNaviView
        android:id="@+id/navi_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"/>
</LinearLayout>

其中有實時導航和模擬導航

@Override
    public void onCalculateRouteSuccess(int[] ints) {
        //多路徑算路成功回調
//        mAMapNavi.startNavi(NaviType.EMULATOR);//模擬導航
        mAMapNavi.startNavi(NaviType.GPS);//實時導航
    }

步行導航和騎行導航與駕車導航就更改一句話就可以了

@Override
    public void onInitNaviSuccess() {
        //初始化成功
        /**
         * 方法: int strategy=mAMapNavi.strategyConvert(congestion, avoidhightspeed, cost, hightspeed, multipleroute); 參數:
         *
         * @congestion 躲避擁堵
         * @avoidhightspeed 不走高速
         * @cost 避免收費
         * @hightspeed 高速優先
         * @multipleroute 多路徑
         *
         *  說明: 以上參數都是boolean類型，其中multipleroute參數表示是否多條路線，如果爲true則此策略會算出多條路線。
         *  注意: 不走高速與高速優先不能同時爲true 高速優先與避免收費不能同時爲true
         */
        int strategy = 0;
        try {
            //再次強調，最後一個參數爲true時代表多路徑，否則代表單路徑
            strategy = mAMapNavi.strategyConvert(true, true, true, false, true);
        } catch (Exception e) {
            e.printStackTrace();
        }
        mAMapNavi.calculateDriveRoute(sList, eList, mWayPointList, strategy);//起始點座標、終點座標、途經點座標、strategy
//        mAMapNavi.calculateWalkRoute(new NaviLatLng(39.925846, 116.435765), new NaviLatLng(39.925846, 116.532765));//步行導航
//        mAMapNavi.calculateRideRoute(new NaviLatLng(39.925846, 116.435765), new NaviLatLng(39.925846, 116.532765));//騎行導航
    }

以上就實現了路線導航功能，實際開發我們需要根據實際需求來更改
