1.获取当前的地理位置

type：'wgs84'返回gps坐标，无法获取到address

           'gcj02'返回国测局坐标，可以获取到address

uni.getLocation({

    geocode: true,

    type: 'gcj02',

    success: (res) => {

          this.latitude = res.latitude;

           this.longitude = res.longitude;

           //地址信息（仅App端支持，需配置geocode为true）

            this.current_address = res.address.province + res.address.city + res.address .district + res.address.street + res.address.streetNum + res.address.poiName;

             this.navigaToShop();

    }

})

2.判断是否安装高德app，安装并唤起app进行导航

navigaToShop(item) {

    let shop_latitude = item.latitude;//目的地纬度

    let shop_longtude = item.longitude;//目的地经度

     let shop_address =item.stationname;//目的地地址

     let current_latitude = this.latitude;//当前纬度

     let current_longitude = this.longitude;//当前经度

     var packageName = 'com.autonavi.minimap';

     var main = plus.android.runtimeMainActivity();

     var packageManager = main.getPackageManager();

     var PackageManager = plus.android.importClass(packageManager);

     var packageInfo = packageManager.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);

      if (packageInfo)

       {

                   var Uri = plus.android.importClass("android.net.Uri");

                   var url = "amapuri://route/plan?sourceApplication=maxuslife" + "&sid=A&slat=" + current_latitude + "&slon=" + current_longitude + "&sname=" + this .current_address + "&did=B&dlat=" + shop_latitude + "&dlon=" + shop_longtude + "&dname=" + shop_address + "D10&dev=0&t=0";

                 var Intent = plus.android.importClass('android.content.Intent');

                 var intent = new Intent();

                 intent.setAction(Intent.ACTION_VIEW);

                 intent.addCategory(Intent.CATEGORY_DEFAULT);

                 var uri = Uri.parse(url);

                  //将功能Scheme以URI的方式传入

                 data intent.setData(uri);

                  intent.setPackage("com.autonavi.minimap");

                  var main = plus.android.runtimeMainActivity();

                  main.startActivity(intent);

     } else {

        uni.showToast({ icon: 'none', title: `未安装高德导航APP，请先安装` })

} },
