需要打开手机的gps开关，正常的授权也要有

判断当前设备是否打开gps开关

 checkOpenGPSServiceByAndroid  () {
     let system = uni.getSystemInfoSync();// 获取系统信息
     if (system.platform === 'android') { // 判断平台
         var context = plus.android.importClass("android.content.Context");
         var locationManager = plus.android.importClass("android.location.LocationManager");
         var main = plus.android.runtimeMainActivity();
         var mainSvr = main.getSystemService(context.LOCATION_SERVICE);
         if (!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)) {
             uni.showModal({
                 title: '提示',
                 content: '请打开定位服务功能',
                 showCancel: false, // 不显示取消按钮
                 success() {
                     if (!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)) {
                         var Intent = plus.android.importClass('android.content.Intent');
                         var Settings = plus.android.importClass('android.provider.Settings');
                         var intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); 
                         main.startActivity(intent); // 打开系统设置GPS服务页面
                     }
                 }
             });
         }
     } 
 },

获取当前定位，经纬度转地址

getnow() {
    uni.getLocation({
        type: 'wgs84',
        geocode: true,
        success: (res) =>{
            let point = new plus.maps.Point(res.longitude, res.latitude);
            plus.maps.Map.reverseGeocode(
                point, {},
                (event) =>{
                    let address = event.address; // 转换后的地理位置
                    let point = event.coord; // 转换后的坐标信息
                    let coordType = event.coordType; // 转换后的坐标系类型
                    let reg = /.+?(省|市|自治区|自治州|县|区)/g;
                    let addressList = address.match(reg).toString().split(",");
                    console.log(addressList,'位置信息')
                }
            )
        }
    });
},
