React-native 高德定位

目前看了下很多高德定位的,基本都是监听写的,每次调用会使用多次.
所以自己写了一个封装适合ios和安卓. 还有获取第三方地图的跳转功能
只调用一次定位,不会重复调用,有使用的朋友请自行获取.
至于高德地图的配置还请自行去高德官网查看,我这里只放出源码

package 代码

import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;

    @Override
    public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {
        return Arrays.<NativeModule>asList(new MyLocationModule(reactContext));
    }
}

最后不要忘记在mainapplication 里添加注册进去

 @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
       ...
        new MyLocationPackage()
       ...

    }

好了下面是js 代码的调用方式

//记得要导入navtive  var MyLocation = NativeModules.MyLocation
 MyLocation.addEventCrood('定位', (error, location) => {
      alert(location);
    })

下面是第三方地图导航的使用

let lat = '31.0913734181';   // ---纬度 31.091769
let name = '上海市人民广场';//
//这里的ActionSheet 是自定义的一个弹窗,大家可以自己去找  我只是自己封装了下,使用方法和Facebook的一样

MyLocation.findEvents(lon, lat, name, (events) => {
      events.map((index, item) => {
        array.push(index.title);
      })
      if (array.length > 2) {

          (buttonIndex) => {
            //跳到原生方法对应的app地图导航内
            MyLocation.addEvent(events[buttonIndex].title, events[buttonIndex].url, lon, lat, name);//lat是经度，，，log是维度
          });
      } else if (array.length == 2) {
        if (events.length == 2 && events[0].url == 'ios') {
