React Native GeoLocation 不适用于 Android [英] React Native GeoLocation is not working on Android

问题描述

谁能确认 React Native Geolocation 是否真的在 Android 上运行?我在使用 getCurrentPosition() 方法时定位请求超时，并且在使用 watchPosition() 方法时没有错误消息.

Can anyone confirm if React Native Geolocation is actually working on Android? I am stuck with location request timed out while using getCurrentPosition() method and no error message while using watchPosition() method.

我已在 AndroidManifest.xml 上添加了所需的权限 (FINE LOCATION)，并且应用程序允许位置权限.

I have added the required permission (FINE LOCATION) on AndroidManifest.xml and location permission is allowed for the app.

这是我的实现:

componentWillMount() {
 navigator.geolocation.getCurrentPosition((position) => {
        console.log('+++++++');
        console.log(position.coords.longitude);
        this.setState({
          longitude: position.coords.longitude,
          error: null,
        });
      },
      (error) => {
        console.log(error);

      },

    );
}

反应原生版本:0.42

React Native Version : 0.42

推荐答案

你需要把enableHighAccuracy改为false

you need to change enableHighAccuracy to false

const LATITUDE_DELTA = 0.0922;
const LONGITUDE_DELTA = LATITUDE_DELTA * ASPECT_RATIO; 

this.state = {
        region:{}}

 navigator.geolocation.getCurrentPosition(
                (position) => {
                    console.log(position);
                    this.setState({
                        region: {
                            longitude: position.coords.longitude,
                            latitude: position.coords.latitude,
                            latitudeDelta: LATITUDE_DELTA,
                            longitudeDelta: LONGITUDE_DELTA
                        }
                    });
                },
                (error) => console.log(new Date(), error),
                {enableHighAccuracy: false, timeout: 10000, maximumAge: 3000}
            );
