Hec*_*888 2 reactjs react-native react-native-maps
我正在使用react-native-maps并且使用此代码得到纬度和经度:
callLocation(that) {
navigator.geolocation.getCurrentPosition(
position => {
const currentLongitude = JSON.stringify(position.coords.longitude);
const currentLatitude = JSON.stringify(position.coords.latitude);
that.setState({ currentLongitude: currentLongitude });
that.setState({ currentLatitude: currentLatitude });
},
error => alert(error.message),
{ enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 }
);
that.watchID = navigator.geolocation.watchPosition(position => {
console.log(position);
const currentLongitude = JSON.stringify(position.coords.longitude);
const currentLatitude = JSON.stringify(position.coords.latitude);
that.setState({ currentLongitude: currentLongitude });
that.setState({ currentLatitude: currentLatitude });
});
}

这是我的地图视图代码:
<MapView
style={styles.map}
initialRegion={{
latitude: this.state.currentLatitude,
longitude: this.state.currentLongitude,
latitudeDelta: 0.0922,
longitudeDelta: 0.0421
}}
/>

当我将这个纬度和经度粘贴到我的代码中时,出现以下错误:
没有什么比像这样解析坐标位置更容易的了:
{
latitude: parseFloat(myObj.latitude),
longitude: parseFloat(myObj.longitude)
}
