我刚开始使用react native maps〜0.22.1,但是在获取可拖动标记onDragend新位置时遇到问题; 我遵循了文档,即使它有点流浪,但结果是不确定的;
这是我的代码:
<Marker
ref={(ref) => { this.marker = ref; }}
draggable
onDragEnd={(t, map, coords) => this.setDestination(coords)}
coordinate={destination}
position={destination}
centerOffset={{ x: -18, y: -60 }}
anchor={{ x: 0.69, y: 1 }}
pinColor={COLOR.marker}
onDragStart={() => this.setMarkerPosition()}
/>
setDestination函数:
setDestination(coords) {
const { destination } = this.props;
const lat = coords.lat();
const long = coords.lng();
console.log('seperate:', lat, long);
console.log('destina:', coords);
this.props
.dispatch($setDestination(coords.lat(), coords.lng()))
.catch((error) => this.props.dispatch(Activity.$toast('failure', error.message)));
this.setState((prevState) => ({
isVisible: !prevState.isVisible,
destination: destination[0].fullAddress,
}));
}
答案 0 :(得分:0)
onDragEnd = {(e)=> {console.log('dragEnd',e.nativeEvent.coordinate)}}
答案 1 :(得分:-1)
onDragEnd
返回{ coordinate: LatLng, position: Point }
,请查看marker doc
