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,
    }));
  }

onDragEnd = {(e)=> {console.log('dragEnd',e.nativeEvent.coordinate)}}

onDragEnd返回{ coordinate: LatLng, position: Point },请查看marker doc
