Example 22 with LatLng

use of com.amap.api.maps.model.LatLng in project MVVM-Demo by lilongweidev.

the class MapFragment method switchMapCenter.

/**
 * 切换地图中心
 */
private void switchMapCenter(GeocodeResult geocodeResult, LatLonPoint latLonPoint) {
    // 显示解析后的坐标，
    double latitude = latLonPoint.getLatitude();
    double longitude = latLonPoint.getLongitude();
    // 创建经纬度对象
    LatLng latLng = new LatLng(latitude, longitude);
    // 改变地图中心点
    // 参数依次是：视角调整区域的中心点坐标、希望调整到的缩放级别、俯仰角0°~45°（垂直与地图时为0）、偏航角 0~360° (正北方为0)
    CameraUpdate mCameraUpdate = CameraUpdateFactory.newCameraPosition(new CameraPosition(latLng, 18, 30, 0));
    // 在地图上添加marker
    aMap.addMarker(new MarkerOptions().position(latLng).title(geocodeResult.getGeocodeQuery().getLocationName()).snippet("DefaultMarker"));
    // 动画移动
    aMap.animateCamera(mCameraUpdate);
    // 移动地图后通过坐标转地址，触发onRegeocodeSearched回调，在这个回调里去查询天气
    RegeocodeQuery query = new RegeocodeQuery(latLonPoint, 20, GeocodeSearch.AMAP);
