滑动地图后调用这个方法就能获取滑动后经纬度的周边信息:
/** * 滑动后的经纬度 * */ mBaiduMap.setOnMapStatusChangeListener(new BaiduMap.OnMapStatusChangeListener() { @Override public void onMapStatusChangeStart(MapStatus mapStatus) { } @Override public void onMapStatusChangeStart(MapStatus mapStatus, int i) { } @Override public void onMapStatusChange(MapStatus mapStatus) { } @Override public void onMapStatusChangeFinish(MapStatus mapStatus) { LatLng _latLng = mapStatus.target; Log.e("滑动后的经纬度", "经度:" + _latLng.longitude + "纬度:" + _latLng.latitude); setPopupTipsInfo(_latLng); } });这是全部的文件
