• 【MUI】百度地图定位功能


    博主最近进行一款APP开发,需要用到定位功能,经过一番折腾,终于搞定,不废话,代码如下

    mui.plusReady(function() {
    
                    var longitude, latitude;
                    //var map = new BMap.Map("container");
    
    //                navigator.geolocation.getCurrentPosition(function(position) {
    //                    longitude = position.coords.longitude;
    //                    latitude = position.coords.latitude;
    //
    //                    console.log("longitude:" + longitude + "==latitude:" + latitude);
    //                    var point = new BMap.Point(longitude, latitude);
    //                    map.centerAndZoom(point, 20); // 初始化地图,设置中心点坐标和地图级别  
    //                    var marker = new BMap.Marker(point); // 创建标注
    //                    map.addOverlay(marker); // 将标注添加到地图中
    //                    map.panTo(point);
    //                });
    
                    plus.geolocation.getCurrentPosition(translatePoint, function(e) {
                        mui.toast("异常:" + e.message);
                    });
    
                    function translatePoint(position) {
                        var currentLon = position.coords.longitude;
                        var currentLat = position.coords.latitude;
                        var gpsPoint = new BMap.Point(currentLon, currentLat);
                        BMap.Convertor.translate(gpsPoint, 2, initMap); //坐标转换
                    }
    
                    function initMap(point) {
                        map = new BMap.Map("container"); //创建地图
                        map.addControl(new BMap.NavigationControl());
                        map.addControl(new BMap.ScaleControl());
                        map.addControl(new BMap.OverviewMapControl());
                        map.centerAndZoom(point, 15);
                        map.addOverlay(new BMap.Marker(point));
    
                    }
    
                    //                setTimeout(function() {
                    //                    var gpsPoint = new BMap.Point(longitude, latitude);
                    //                    BMap.Convertor.translate(gpsPoint, 0, function(point) {
                    //                        var geoc = new BMap.Geocoder();
                    //                        geoc.getLocation(point, function(rs) {
                    //                            var addComp = rs.addressComponents;
                    //                            mui.alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber);
                    //                        });
                    //                    });
                    //                }, 3000);
    
                });

    注意,在使用过程中,需要引入百度地图的JS

    <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=开发者key"></script>
            <script type="text/javascript" src="http://developer.baidu.com/map/jsdemo/demo/convertor.js"></script>

    其中,开发者key需要自己去百度地图开发者平台申请,此处教程上链接http://lbsyun.baidu.com/index.php?title=androidsdk/guide/key
