Android 钛合金中的地理定位为空

发布于 2024-11-06 09:24:59 字数 1330 浏览 1 评论 0原文

我无法在模拟器或实体手机上获取地理位置。

我正在使用 Titanium SDK 1.6.2、ADK 2.2。

我遵循了此处使用的方法 无济于事。

我缺少什么？提前致谢。

错误：

执行此分配时，表示 e.coords 为 null。 f_lng = e.coords.longitude;

代码：

function get_geolocation() {

    try {

        Ti.Geolocation.preferredProvider = 'gps';
        Titanium.Geolocation.accuracy = Titanium.Geolocation.ACCURACY_BEST;
        Titanium.Geolocation.distanceFilter = 10;

        if( Titanium.Geolocation.locationServicesEnabled === false ) {
            throw('Your device has GPS turned off. Please turn it on.');
        }

        var f_lat, f_lng;

        Titanium.Geolocation.getCurrentPosition(function(e) {

            if( ! e.success || e.error ) {
                alert("Unable to get your location.");
            }

            f_lng = e.coords.longitude;
            f_lat = e.coords.latitude;
        });

        return {
            's_status': 'success',
            'f_lat': f_lat,
            'f_lng': f_lng
        };

    } catch( s_error ) {

        return {
            's_status': 'error',
            's_message': s_error
        };
    }
}

I can't get geolocations in the emulator or on a physical phone.

I'm using Titanium SDK 1.6.2, ADK 2.2.

I've followed the approaches used here to no avail.

What am I missing? Thanks in advance.

Error:

Says that e.coords is null when doing this assignment. f_lng = e.coords.longitude;

Code:

function get_geolocation() {

    try {

        Ti.Geolocation.preferredProvider = 'gps';
        Titanium.Geolocation.accuracy = Titanium.Geolocation.ACCURACY_BEST;
        Titanium.Geolocation.distanceFilter = 10;

        if( Titanium.Geolocation.locationServicesEnabled === false ) {
            throw('Your device has GPS turned off. Please turn it on.');
        }

        var f_lat, f_lng;

        Titanium.Geolocation.getCurrentPosition(function(e) {

            if( ! e.success || e.error ) {
                alert("Unable to get your location.");
            }

            f_lng = e.coords.longitude;
            f_lat = e.coords.latitude;
        });

        return {
            's_status': 'success',
            'f_lat': f_lat,
            'f_lng': f_lng
        };

    } catch( s_error ) {

        return {
            's_status': 'error',
            's_message': s_error
        };

顺着亚伦的回答，这是对我来说在 iPhone 模拟器、iPhone 和 Android 手机（不是 Android 模拟器）上有用的方法。请记住，我使用 redux 因此代码会略有不同。

var path = Ti.Platform.name == 'android' ? Ti.Filesystem.resourcesDirectory : "../../";

var map = {

    top: 0,
    bottom: 0,
    latitude: 0,
    longitude: 0,
    latitudeDelta: 0.1,
    longitudeDelta: 0.1,
    display: "map",

    init: function (annotations, latitude, longitude, top, bottom, delta) {

        if (top)
            map.top = top;
        if (bottom)
            map.bottom = bottom;
        if (delta) {
            map.latitudeDelta = delta;
            map.longitudeDelta = delta;
        }

        map.createMap(annotations, latitude, longitude);
        map.createOptions();
        map.getLocation();

    },

    createMap: function (annotations, latitude, longitude) {

        map.mapView = Ti.Map.createView({
            mapType: Ti.Map.STANDARD_TYPE, animate: true, regionFit: false, userLocation: true,
            region: { latitude: latitude, longitude: longitude, latitudeDelta: map.latitudeDelta, longitudeDelta: map.longitudeDelta },
            annotations: annotations, bottom: map.bottom, top: map.top, borderWidth: 1
        });
        if (!isAndroid) {
            map.mapView.addAnnotation(annotations[0]);
        }
        map.mapView.selectAnnotation(annotations[0]);
        win.add(map.mapView);

    },

    createOptions: function () {

        //map/satellite displays.
        var mapDisplay = new ImageView({ image: path + 'images/map/satellite-view.png', width: 70, height: 49, zIndex: 2, top: map.top + 5, right: 5 });
        mapDisplay.addEventListener('click', function () {

Piggy-backing off of Aaron's answer, here is what worked for me on IPhone Simulator, IPhone, and Android phone (not Android simulator). Keep in mind that I use redux so the code will be a little different.

var path = Ti.Platform.name == 'android' ? Ti.Filesystem.resourcesDirectory : "../../";

var map = {

    top: 0,
    bottom: 0,
    latitude: 0,
    longitude: 0,
    latitudeDelta: 0.1,
    longitudeDelta: 0.1,
    display: "map",

    init: function (annotations, latitude, longitude, top, bottom, delta) {

        if (top)
            map.top = top;
        if (bottom)
            map.bottom = bottom;
        if (delta) {
            map.latitudeDelta = delta;
            map.longitudeDelta = delta;
        }

        map.createMap(annotations, latitude, longitude);
        map.createOptions();
        map.getLocation();

    },

    createMap: function (annotations, latitude, longitude) {

        map.mapView = Ti.Map.createView({
            mapType: Ti.Map.STANDARD_TYPE, animate: true, regionFit: false, userLocation: true,
            region: { latitude: latitude, longitude: longitude, latitudeDelta: map.latitudeDelta, longitudeDelta: map.longitudeDelta },
            annotations: annotations, bottom: map.bottom, top: map.top, borderWidth: 1
        });
        if (!isAndroid) {
            map.mapView.addAnnotation(annotations[0]);
        }
        map.mapView.selectAnnotation(annotations[0]);
        win.add(map.mapView);

    },

    createOptions: function () {

        //map/satellite displays.
        var mapDisplay = new ImageView({ image: path + 'images/map/satellite-view.png', width: 70, height: 49, zIndex: 2, top: map.top + 5, right: 5 });
        mapDisplay.addEventListener('click', function () {

                map.display = "map";
            }
        });
        win.add(mapDisplay);

您是否尝试过设置超时以确保在使用之前设置e.coords，有人建议将其作为临时修复？

setTimeout(function() {
    return e.coords
}, 1000);

Have you tried setting a timeout to make sure the e.coords is set before you use it, it has been suggested as a temporary fix?

setTimeout(function() {
    return e.coords
}, 1000);
