使用 Phonegap 和 Android 的地理位置答案

【问题标题】：GeoLocation using Phonegap and Android使用 Phonegap 和 Android 的地理位置

【问题描述】：

我正在 phonegap 上设计一个移动应用程序。在这我试图获得用户的当前位置。但我没有在 Andriod Emulator 上获得地图。我使用了这段代码：

<!DOCTYPE HTML>

<html>

     <head>

<meta name="viewport" content="width=device-width; height=device-height; user-scalable=no" />

<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<title>PhoneGap Map</title>
<link rel="stylesheet" href="/master.css" type="text/css" media="screen" />
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>
<script type="text/javascript">

function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}

function onDeviceReady() {
    navigator.geolocation.getCurrentPosition(onSuccess, onError,{alert("error"),"enableHighAccuracy":true,"timeout":3000});

}

//GEOLOCATION
var onSuccess = function(position) {
    alert("Latitude: "  + position.coords.latitude   + "\n" +
          "Longitude:" + position.coords.longitude  + "\n");

    var myLat = position.coords.latitude;
    var myLong = position.coords.longitude;

    //MAP
    var mapOptions = {
        center: new google.maps.LatLng(myLat, myLong),
        zoom: 14,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };

    var map = new google.maps.Map(document.getElementById("map_canvas"),
                                  mapOptions);

};

// onError Callback receives a PositionError object
//
function onError(error) {
    alert("code: "    + error.code    + "\n" +
          "message: " + error.message + "\n");
}


     </script>

     </head>
     <body onload="onLoad()"> 
     <div>map</div>
     <div id="map_canvas" style="width:100px; height: 100px;" ></div>
     </body>
     </html>

我不知道我错在哪里。有人可以帮我解决这个问题吗？

【问题讨论】：

你的代码执行了吗？您是否收到任何警报，无论是成功还是错误？
没有大卫，我得到的只是空白页
尝试将navigator.geolocation.getCurrentPosition(onSuccess, onError,{alert("error"),"enableHighAccuracy":true,"timeout":3000}); 放入onLoad 函数中
Davids- 我试过了，但结果一样。我有一个疑问，当我在 PC 浏览器中运行时，我得到了 Geolocation。AVD 有什么问题>
您是否将 maps.googleapis.com 域列入白名单？

【解决方案1】：

检查此代码...将cordova-1.8.1.js 更改为您的cordova2.0.js...其余源代码请在线参考。如果它不起作用。那么你的phonegap配置有问题。

【讨论】：

我没有在你的代码中工作。因为不清楚您是否正确设置了phonegap的环境。所以试试这个。如果它不工作。然后你再次完成整个设置。
RED.Skull- 谢谢，但这是为了通过静态提供 latlng 来获取地图。我得到了它。但我正在尝试当前用户位置，但我没有在 AVD 上得到它。
你能提供你的 logcat 错误信息吗？另一件事是在设备上试试
