现在我已经看到了一些与此相关的主题，其中大部分是因为宽度高度，但是我的代码中有这个。

<!DOCTYPE html>

    // Wait for PhoneGap to load

    document.addEventListener("deviceready", onDeviceReady, false);

    var watchID = null;

    // PhoneGap is ready
    //
    function onDeviceReady() {
        // Update every 3 seconds
        var options = { frequency: 3000, enableHighAccuracy: true };
        watchID = navigator.geolocation.watchPosition(onSuccess, onError, options);
    }



    // onSuccess Geolocation
    //
    function onSuccess(position) {
            var element = document.getElementById('geolocation');
            element.innerHTML = 'Latitude: '  + position.coords.latitude      + '<br />' +

                            '<hr />'      + element.innerHTML;

            var latLng   =  new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
            var mapOptions = {
                    center: latLng,

                    mapTypeId: google.maps.MapTypeId.ROADMAP
             };
             var map = new google.maps.Map(document.getElementById('map_holder'),mapOptions);
             var marker = new google.maps.Marker({
                    position: latLng,
                    map: map
             });
    }                            


    // onError Callback receives a PositionError object
    //
    function onError(error) { 
        var errString = '';
        // Check to see if we have received an error code
        if(error.code) {
            // If we have, handle it by case
            switch(error.code)  {
                case 1: // PERMISSION_DENIED
                errString =

                'because the device does not have permission '+
                'to the use that service.';
                break;
                case 2: // POSITION_UNAVAILABLE
                errString =
                'Unable to obtain the location information ' +
                'because the device location could not be ' +
                'determined.';
                break;
                case 3: // TIMEOUT
                errString =

                'specified time allocation.';

                default: // UNKOWN_ERROR
                errString =
                'Unable to obtain the location of the ' +
                'device due to an unknown error.';
                break;
            }
        }
        // Handle any errors we may face
        var element = document.getElementById('map_holder');
        element.innerHTML = errString;
    }

    </script>
  </head>
  <body>
    <p id="geolocation">Watching geolocation...</p>
    <button id="btnWatchPosition" onclick="onDeviceReady();">TOGGLE</button> <br>
    <div id="map_holder" width="100%" height="100%"></div>
  </body>
</html>

在我按下切换按钮后，坐标显示出来了......但没有地图显示出来，我做错了什么。

删除此行，它将在 Android Simulator (eclipse) 中运行
