I am trying to add a google map to my android tablet to detect where the terminal is.But the map is not displayed completely. only a small part was displayed. and after rotate the screen, it can displayed perfectly.
I did all this according to http://www.digitalnoiz.com/mobile-development/geolocation-jquery-mobile-maps/
This is my html code:

This is my Jquery code, all my function code are edited in application.js.
function onLoad() {
console.log('Init reached');
$.mobile.allowCrossDomainPages = true;
$.mobile.showPageLoadingMsg();
$.support.cors = true;
document.addEventListener('deviceready', onDeviceReady, false);
}
function onDeviceReady() {
console.log('Starting up...');
// navigator.app.overrideBackbutton(true);
document.addEventListener("backbutton", onBackKeyDown, false);
console.log('Initializing db');
refreshpage();
getPosition();
}
function getPosition(){
var geoOptions = { enableHighAccuracy: true, timeout: 10000 };
navigator.geolocation.getCurrentPosition(function(position){ // geoSuccess
// we have the position
var geolocation = $('#geolocation');
geolocation.html('<table></table>');
var table = geolocation.find('table');
if(position.coords.latitude)
table.append('<tr><th>Latitude</th><td>' + position.coords.latitude + '</td></tr>');
if(position.coords.longitude)
table.append('<tr><th>Longitude</th><td>' + position.coords.longitude + '</td></tr>');
if(position.coords.altitude)
table.append('<tr><th>Altitude</th><td>' + position.coords.altitude + '</td></tr>');
if(position.coords.accuracy)
table.append('<tr><th>Accuracy</th><td>' + position.coords.accuracy + '</td></tr>');
if(position.coords.altitudeAccuracy)
table.append('<tr><th>Altitude Accuracy</th><td>' + position.coords.altitudeAccuracy + '</td></tr>');
if(position.coords.heading)
table.append('<tr><th>Heading</th><td>' + position.coords.heading + '</td></tr>');
if(position.coords.speed)
table.append('<tr><th>Speed</th><td>' + position.coords.speed + '</td></tr>');
if(position.coords.timestamp)
table.append('<tr><th>Timestamp</th><td>' + new Date(position.timestamp) + '</td></tr>');
//show position on map
var map_canvas = $('#map_canvas');
map_canvas.gmap(
{'center' : position.coords.latitude + ',' + position.coords.longitude,
'zoom' : 12,
'disableDefaultUI':true,
'callback':function(){
var self = this;
var marker = self.addMarker({ 'position' : this.get('map').getCenter() });
marker.click(function(){
self.openInfoWindow({ 'content' : 'This is your current location' }, this);
});
}
});
}, function(error){ // geoError
navigator.notification.alert('error: ' + error.message + '\n' + 'code: ' + error.code);
}, geoOptions);
}
Can anybody could give me some advices?
I had this too (especially in Chrome on the desktop) and solved it by resizing the map when it had finished rendering (in ‘idle’ state):
