Question

I am using LocationListener on my application. However, whenever my location changes or onLocationChanged(Location location) method is executed, the coordinates of my location does not change at all. I am riding inside a car and had traveled several meters to kilometers already without my location changing. What could be the problem?

我的法典:

LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
String bestProvider = locationManager.getBestProvider(new Criteria(), true);
{LocationListener locationListener = new LocationListener()
{
    public void onLocationChanged(Location location)
    {
        //location.getLatitude(), location.getLongtitude()
        //location coordinates does not change at all everytime onLocationChanged is called even after I already move several meters or kilometers.
    }

    //...
}
locationManager.requestLocationUpdates(bestProvider, 0, 0, locationListener);

Answer 1

引言

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, 
        locationListener);

你们可能利用网络提供者。听众通常被解职。你们可以安排听众参加活动。

不能确定由甲体确定最佳提供者的逻辑是什么。但是,与网络供应商相比,全球定位系统总是被认为是最准确的。但是,在通过全球定位系统锁定一个位置时,有些条件是不可能的。当网络提供者投入使用时。

我通常创设一个简单类别,要求获得地点编码。在职能方面,我首先要求使用全球定位系统的地点。如果没有收到,则我等待30秒,然后请它使用网络供应商。这样,我就能够永远确保我获得全球定位系统的价值,作为我的第一选择。

我的猜测是,你的位置正在发生变化,但你却忽视了自由度和长足的精髓。注:在地点变更之前和之后精度部分的最后数。

Answer 3

以这种方式对待你的法典

if(isInternetEnabled==true)//check for internet connection here
{
 locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,  
        locationListener);  
}
else
{
 locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,  
        locationListener);  
}

Because it happens with me that GPS_PROVIDER doesn t give quick response to location update then NETWORK_PROVIDER.
