Android手机GPS问题

Question

我正在研究在Android手机（三星Galaxy GT 15801和Micromax A60）中使用GPS绘制旅行方式。但有时它给了我错误的lat＆amp; long。我在印度，但它显示我在阿拉伯海中部的某个地方，并在一段时间后显示正确的纬度和长度。帮我解决这个问题。

Answer 1

在活动中使用

LocationManager mlocManager = (LocationManager)getSystemService(this.LOCATION_SERVICE);
            LocationListener mlocListener = new GetGPS(LoginPanel.this);
     Criteria criteria = new Criteria();
                criteria.setAccuracy(Criteria.ACCURACY_FINE);
                criteria.setAltitudeRequired(false);
                criteria.setBearingRequired(false);
                criteria.setCostAllowed(true);
                criteria.setPowerRequirement(Criteria.POWER_LOW);
        String provider = mlocManager.getBestProvider(criteria, true);
             mlocManager.requestLocationUpdates(provider, 0, 0, mlocListener);

只需将其用作单独的类

    public class GetGPS implements LocationListener 
{
    GlobalVariable globalInstance;

    public GetGPS(Context context)
    {

    }
    public void onLocationChanged(Location location) 
    {

        //location.getLatitude();
            //location.getLongitude();


    }
    public void onProviderDisabled(String provider) 
    {
        //alertDialog.showMessage("Please Turn On your GPS", "GPS Turned Off");

    }
    public void onProviderEnabled(String provider) 
    {

    } 
    public void onStatusChanged(String provider, int status, Bundle extras) 
    {

    }
