原标题:trouble with obtaining user location via gps from htc wildfire s

我想得到用户位置,这里有Gps 这是我的代码

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        t=(TextView)findViewById(R.id.textView1);


        LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        LocationListener mlocListener = new MyLocationListener();

        mlocManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mlocListener);

    }

    public class MyLocationListener implements LocationListener
    {

        @Override
        public void onLocationChanged(Location location) {
            // TODO Auto-generated method stub
            double lat=location.getLatitude();
            double longt= location.getLongitude();


            Geocoder gc=new Geocoder(getApplicationContext(),Locale.getDefault());
               try
               {
                   List <Address> adresses=gc.getFromLocation(lat, longt, 1);
                   StringBuilder sb=new StringBuilder();
                   if(adresses.size()>0)
                   {
                       Address address=adresses.get(0);
                       for(int i=0;i<address.getMaxAddressLineIndex();i++)
                           sb.append(address.getAddressLine(i)).append("
");

                       sb.append(address.getLocality()).append("
");
                       sb.append(address.getPostalCode()).append("
");
                       sb.append(address.getCountryName());

                   }

                   String a="Latitude:"+lat+"
Longtitude:"+longt+"
Address:"+sb.toString();
                   t.setText(a);
               }

               catch(Exception e)
               {
                   t.setText("Error.
"+e.toString());
               }
        }

我给予所有许可;

2.2.3 装置是 HTC 野火 S

代码代码不会丢出错误,但它也没有作用

有人知道吗?

问题回答

你是否通过免费的应用程序或其它方式确认,你应该有一个GPS位置?有时我30分钟、60分钟、2小时都没有固定位置...即使我之前在同一地点也有一个固定位置。我现在在哪里,我从来没有得到一个固定的室内;但如果我走出去,然后进去,我会得到一个固定位置。

您的代码对我的 HTC 执行罚款( 走出门后 ) 。 虽然这不影响任何现在的情况, 我建议修改:

LocationListener mlocListener = new MyLocationListener();

至:

MyLocationListener mlocListener = new MyLocationListener();

使我的听众变得更为复杂。
