在获得GPS问题的Andr​​oid 2.1（找到答案）坐标 [英] problem in getting gps coordinates in android 2.1(Found Answer)

问题描述

我有在获得2.1的GPS坐标的一个问题。

在code我使用的，现在在1.6工作良好，但是当我测试
1.6设备同样的apk是显示空值

请帮我找到一种方法一起工作2.1设备也

下面是我的code。

 公共类GpsLocator {   私人静态字符串提供程序=GPS;
   私人的LocationManager myLocationManager = NULL;   公共GpsLocator（上下文的背景下）{
      myLocationManager =（的LocationManager）context.getSystemService（Context.LOCATION_SERVICE）;
   }   公共无效myOnresume（）{
      myLocationManager.requestLocationUpdates（PROVIDER，0，0，onLocationChange）;
   }   公共无效myonPause（）{
       myLocationManager.removeUpdates（onLocationChange）;
   }   公共双getLatitude（）{
      位置LOC = myLocationManager.getLastKnownLocation（供应商）;
      如果（LOC == NULL）{
         返回（0）;
      }
      返回（loc.getLatitude（））;
   }   公共双getLongitude（）{
      位置LOC = myLocationManager.getLastKnownLocation（供应商）;
      如果（LOC == NULL）{
         返回（0）;
      }      返回（loc.getLongitude（））;
   }   LocationListener的onLocationChange =新LocationListener的（）{      公共无效onLocationChanged（地点）{
      }      公共无效onProviderDisabled（字符串提供商）{
         //所需的接口，而不是使用
      }      公共无效onProviderEnabled（字符串提供商）{
         //所需的接口，而不是使用
      }      公共无效onStatusChanged（字符串提供商，INT地位，捆绑演员）{
         //所需的接口，而不是使用
      }
   };
}
 

在manifest文件中我添加权限访问文件它们是

 ＆LT;使用许可权的android：NAME =android.permission.INTERNET对/＆GT;
＆LT;使用许可权的android：NAME =android.permission.ACCESS_COARSE_LOCATION/＆GT;
＆LT;使用许可权的android：NAME =android.permission.ACCESS_FINE_LOCATION/＆GT;
 

解决方案

 的LocationManager的LocationManager;
    字符串语境= Context.LOCATION_SERVICE;
    的LocationManager =（的LocationManager）getSystemService（背景）;
    标准标准=新标准（）;
    criteria.setAccuracy（Criteria.ACCURACY_FINE）;
    criteria.setAltitudeRequired（假）;
    criteria.setBearingRequired（假）;
    criteria.setCostAllowed（真）;
    criteria.setPowerRequirement（Criteria.POWER_LOW）;
    字符串提供商= locationManager.getBestProvider（标准，真正的）;    地点= locationManager.getLastKnownLocation（供应商）;    updateWithNewLocation（位置）;    locationManager.requestLocationUpdates（供应商，2000年，10，
                                           LocationListener的）;
  }  私人最终LocationListener的LocationListener的=新LocationListener的（）{
    公共无效onLocationChanged（地点）{
      updateWithNewLocation（位置）;
    }    公共无效onProviderDisabled（字符串提供商）{
      updateWithNewLocation（NULL）;
    }    公共无效onProviderEnabled（字符串提供商）{}
    公共无效onStatusChanged（字符串提供商，INT状态，
                                捆绑演员）{}
  };
 

I am having a problem in getting GPS coordinates in 2.1.

The code i am using right now is working well in 1.6 but when i test this same apk in 1.6 device is showing null values

please help me to find a way to work with 2.1 devices also

Here is my code.

public class GpsLocator {

   private static String PROVIDER="gps";
   private LocationManager myLocationManager=null;

   public GpsLocator(Context context) {
      myLocationManager=(LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
   }

   public void myOnresume() {
      myLocationManager.requestLocationUpdates(PROVIDER, 0,   0, onLocationChange);
   }

   public void myonPause() {
       myLocationManager.removeUpdates(onLocationChange);
   }

   public double getLatitude() {
      Location loc=myLocationManager.getLastKnownLocation(PROVIDER);
      if (loc==null) {
         return(0);
      }
      return(loc.getLatitude());
   }

   public double getLongitude() {
      Location loc=myLocationManager.getLastKnownLocation(PROVIDER);
      if (loc==null) {
         return(0);
      }

      return(loc.getLongitude());
   }

   LocationListener onLocationChange=new LocationListener() {

      public void onLocationChanged(Location location) {
      }

      public void onProviderDisabled(String provider) {
         // required for interface, not used
      }

      public void onProviderEnabled(String provider) {
         // required for interface, not used
      }

      public void onStatusChanged(String provider, int status,Bundle extras) {
         // required for interface, not used
      }
   };
}

in the manifest file i add permission for accessing file they are

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

解决方案

    LocationManager locationManager;
    String context = Context.LOCATION_SERVICE;
    locationManager = (LocationManager)getSystemService(context);
    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 = locationManager.getBestProvider(criteria, true);

    Location location = locationManager.getLastKnownLocation(provider);

    updateWithNewLocation(location);

    locationManager.requestLocationUpdates(provider, 2000, 10,   
                                           locationListener);
  }

  private final LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      updateWithNewLocation(location);
    }

    public void onProviderDisabled(String provider){
      updateWithNewLocation(null);
    }

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