場所の問題、すべてのイム新へ

Question

こんにちはAndroidにと私は小さな問題を抱えていると、誰かが私に助けることができる場合、私は本当に感謝し

最初のイムは、すべての利用可能な位置プロバイダとそのが動作していないと2を表示しようとすると、これまで私私が利用可能な最善のプロバイダからの任意の位置情報を得ることはありません、それを実行し、私は多くのことを検索した後、前にも同じ問題を抱えていた事前

Answer 1

に おかげで（私は私の無線LANやネットワーク上のプロバイダを持っています）。.. .cameソリューションになり、次のコードを介してデバイスの瞬時の位置を取得する可能性があります...私たちはgps responscを持つことはできません瞬時に私たちはセルタワーや無線LANに基づいて私たちの場所を持つことができます。そう

@Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.leopard_screen); 

      FindLocation(this); 
     } 


     public void FindLocation(Context context) { 

      locationManager = (LocationManager) context 
        .getSystemService(Context.LOCATION_SERVICE); 

      gps_enabled = locationManager 
        .isProviderEnabled(LocationManager.GPS_PROVIDER); 
      network_enabled = locationManager 
        .isProviderEnabled(LocationManager.NETWORK_PROVIDER); 

      if (network_enabled) { 
       locationManager.requestLocationUpdates(
         LocationManager.NETWORK_PROVIDER, 0, 0, 
         locationListenerNetwork); 
       Log.i("@@@@@@@@@@ Network provider is enabled", "Network Provider"); 
      } else { 
       Toast.makeText(LeopardScreen.this, 
         "Network provider is not enabled", 2000); 
      } 

      if (gps_enabled) { 
       locationManager.requestLocationUpdates(
         LocationManager.GPS_PROVIDER, 0, 0, locationListenerGPS); 
       Log.i("@@@@@@@@@@ GPS provider is enabled", "GPS Provider"); 
      } else { 
       Toast.makeText(LeopardScreen.this, "GPS provider is not enabled", 
         2000); 
      } 

      if(!network_enabled && !gps_enabled) { 
       currentLocation = getMyLastKnownLocation(); 
       currentLatitude = currentLocation.getLatitude(); 
       currentLongitude = currentLocation.getLongitude(); 

       Log.i("@@@@@@@@ Both location provider disabled", 
         "getMylastKnownLocation = "+String.valueOf(currentLatitude) 
         + " : " + String.valueOf(currentLongitude)); 
       Toast.makeText(LeopardScreen.this,"LastKnownLocation\n"+String.valueOf(currentLatitude) + "\n" 
           + String.valueOf(currentLongitude), 3000).show(); 
       Intent intent = new Intent(LeopardScreen.this, mainActivity.class); 
       startActivity(intent); 
      } 

     } 

     LocationListener locationListenerNetwork = new LocationListener() { 
      public void onLocationChanged(Location location) { 
       updateLocation(location); 
       handler.removeCallbacks(runnable); 
       Log.i("@@@@@@@@ Inside FindLocation", "Inside FindLocation"); 
       Toast.makeText(
         LeopardScreen.this,"Network Location \n"+ 
         String.valueOf(currentLatitude) + "\n" 
           + String.valueOf(currentLongitude), 5000).show(); 

      } 

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

      } 

      public void onProviderEnabled(String provider) { 
      } 

      public void onProviderDisabled(String provider) { 
      } 

     }; 

     LocationListener locationListenerGPS = new LocationListener() { 

      @Override 
      public void onLocationChanged(Location location) { 
       updateLocation(location); 

       Log.i("@@@@@@@@@@ Inside onLocationChangedGPS", String 
         .valueOf(currentLatitude) 
         + " : " + String.valueOf(currentLongitude)); 

       Toast.makeText(
         LeopardScreen.this, 
         "GPS Location \n" + String.valueOf(currentLatitude) + "\n" 
           + String.valueOf(currentLongitude), 5000).show(); 

      } 

      @Override 
      public void onStatusChanged(String provider, int status, Bundle extras) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onProviderEnabled(String provider) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onProviderDisabled(String provider) { 
       // TODO Auto-generated method stub 

      } 

     }; 

     public Location getMyLastKnownLocation() { 


       Location locNetwrok = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 
       Location locGPS = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); 
       if(locNetwrok != null) 
        return locNetwrok; 
       else if(locGPS != null) 
        return locGPS; 

       return null; 
     } 

     void updateLocation(Location location) { 
      currentLocation = location; 
      currentLatitude = currentLocation.getLatitude(); 
      currentLongitude = currentLocation.getLongitude(); 

      Log.i("@@@@@@@@ Inside LeopardScreen locationChanged", 
        "locationChanged"); 

     } 

は場所を取得するには、クラスを以下のMenifeast

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

Answer 2

使用に追加するのを忘れないでください...あなたのデバイスの瞬時位置を得るためにそれらのいずれかを可能にします。

package com.example.location; 

import android.app.AlertDialog; 
import android.app.Service; 
import android.content.Context; 
import android.content.DialogInterface; 
import android.content.Intent; 
import android.location.Location; 
import android.location.LocationListener; 
import android.location.LocationManager; 
import android.os.Bundle; 
import android.os.IBinder; 
import android.provider.Settings; 

public class GPSTracker extends Service implements LocationListener{ 

private Context context; 
boolean isGPSEnabled = false; 
boolean isNetworkEnabled = false; 
boolean canGetLocation = false; 

Location location; 
double latitude,longitude; 

LocationManager locationManager; 
AlertDialogManager am = new AlertDialogManager(); 
public GPSTracker(Context context){ 
    this.context = context; 
    getLocation(); 
} 
private Location getLocation() { 
    // TODO Auto-generated method stub 
    try{ 
     locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); 

     isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); 

     isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); 


     if (!isGPSEnabled && !isNetworkEnabled){ 

     } else { 
      this.canGetLocation = true; 

      if (isNetworkEnabled){ 

       locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 60000, 3, this); 

       if (locationManager != null){ 
        location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 
        if (location != null){ 
         latitude = location.getLatitude(); 
         longitude = location.getLongitude(); 
        } 
       } 
      } 

      if (isGPSEnabled){ 
       if (location == null){ 
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000, 3, this); 
        if (locationManager != null){ 
         location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); 
         if (location != null){ 
          latitude = location.getLatitude(); 
          longitude = location.getLongitude(); 
         } 
        } 
       } 
      } else { 
       showAlertDialog(); 
      } 
     } 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 
    return location; 
} 


public void showAlertDialog(){ 
    am.showAlertDialog(GPSTracker.this, "GPS Setting", "Gps is not enabled. Do you want to enabled it ?", false); 
} 
public double getLatitude(){ 
    if (location != null){ 
     latitude = location.getLatitude(); 
    } 

    return latitude; 
} 

public double getLongitude(){ 
    if (location != null){ 
     longitude = location.getLongitude(); 
    } 

    return longitude; 
} 

public boolean canGetLocation(){ 
    return this.canGetLocation; 
} 
@Override 
public void onLocationChanged(Location location) { 
    // TODO Auto-generated method stub 
    if (location != null){ 
     this.location = location; 
    } 
} 

@Override 
public void onProviderDisabled(String provider) { 
    // TODO Auto-generated method stub 

} 

@Override 
public void onProviderEnabled(String provider) { 
    // TODO Auto-generated method stub 

} 

@Override 
public void onStatusChanged(String provider, int status, Bundle extras) { 
    // TODO Auto-generated method stub 

} 

@Override 
public IBinder onBind(Intent intent) { 
    // TODO Auto-generated method stub 
    return null; 
} 

} 

このクラスのオブジェクトを以下のように主に作成します。

GPSTracker gps = new GPSTracker(); 
double latitude = gps.getLatitude(); 
double longitude = gps.getLongitude(); 

いいえManifestの許可を忘れる。

<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" /> 
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
