重複獲取地理位置（每隔1分鐘後）

Question

我打電話給AndroidGPSTrackingActivity.class敬酒信息。如何獲取每隔1分鐘後緣位置。有了下面的代碼，我在清單隻得到一次

public class AndroidGPSTrackingActivity extends Activity { 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 



gps = new GPSTracker(AndroidGPSTrackingActivity.this); 
    // check if GPS enabled 
    if (gps.canGetLocation()) { 

double  latitude = gps.getLatitude(); 
double longitude = gps.getLongitude(); 
       Toast.makeText(getApplicationContext(),"Your Locion is - \nLat: " + latitude 
      + "\nLog: " + longitude, Toast.LENGTH_LONG).show(); 

       System.out.println("respmaillati::;;"+latitude); 



    } else { 

     gps.showSettingsAlert(); 
    } 


} 

我給

<service android:name=".GPSTracker" /> 

代碼：

public class GPSTracker extends Service implements LocationListener { 

private final Context mContext; 

// flag for GPS status 
boolean isGPSEnabled = false; 

// flag for network status 
boolean isNetworkEnabled = false; 

// flag for GPS status 
boolean canGetLocation = false; 

Location location; // location 
double latitude; // latitude 
double longitude; // longitude 

// The minimum distance to change Updates in meters 
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters 

// The minimum time between updates in milliseconds 
private static final long MIN_TIME_BW_UPDATES = 100 * 60 * 1; // 1 minute 

// Declaring a Location Manager 
protected LocationManager locationManager; 

public GPSTracker(Context context) { 
    this.mContext = context; 
    getLocation(); 
} 

public Location getLocation() { 
    try { 
     locationManager = (LocationManager) mContext 
       .getSystemService(LOCATION_SERVICE); 

     // getting GPS status 
     isGPSEnabled = locationManager 
       .isProviderEnabled(LocationManager.GPS_PROVIDER); 

     // getting network status 
     isNetworkEnabled = locationManager 
       .isProviderEnabled(LocationManager.NETWORK_PROVIDER); 

     if (!isGPSEnabled && !isNetworkEnabled) { 
      // no network provider is enabled 
     } else { 
      this.canGetLocation = true; 
      // First get location from Network Provider 
      if (isNetworkEnabled) { 
       locationManager.requestLocationUpdates(
         LocationManager.NETWORK_PROVIDER, 
         MIN_TIME_BW_UPDATES, 
         MIN_DISTANCE_CHANGE_FOR_UPDATES, this); 
       Log.d("Network", "Network"); 
       if (locationManager != null) { 
        location = locationManager 
          .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 
        if (location != null) { 
         latitude = location.getLatitude(); 
         longitude = location.getLongitude(); 
        } 
       } 
      } 
      // if GPS Enabled get lat/long using GPS Services 
      if (isGPSEnabled) { 
       if (location == null) { 
        locationManager.requestLocationUpdates(
          LocationManager.GPS_PROVIDER, 
          MIN_TIME_BW_UPDATES, 
          MIN_DISTANCE_CHANGE_FOR_UPDATES, this); 
        Log.d("GPS Enabled", "GPS Enabled"); 
        if (locationManager != null) { 
         location = locationManager 
           .getLastKnownLocation(LocationManager.GPS_PROVIDER); 
         if (location != null) { 
          latitude = location.getLatitude(); 
          longitude = location.getLongitude(); 
         } 
        } 
       } 
      } 
     } 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

    return location; 
} 

/**

Answer 1

使用google Fusion api example爲GET間隔的位置。

Answer 2

試試這個！ 包裹敬酒代碼方法，並利用處理器和Runnable的遞歸調用它：

public class AndroidGPSTrackingActivity extends Activity { 

Handler showLocationHandler; 
Runnable showLocationRunnable; 
private static final int DELAY_TIME = 1000 * 60; //delay time - 1 minute 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 


    gps = new GPSTracker(AndroidGPSTrackingActivity.this); 
    showLocationHandler = new Handler(); 
    showLocationRunnable = new Runnable() { 
     @Override 
     public void run() { 
      showLatLongToast(); 
     } 
    }; 

    //call the method once 
    showLatLongToast(); 
} 

public void showLatLongToast() { 
    if (gps.canGetLocation()) { 

     double latitude = gps.getLatitude(); 
     double longitude = gps.getLongitude(); 
     Toast.makeText(getApplicationContext(), "Your Locion is - \nLat: " + latitude 
       + "\nLog: " + longitude, Toast.LENGTH_LONG).show(); 

     System.out.println("respmaillati::;;" + latitude); 


    } else { 

     gps.showSettingsAlert(); 
    } 
    //call the same method after some delay 
    showLocationHandler.postDelayed(showLocationRunnable, DELAY_TIME); 
} 

@Override 
protected void onDestroy() { 
    super.onDestroy(); 
    //kill this runnable when ever you want to stop displaying toast like this 
    showLocationHandler.removeCallbacks(showLocationRunnable); 
    } 
}
