我有一個位置監聽器類和一個服務類。在我的位置監聽器類中,我開始使用GPS,並且每隔10秒就會繼續獲取位置。我的要求是每晚7點停止GPS位置更新。我正嘗試使用removeupdates在服務中停止GPS更新,但它不起作用。我怎樣才能做到這一點。以下是我的代碼。如何在android中刪除服務類中的位置更新?
LocationGPS.java
public class LocationGPS extends Activity implements LocationListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
public static LocationManager locationManager;
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10*1000 , 0 ,this);
Intent myIntent = new Intent(this, PIService.class);
PendingIntent sevenPMIntent = PendingIntent.getService(this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 19);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
//alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000, sevenPMIntent);
}
@Override
public void onLocationChanged(Location location) {
Toast.makeText(getApplicationContext(), "got new location", Toast.LENGTH_SHORT).show();
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}
PIService.java
public class PIService extends Service{
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public int onStartCommand (Intent intent, int flags, int startId)
{
super.onStartCommand(intent, flags, startId);
//Get the system current time.
Date dt = new Date();
int hours = dt.getHours();
//Compare the current time with 7PM
if(hours == 19){
//if current time is 7PM
Toast.makeText(getApplicationContext(), "Now the time is 7PM", Toast.LENGTH_LONG).show();
LocationGPS.locationManager.removeUpdates(new LocationGPS()); //here is the place i am trying to remove the location updates.
}
}
return START_STICKY;
}
}
