我正在使用服务类,它调用了我的内部类实现的位置监听器,以提供我的位置详细信息...但我需要定期执行此操作。我已经使用了带有循环器的线程,但它只执行一次,请帮助。

public class MyService extends Service
{
String GPS_FILTER = "";
Thread triggerService;
LocationListener locationListener;
LocationManager lm;
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1000; // in Meters
private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000*60; // in Milliseconds
protected LocationManager locationManager;
boolean isRunning = true;
@Override
public void onCreate()
{
// TODO Auto-generated method stub
super.onCreate();
GPS_FILTER = "MyGPSLocation";
// locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// locationManager.requestLocationUpdates(
// LocationManager.GPS_PROVIDER,
// MINIMUM_TIME_BETWEEN_UPDATES,
// MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
// new MyLocationListener());
}
@Override
public void onStart(Intent intent, int startId)
{
// TODO Auto-generated method stub
super.onStart(intent, startId);
turnGPSOn();
Toast.makeText(getApplicationContext(), "Hello1",Toast.LENGTH_LONG).show();
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationListener = new MyLocationListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,MINIMUM_TIME_BETWEEN_UPDATES, 1.0f, locationListener);
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
// removeGpsListener();
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
// private void removeGpsListener(){
// try{
// lm.removeUpdates(locationManager);
// }
// catch(Exception ex){
// System.out.println("Exception in GPSService --- "+ex);
// }
// }
private class MyLocationListener implements LocationListener
{
public void onLocationChanged(Location location)
{
postdata(location.getLatitude(),location.getLongitude());
String message = String.format(
"New Location \n Longitude: %1$s \n Latitude: %2$s",
location.getLongitude(), location.getLatitude()
);
Toast.makeText(MyService.this, message, Toast.LENGTH_LONG).show();
turnGPSOnOff();
}
public void onStatusChanged(String s, int i, Bundle b) {
// Toast.makeText(MyService.this, "Provider status changed",
// Toast.LENGTH_LONG).show();
}
public void onProviderDisabled(String s) {
// Toast.makeText(MyService.this,
// "Provider disabled by the user. GPS turned off",
// Toast.LENGTH_LONG).show();
}
public void onProviderEnabled(String s) {
// Toast.makeText(MyService.this,
// "Provider enabled by the user. GPS turned on",
// Toast.LENGTH_LONG).show();
}
}
也可以使用以下方式调用服务:
Calendar cur_cal = Calendar.getInstance();
cur_cal.setTimeInMillis(System.currentTimeMillis());
Intent intent = new Intent(this, MyService.class);
PendingIntent pintent = PendingIntent.getService(login.this, 0, intent, 0);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cur_cal.getTimeInMillis(), 60*1000, pintent);
