現在、Androidでのアクティビティで使用するための以下のコーディングがあります。今、私はこれをオブジェクトとして使用し、場所のスキャンを開始し、3秒後にハンドラーを使用してreturnBestLocationメソッドを使用してその場所を取得します。
ただし、MyLocationListenerオブジェクトが、3秒後にオブジェクトを元の場所に呼び出すのではなく、場所の変更時にアクティビティの呼び出しを自動的に返す可能性はありますか？
public class MyLocationListener implements LocationListener {
LocationManager locationManager;
Date currentBestLocationDate;
Intent notificationIntent;
Context mContext;
Location currentBestLocation = null, lastKnownLocation=null;
public MyLocationListener(Context mContext)
{this.mContext = mContext;
}
public void startLocationScan()
{
Log.d(Config.log_id, "Custom Location Listener started");
if (locationManager == null) {
locationManager = (LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE);
Location locationNETWORK = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (locationNETWORK != null) {
lastKnownLocation=locationNETWORK;
}
Location locationGPS = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (locationGPS != null) {
lastKnownLocation=locationGPS;
}
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, MyLocationListener.this);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,MyLocationListener.this);
}
}
public void stopLocationScan()
{
if(locationManager!=null)
{
locationManager.removeUpdates(MyLocationListener.this);
Log.d(Config.log_id, "Custom Location Listener Stopped");
}
}
public Location returnBestLocation()
{
return currentBestLocation;
}
