Android解决GPS定位时LocationManager只能绑定一个LocationListener的问题

之前做项目时遇到了如题的小困难, 想了一个有点解决方法, 上周在济南发现有些初学者似乎在这里有点困扰, 就发出来供大家参考下.

首先自定义一个接口

public interface CRLocationListeneri {
	public void onLocationChanged(Location location);
}

然后些一个类, 该类需要implements LocationListener从而代替android.location.LocationListener

public class CRLocationlistener implements LocationListener {
	
	private static final String TAG = "CRLocationlistener";
	private static ArrayList LocationListeneriList = new ArrayList(
			2);


	public void onLocationChanged(Location location) {
		// TODO Auto-generated method stub
		for (i = 0; i < LocationListeneriList.size(); i++) {

			LocationListeneriList.get(i).onLocationChanged(location);
		}
	}

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

	}

	
	public synchronized static void requestUpdates(
			CRLocationListeneri LocationListeneri) {
		LocationListeneriList.add(LocationListeneri);
	}

	public synchronized static void removeUpdates(
			CRLocationListeneri LocationListeneri) {
		LocationListeneriList.remove(LocationListeneri);
	}


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

	}

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

	}

}

之后就可以通过

locationManager.requestLocationUpdates(
				LocationManager.GPS_PROVIDER, 1000, 1, mLocationListener);
CRMyLocationOverlay.enableMyLocation();

将其与多个Listener绑定, 分别对Location进行不同的处理了.
