Question

我在一个程序包（packageShared）中有一个GpsService，我需要从另一个程序包（packageClient）中访问它。我收到“ getService（）在'packageShared.GpsService.Localbinder'中不公开。无法从外部程序包访问。”在以下行mService =（GpsService）binder.getService（）;在Android Studio中。

包装内还有另一个类。使用相同的代码可以很好地共享作品。

这是packageClient上的代码：

    // Monitors the state of the connection to the service.
private final ServiceConnection mServiceConnection = new ServiceConnection() {

    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        GpsService.LocalBinder binder = (GpsService.LocalBinder) service;
        mService = (GpsService) binder.getService();
        mBound = true;

    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        mService = null;
        mBound = false;
    }
};

这是共享包上的代码：

public class GpsService extends Service {


    public GpsService() {
    }

    other methods here...

    /**
     * Class used for the client Binder.  Since this service runs in the same process as its
     * clients, we don't need to deal with IPC.
     */
    public class LocalBinder extends Binder {
        GpsService getService() {
            return GpsService.this;
        }
    }
}

谢谢。

Answer 1

这是因为您的getService()方法是程序包可见的。您需要使其public才能从其他软件包中访问它：

public class LocalBinder extends Binder {
    public GpsService getService() {   //<-- The public keyword is added
        return GpsService.this;
    }
}

内部类：不公开，不能从外部包访问
