英文:
Unable to Create Listener - Trouble Passing Arguments
问题
我正试图从我的主要活动中创建并访问Observable类中的监听器，使用以下代码：
BlePropertyObservable.getInstance().addListener(this, bleIDs)
Observable类：
public synchronized void addListener(BleEvent listener, BleEventImp eventIds[]) {
if (null == listener || null == eventIds) return;
for (BleEventImp id : eventIds) {
map.put(id, listener);
}
}
接口：
public interface BleEvent {
void updateView(BleEventImp eventId, String action, Object... obj);
}
然而，我得到一个错误，显示：“无法使用提供的参数调用以下函数之一：”，我不确定如何解决这个问题。
如有建议，将不胜感激。

I'm attempting to create and access a listener in my Observable class from my primary activity using the following:
BlePropertyObservable.getInstance().addListener(this, bleIDs)
Observable Class:
public synchronized void addListener(BleEvent listener, BleEventImp eventIds[]) {
if (null == listener || null == eventIds) return;
for (BleEventImp id : eventIds) {
map.put(id, listener);
}
}
Interface:
public interface BleEvent {
void updateView(BleEventImp eventId, String action, Object... obj);
}
However I'm getting an error stating: 'None of the following functions can be called with the arguments supplied:' and I'm unsure how I can go about resolving this.
Any suggestions are appreciated.

我看到BlueToothDriverActivity没有实现BleEvent接口。您需要实现它，然后您可以将this作为listener传递给addListener(BleEvent listener, BleEventImp eventIds[])。
英文:
As I see BlueToothDriverActivity doesn't implement BleEvent interface. You need to implement it and then you can pass this to the addListener(BleEvent listener, BleEventImp eventIds[]) as listener.
