我正在开发一个LeapMotion项目。 这是我的源代码：
import java.io.IOException;
import com.leapmotion.leap.Controller;
import com.leapmotion.leap.Listener;
public class Main {
public static void main(String[] args) {
Controller controller = new Controller();
controller.addListener(new Listener(){
@Override
public void onConnect(Controller arg0) {
super.onConnect(arg0);
System.out.print("\nOnConnect");
}
@Override
public void onDeviceChange(Controller arg0) {
super.onDeviceChange(arg0);
System.out.print("\nOnDeviceChanged");
}
@Override
public void onDisconnect(Controller arg0) {
super.onDisconnect(arg0);
System.out.print("\nOnDisconnected");
}
@Override
public void onExit(Controller arg0) {
super.onExit(arg0);
System.out.print("\nOnExit");
}
@Override
public void onFocusGained(Controller arg0) {
super.onFocusGained(arg0);
System.out.print("\nOnFocusGained");
}
@Override
public void onFocusLost(Controller arg0) {
super.onFocusLost(arg0);
System.out.print("\nOnFocusLost");
}
@Override
public void onFrame(Controller arg0) {
super.onFrame(arg0);
System.out.print("\nOnFrame");
}
@Override
public void onInit(Controller arg0) {
super.onInit(arg0);
System.out.print("\nOnInit");
}
@Override
public void onServiceConnect(Controller arg0) {
super.onServiceConnect(arg0);
System.out.print("\nOnServiceConnect");
}
@Override
public void onServiceDisconnect(Controller arg0) {
super.onServiceDisconnect(arg0);
System.out.print("\nOnServiceDisconnect");
}
});
System.out.print("\nKeep proccess until press a key");
try {
System.in.read();
} catch (IOException e) {
e.printStackTrace();
}
}
}
当我执行时，报告了胎儿错误：

但它看起来对我没用， 有人可以帮个忙吗？
答案 0 :(得分：1)
您的匿名侦听器对象正在被垃圾收集，因为您没有保留对它的引用。尝试：
import java.io.IOException;
import com.leapmotion.leap.Controller;
import com.leapmotion.leap.Listener;
public class Main {
public static void main(String[] args) {
Controller controller = new Controller();
Listener listen = new Listener(){
@Override
public void onConnect(Controller arg0) {
super.onConnect(arg0);
System.out.print("\nOnConnect");
}
@Override
public void onDeviceChange(Controller arg0) {
super.onDeviceChange(arg0);
System.out.print("\nOnDeviceChanged");
}
@Override
public void onDisconnect(Controller arg0) {
super.onDisconnect(arg0);
System.out.print("\nOnDisconnected");
}
@Override
public void onExit(Controller arg0) {
super.onExit(arg0);
System.out.print("\nOnExit");
}
@Override
public void onFocusGained(Controller arg0) {
super.onFocusGained(arg0);
System.out.print("\nOnFocusGained");
}
@Override
public void onFocusLost(Controller arg0) {
super.onFocusLost(arg0);
System.out.print("\nOnFocusLost");
}
@Override
public void onFrame(Controller arg0) {

System.out.print("\nOnFrame");
}
@Override

System.out.print("\nOnInit");
}
@Override
public void onServiceConnect(Controller arg0) {
super.onServiceConnect(arg0);
System.out.print("\nOnServiceConnect");
}
@Override
public void onServiceDisconnect(Controller arg0) {
//super.onServiceDisconnect(arg0);
System.out.print("\nOnServiceDisconnect");
}
};
controller.addListener(listen);
System.out.print("\nKeep proccess until press a key");
try {
System.in.read();
} catch (IOException e) {
e.printStackTrace();
}
}
}
或者，或许更好，从中创建一个合适的类。
（另外，没有理由在回调函数中调用super。）
