为什么监听器没有绑定到我分配给它的对象？

Question

for (int i = 0; i < mapSize[0]; i++) {
    for (int j = 0; j < mapSize[1]; j++) {
        hashCodes[i][j] = new Image(emptyField);
        int[] targetField = new int[2];
        targetField[0] = i;
        targetField[1] = j;
        hashCodes[i][j].addListener(new InputListener() {
            @Override
            public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) {
                return true;
            }

            @Override
            public void touchUp(InputEvent event, float x, float y, int pointer, int button) {
                System.out.println("Empty Field clicked" + Arrays.toString(targetField));
                for (Image[] imageRow : hashCodes) {
                    for (Image actualImage : imageRow) {
                        System.out.print(actualImage.hashCode() + " ");
                    }
                    System.out.println();
                }
                if (MarvelousMashup.useInfinityStone) {
                    MarvelousMashup.useInfinityStone = false;
                    MainMenu.client.getMessageHandler().sendUseInfinityStoneRequest
                            (MarvelousMashup.activeCharacter,
                                    getActualEntity(MarvelousMashup.activeCharacter).getPosition(),
                                    targetField,
                                    getStone(MarvelousMashup.useInfinityStoneID));
                }
            }
        });
        tempField.addActor(hashCodes[i][j]);
    }
}

我正在为每个 Actor 分配一个侦听器。但是无论我点击哪个空白字段，每次点击的字段对我来说都是一样的，尽管每个 Actor 都是不同的。

我是不是做错了什么？因为据我了解，每个演员都应该有自己的听众，而不是所有人都是同一个听众。

尝试直接将 targetField 添加到侦听器并使用构造函数对其进行初始化。

for (int i = 0; i < mapSize[0]; i++) {
    for (int j = 0; j < mapSize[1]; j++) {
        hashCodes[i][j] = new Image(emptyField);
        hashCodes[i][j].addListener( new MyInputListener( i, j ) );
// rest of code...


class MyInputListener extends InputListener {
    int [] targetField = new int[2];
    InputListener( int i, int j ) {
      targetField[0] = i;
      targetField[1] = j;
    }
    @Override
    public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) {
       return true;
    }

    @Override
    public void touchUp(  // etc...

为什么监听器没有绑定到我分配给它的对象？

Why isn't the listener bound to the object I am assigning it to?

java

hashcode

event-listener

listener
