Question

我在使用PIG解析xml文件时获取null值作为输出。下面是我要解析的xml文件，

此XML文件似乎没有与之关联的任何样式信息。文档树如下所示。

//Activity listens to the moment when all ImageViews have been resized  

ResizeCounter.addCounterListener(new OnResizeCounterChangeListener() {
    @Override
    public void onResizeCounterChanged() {
        if (ResizeCounter.getCounter() == 4) {
            mAnswerGridView.setVisibility(View.VISIBLE);
        }
    }
});

我的猪脚是：
