向ViewPager动态添加时报错java.lang.IllegalStateException

    向ViewPager动态添加时报错：java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first

    在网上发现也有人遇到过这个问题，并且找到了解决方案，只需要在ViewPager的适配器中添加注释下面那段代码即可。

@Override
public Object instantiateItem(ViewGroup container, int position) {
    ImageView imageView = imageViewList.get(position % imageViewList.size());
        
    //向ViewPager中动态添加时,需用以下防止报错
    ViewGroup parent = (ViewGroup) imageView.getParent();
    if (parent != null) {
        parent.removeAllViews();
    }

    container.addView(imageView);
    return imageView;
}
