异常java.lang.IllegalStateException的解决

在初始化viewPagerAdapter时，显示异常。从网上找了找有两类这样的问题，一种是说给一个视图设置了两个父类，如：

TextView tv = new TextView();
layout.adView(tv);
layout2.adView(tv);这样就会报异常，需要先在其父视图中释放才能添加到另一个父视图

第二种是说：初始化时使用inflater可能出现异常

View result = inflater.inflate(R.layout.customer_layout, container);

改成下面就可以了，大概意思是不将container作为新创建的view的父视图。

View result = inflater.inflate(R.layout.customer_layout, container, false);

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

最后是我的错误代码：重复将同一个imageView添加到container中也不可以，也属于将一个view对象设置了两个父视图。

解决方案是将ImageView imageView = new ImageView(activity);挪到instantiateItem()中，即创建多个对象就可以了。

    ImageView imageView = new ImageView(activity);
　　　　　 @Override
         public Object instantiateItem(ViewGroup container, int position) {
                          x.image().bind(imageView, topimageUris.get(position));
             imageViews.add(imageView);
             container.addView(imageViews.get(position));
             return imageViews.get(position);
         }
