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);

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。
1 ImageView imageView = new ImageView(activity);
@Override 2 public Object instantiateItem(ViewGroup container, int position) { 3 4 x.image().bind(imageView, topimageUris.get(position)); 5 imageViews.add(imageView); 6 container.addView(imageViews.get(position)); 7 return imageViews.get(position); 8 }
异常java.lang.IllegalStateException的解决
