书籍页面需要显示轮播图组件，上网找了个现成封装好的，感谢这个哥们儿 http://blog.csdn.net/stevenhu_223/article/details/45577781
down下来用到看书中，是封装在fragment里的，我是在BookView中动态调用的，调用方式：
LayoutInflater lif = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View lubotuView = lif.inflate(R.layout.lunbotu, null); CycleViewPager cycleViewPager = (CycleViewPager) ((Activity) context).getFragmentManager().findFragmentById(R.id.lunbotuCycle); LinearLayout lunbotuLL = (LinearLayout) lubotuView.findViewById(R.id.lunbotuLL); addView(lubotuView);
好使，成功调用。
但是在翻页过程中，第二次翻到此页就崩溃了，崩溃信息：

一看就是fragment重复调用，造成了这个错误
解决方案1：所以用完了得remove掉，在CycleViewPager这个fragment中添加个ondestroy方法，当ondestroy销毁时remove此frg
public void onDestroyView() {
super.onDestroyView();
FragmentManager fm = getActivity().getSupportFragmentManager();
Fragment fragment = (fm.findFragmentById(R.id.cyclepic));
FragmentTransaction ft = fm.beginTransaction();
ft.remove(fragment);
ft.commit();
}
测试，不好使，Sh*t
解决方案2：优化oncreate生命周期，如果之前创建过，就删除，老一套：<span style="white-space:pre"> </span>public CycleViewPager() {
}
private static View rootView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// View view =
// LayoutInflater.from(getActivity()).inflate(R.layout.view_cycle_viewpager_contet,
// null);
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try {
rootView = LayoutInflater.from(getActivity()).inflate(R.layout.view_cycle_viewpager_contet, null);
} catch (InflateException e) {
}
测试，不好使，double Sh*t
解决方案3：这些都不好使，那还试试那个remove的，经过了漫长的逻辑方面的探索，终于锁定在adapter中，移除所有view之前remove
int childCount0 = viewHolder.ll.getChildCount();
for (int i = 0; i < childCount0; i++) {
View v = viewHolder.ll.getChildAt(i);
BookView bv = (BookView) v;
int bvChildCount = bv.getChildCount();
for (int j = 0; j < bvChildCount; j++) {
View bvv = bv.getChildAt(j);
if(bvv instanceof LinearLayout){
if(bvv.getId() == R.id.lunbotuLL){
FragmentManager fm = ((Activity) c).getFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.lunbotuCycle);
FragmentTransaction ft = fm.beginTransaction();
ft.remove(fragment);
ft.commit();
}
}
}
}
viewHolder.ll.removeAllViews();
测试，还tm不好使，triple Sh*t
解决方法4：思考了一下，逻辑肯定是对的，还是报错的话，是不是ft.commit这个方法不执行啊，
上网搜到了一篇文章http://blog.csdn.net/picasso_l/article/details/50994143 ，按照文章说法，添加了一个
fm.executePendingTransactions();即 立即执行 ！
测试，好使！
贴一下http://blog.csdn.net/picasso_l/article/details/50994143 这个博客的内容，当做记录，对博主表示感谢：
FragmentTransaction是异步的，commit()仅是相当于把操作加入到FragmentManager的队列，然后FragmentManager会在某一个时刻来执行，并不是立即执行。所以，真正开始执行commit()时，如果Activity的生命周期发生了变化，比如走到了onPause，或者走到了onStop，或者onDestroy都走完了，那么就会报出IllegalStateException。
这个地方确实是很坑的，我在做一个功能，需要从FragmentA跳转到FragmentB，然后调用FragmentB的刷新方法，那我的思路是从FragmentA和B的MainActivity中将A隐藏，将B显示，然后调用刷新。
于是我先将A隐藏B显示

然后，再switchFragment之后调用FragmentB的刷新功能，但是问题出现了，发现FragmentB里面的一些空间没有初始化，打了log之后发现，初始化在我的初始化在我的刷新功能后面执行，查了资料发现，FragmentTransaction的commit方法是异步的，难怪～
解决方法：executePendingTransactions
在用FragmentTransaction.commit()方法提交FragmentTransaction对象后，会在进程的主线程中，用异步的方式来执行。如果想要立即执行这个等待中的操作，就要调用这个方法（只能在主线程中调用）。要注意的是，所有的回调和相关的行为都会在这个调用中被执行完成，因此要仔细确认这个方法的调用位置。
于是我重写switchFragment方法
