log信息如下：10-10 12:31:14.186: E/AndroidRuntime(22835): java.lang.IllegalStateException: The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged! Expected adapter item count: 0, found: 4 Pager id: com.example.app:id/viewpager Pager class: class android.support.v4.view.ViewPager Problematic adapter: class com.example.Share.ViewPagerAdapter

解决方法 http://www.cnblogs.com/ivan240/archive/2013/07/23/3208570.html：

在初始化ViewPager时，应先给Adapter初始化内容后再将该adapter传给ViewPager，
如果不这样处理，在更新adapter的内容后，应该调用一下adapter的notifyDataSetChanged方法，
否则在ADT22以上使用会报The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged的异常，
具体原因可参考：http://stackoverflow.com/questions/16756131/fragmentstatepageradapter-stopped-working-after-updating-to-adt-22
