使用ActionBar结合fragment实现导航
1，调用ActionBar的setNavigationModel(ActionBar.NAVIGATION_MODE_TABS)设置使用tabs导航
2，调用ActionBar的addTab()添加多个Tab标签
#################承载Fragment的Activity需要实现implements FirstFragment.OnFragmentInteractionListener这个接口，要不然就报错###############第二次碰到这个问题了
代码：包含原来的实现ActionBar中显示View组件（还需要在仔细看一些方法，细节）
