fragment中嵌套viewpager，viewpager中有多个fragment，里面fragment没有显示

fragment嵌套fragment导致里面fragment界面没有显示，例子如下：

private void InitViewPager(View parentView) {
mPager = (ViewPager) parentView.findViewById(R.id.vPager);
fragmentsList = new ArrayList<Fragment>();

fragment1 = new SortHotFragment();
fragment2 = new SortNewFragment();

fragmentsList.add(fragment1);
fragmentsList.add(fragment2);

mPager.setAdapter(new MyFragmentPagerAdapter(getActivity().getSupportFragmentManager(), fragmentsList));
mPager.setCurrentItem(0);
mPager.setOnPageChangeListener(new MyOnPageChangeListener());
}解决方法：getSupportFragmentManager()拿到里面Frament数据为空，把getSupportFragmentManager()换成getChildFragmentManager()

即可
