    list.add(new TowFragment());
    list.add(new OneFragment());
    mViewPager.setOffscreenPageLimit(3);//卡片数量
    mViewPager.setPageMargin(10);//两个卡片之间的距离，单位dp
    MyPageAdapter myPageAdapter = new MyPageAdapter(getChildFragmentManager(), list);
    mViewPager.setAdapter(myPageAdapter);
}

@Override

    mViewPager = (ViewPager) get(R.id.viewpager_asse);


}

@Override
