 private Fragment getCFragment(){
 
        Log.d(TAG,"Primary="+getSupportFragmentManager().getPrimaryNavigationFragment());//主要导航Fragment 
        Log.d(TAG,"Fragment by id ="+getSupportFragmentManager().findFragmentById(R.id.container));
        Log.d(TAG,"Fragment="+getSupportFragmentManager().getFragments().get(0));
        return   getSupportFragmentManager().findFragmentById(R.id.container);
    }

    public Fragment getPrimaryFragment(Class<?> clazz) {
        for (Fragment fragment : getCFragment().getChildFragmentManager().getFragments())         {
          if (clazz.isAssignableFrom(fragment.getClass())) {
                return fragment;
            }
           }
            return null;
