}

3.activity

  viewPager = (ViewPager) findViewById(R.id.vp_addcar_viewpager);
    List<Fragment> fragmentList = new ArrayList<>();
    JibenxinxiFragment jibenxinxiFragment = new JibenxinxiFragment();
    BaoxianxinxiFragment baoxianxinxiFragment = new BaoxianxinxiFragment();
    fragmentList.add(jibenxinxiFragment);
    fragmentList.add(baoxianxinxiFragment);
    viewPager.setAdapter(new MyFragmentPagerAdapter(getSupportFragmentManager(), fragmentList));
    viewPager.setCurrentItem(0);
    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            if(position==0){
                rb_jibenxinxi.setChecked(true);
                rb_baoxianxinxi.setChecked(false);
            }else if(position==1){
                rb_jibenxinxi.setChecked(false);
