main fragment layout:

set up view and event on your fragment like this:

        mViewPaper = (ViewPager) view.findViewById(R.id.viewpager);
        mViewPaper.setAdapter(adapder);

        mPageGroup = (RadioGroup) view.findViewById(R.id.page_group);
        mPageGroup.setOnCheckedChangeListener(this);

        mViewPaper.addOnPageChangeListener(this);

       *************************************************
       *************************************************

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
    }

    @Override
    public void onPageSelected(int position) {
        // when current page change -> update radio button state
        int radioButtonId = mPageGroup.getChildAt(position).getId();
        mPageGroup.check(radioButtonId);
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }

    @Override
    public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
        // when checked radio button -> update current page
        RadioButton checkedRadioButton = (RadioButton)radioGroup.findViewById(checkedId);
        // get index of checked radio button
        int index = radioGroup.indexOfChild(checkedRadioButton);

        // update current page
        mViewPaper.setCurrentItem(index), true);
    }
