 LinearLayout>

 private void initView() {//找控件
        rg = (RadioGroup) findViewById(R.id.Main_RadioGroup);
        rg.setOnCheckedChangeListener(this);
        rb_1 = (RadioButton) findViewById(R.id.rb_01);

        //初始化适配器
        adapter = new MainPagerAdapter(getSupportFragmentManager());
        viewPager.setAdapter(adapter);

        //viewpager的监听
        viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {//pager滑动的时候，根据角标radiobutton被选中
                switch (position) {

            public void onPageScrollStateChanged(int state) {

            }
        });
    }

初始化Fragment并添加到集合中

 private void initEventes() {
     Fragment1 fragment1 = new Fragment1();
     Fragment2 fragment2 = new Fragment2();
     Fragment3 fragment3 = new Fragment3();
     Fragment4 fragment4 = new Fragment4();
     fragments.add(fragment1);
     fragments.add(fragment2);
     fragments.add(fragment3);
     fragments.add(fragment4);
 }

把集合传到适配器中

 private void initGetDate() {
     adapter.getDate(fragments);
     adapter.notifyDataSetChanged();
 }

 //点击rg可以跳转
    @Override
    public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
        int current = 0;  //初始值为0
        switch (checkedId) {
            case R.id.rb_01:
                current = 0;//第一个pager界面是0
                break;

            case R.id.rb_02:
                current = 1;
                break;
            case R.id.rb_03:
                current = 2;
                break;

            case R.id.rb_04:
                current = 3;
                break;
        }
        if (viewPager.getCurrentItem() != current) {

            //vp.setCurrentItem(current);
            viewPager.setCurrentItem(current, false);

        }
    }
