主要方法

  //FragmentActivity 找控件  view_pager = (ViewPager) findViewById(R.id.view_pager);  radio_group = (RadioGroup) findViewById(R.id.radio_group);  // 通过viewPager展示Fragment  list = new ArrayList<Fragment>();list.add(new Fragment_xml());list.add(new Fragment_json());  // 适配到ViewPager上view_pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager(),list));  // 滑动页面,,,,radiobutton切换view_pager.setOnPageChangeListener(new OnPageChangeListener() {      @Override      public void onPageSelected(int arg0) {          radio_group.check(radio_group.getChildAt(arg0).getId());      }      @Override      public void onPageScrolled(int arg0, float arg1, int arg2) {      }      @Override      public void onPageScrollStateChanged(int arg0) {      }  });  // 切换radiobutton,,,页面切换radio_group.setOnCheckedChangeListener(new OnCheckedChangeListener() {      @Override      public void onCheckedChanged(RadioGroup group, int checkedId) {          switch (checkedId) {              case R.id.rb_01:                  view_pager.setCurrentItem(0, false);                  break;              case R.id.rb_02:                  view_pager.setCurrentItem(1, false);                  break;              default:                  break;          }      }  });
