本文实例为大家分享了XListView实现刷新加载的具体代码，供大家参考，具体内容如下

MainActivity.java

protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 pager = findViewById(R.id.viewpager);
 group = findViewById(R.id.group);

 li = new ArrayList<>();
 li.add(new Afragment());
 li.add(new Bfragment());
 li.add(new Cfragment());
 li.add(new Dfragment());

 pager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {
  @Override
  public Fragment getItem(int position) {
  return li.get(position);
  }

  @Override
  public int getCount() {
  return li.size();
  }
 });

 group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(RadioGroup radioGroup, int i) {

  switch (i){
   case R.id.r1:
   pager.setCurrentItem(0);
   break;
   case R.id.r2:
   pager.setCurrentItem(1);
   break;
   case R.id.r3:
   pager.setCurrentItem(2);
   break;
   case R.id.r4:
   pager.setCurrentItem(3);
   break;
  }
  }
