安卓中PullToRefreshListview添加頭部viewpage

//這個我也不知道幹啥的反正下面的getLayoutInflater（）這個方法要他
  Bundle bundle=new Bundle();
  
  AbsListView.LayoutParams layoutParams = new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.WRAP_CONTENT);
 
 View header = getLayoutInflater(bundle).inflate(R.layout.child_viewpager, refresh_list_view, false);
  //在這獲取viewPager控件並配置
  viewPager=   header.findViewById(R.id.vpp);
  //設置適配器
  viewPager.setAdapter(new Viewadapter(getActivity(),list,handler));
  //viewPager.setCurrentItem(Integer.MAX_VALUE%2);
  //handler自動輪播
  handler.sendEmptyMessageDelayed(0,2000);
  //給header配置上佈局
  header.setLayoutParams(layoutParams);
  //獲取到listview控件
  ListView lv = refresh_list_view.getRefreshableView();
  //添加頭佈局
  lv.addHeaderView(header);
  //給refresh_list_view適配
 setAdapter();
