viewpager 、fragment 遇到的问题

标签：

1、关键字：viewpager 获取 某一个viewpager中的某一个 view

ViewPagerAdapter viewPagerAdapters = (ViewPagerAdapter) viewpager.getAdapter();
LinearLayout linearLayout = (LinearLayout)  viewPagerAdapters.instantiateItem(null, currentItem);

2、获取fragment中的listview中的headview

代码如下

LinearLayout ll = (LinearLayout)  viewPagerAdapters.instantiateItem(null, currentItem);
		if(ll==null){
			System.err.println(ll);
			return;
		}
		ListView listview = (ListView) ll.getChildAt(0);
		HeaderViewListAdapter adapter2 = (HeaderViewListAdapter) listview.getAdapter();
		HorizontalScrollView teachingStratehs = (HorizontalScrollView) adapter2.getView(0, null, listview);
		

代码如下

@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {	
		 if (null != rootView) {
	            ViewGroup parent = (ViewGroup) rootView.getParent();
	            if (null != parent) {
	                parent.removeView(rootView);
	            }
	        } else {
	            rootView = inflater.inflate(R.layout.news_fragment, null);
	            setupView(rootView);// 控件初始化
	        }
	        return rootView;		
	}
