PagerAdapter - litonghui/TechBlog GitHub Wiki

在继承PagerAdapter 必须需要@override四个方法：

	@Override
	public Object instantiateItem(ViewGroup container, int position) {			
			RankListView rankView = new RankListView(context);
			return rankView;
	}
             
	@Override
	public int getCount() {
		return pageCount;
	}

	@Override
	public boolean isViewFromObject(View view, Object o) {
		return view == o;
	}

	@Override
	public void destroyItem(ViewGroup container, int position, Object object) {
		container.removeView((View) object);
	}
