PullScrollView
注：本项目使用Android Studio开发
本例包含ScrollView的两种实现：
1.仿照新浪微博Android客户端个人中心的ScrollView，下拉背景伸缩回弹效果。
2.ScrollView仿IOS回弹效果。
使用示例
1、
mScrollView = (PullScrollView) findViewById(R.id.scroll_view);
mHeadImg = (ImageView) findViewById(R.id.background_img);
mScrollView.setOnTurnListener(this);
mScrollView.init(mHeadImg);
2、
获取头部View进行修改示例：
TextView tvHello = (TextView)mHeadImg.findViewById(R.id.tv_hello);
tvHello.setText("world");##Screenshots
