Android实现 某一个区域 的 Pinned效果

实现向上滚动屏幕到一定位置时让某个视图固定在此处，而向下滚动屏幕到此处时再恢复到原来的视图。

注意： 布局文件中 ScrollView 的第一个子View必须使用FrameLayout

• git clone https://github.com/syupo/pinned.git
• import maven project in Eclipse. <your git repository path>/pinned/share.pinned
• reference this project as a android lib project.
• make sure a frame layout is your first child of scroll view.
