这是很酷一个可以展开，缩小的Viewpager。
在gradle添加依赖
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {
compile 'com.github.githubwing:ExpandableViewpager:1.0.0'
}
其次将ExpandableViewpager添加到布局。
ExpandViewPager提供了Viewpager常用方法以外。还有几个额外的方法：
//设置背景布局
mViewpager.setBackgroundView(int resId);
//设置最小高度
mViewpager.setMinHeight(int height);
//设置展开关闭监听器
mViewpager.setOnStateChangedListener(OnStateChangedListener listener);
//展开以及缩小
mViewpager.expand();
mViewpager.collaps();
