Android ScrollableLayout实现仿简书个人中心

我是用的一个很有名气的依赖库，当然这个依赖库不是我写的，但是那个依赖库，实现起来真的好麻烦啊，我写了一个主
页，你让我导入了十多个类，和将近十个布局，还有其他依赖包，但是不知道访问量怎么会那么多。废话不多说，看下我写
的，简便不简便你说了算。

这个功能当滑到顶部的时候，标题栏置顶，当标题栏置顶，下部列表滑倒第一条目的时候，标题栏才会跟着下来

首先现导入Moudle一个依赖包：

implementation 'com.github.cpoopc:scrollablelayoutlib:1.0.1'

下面是xml布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android=""xmlns:app=""android:id="@+id/mCoordina"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/white"><com.cpoopc.scrollablelayoutlib.ScrollableLayoutandroid:id="@+id/scrollbarlayout"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><ImageViewandroid:id="@+id/mImg_headimg"android:layout_width="match_parent"android:layout_height="318dp"android:layout_alignParentTop="true"android:layout_marginTop="-100dp"android:scaleType="fitXY"android:src="@mipmap/ic_launcher" /><android.support.design.widget.TabLayoutandroid:id="@+id/tablayout"android:layout_width="match_parent"android:layout_height="36dp"app:tabMaxWidth="0dp"app:tabGravity="fill"app:tabMode="fixed"/><android.support.v4.view.ViewPagerandroid:id="@+id/viewpager"android:layout_width="match_parent"android:layout_height="match_parent"app:layout_behavior="@string/appbar_scrolling_view_behavior"></android.support.v4.view.ViewPager></com.cpoopc.scrollablelayoutlib.ScrollableLayout></android.support.design.widget.CoordinatorLayout>

下面属于我的主运行类，你换成Acitivty即可

下面就添加一个Frgment，其他的都给它一样

}
