Android沉浸式状态栏+图片背景+标题栏渐变+背景伸缩

Android沉浸式状态栏+图片背景+标题栏渐变+背景伸缩

今天做项目时，刚好用到了一部分Android沉浸式状态栏的技术，我就单独写了出来
该部分代码在PersonView中
首先是自定义ScrollView实现Toolbar（标题栏）渐变

效果展示图：

编程思想：

1、自定义一个类，继承自ScrollView，并重写它的 onScrollChanged 方法；

2、在 onScrollChanged 中获取 ScrollView 在Y轴的移动距离，并根据此距离改变 Toolbar(标题栏) 的透明度。
示例代码：
类：MainActivity.java
