一、前言：
上一篇：Glide 基本使用（一）
https://www.jianshu.com/p/e350b1fa7f69
为什么选择Glide？
- Glide 轻量级
- 速度快
- 可以根据所需加载图片的大小自动适配所需分辨率的图
- 支持多种格式图片（静态webp，动态gif，jpeg，jpg，png）
- 支持多种数据源图片（url，drawable，src，file，asserts，raw）
- Google主导
Glide的封装就是各种样式，一般包括高斯模糊、圆角、圆形以及矩形圆角等，也可以多种样式混合使用。
二、自定义使用：
Glide配置
1. 在build.gradle中添加依赖：
dependencies {
//glide的依赖
compile 'com.github.bumptech.glide:glide:3.7.0'
//gradle工具类（自定义的类不用导入）
compile 'jp.wasabeef:glide-transformations:2.0.2'
}
2. 权限
如果是联网获取图片或者本地存储需要添加以下权限：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
3. 样式展示：
样式展示.pic.jpg
4. GlideUtils类：
/**
* 网络图片的工具类，自定义的图片的样式
* <p>
* (1)ImageView设置图片（错误图片）
* （2）ImageView设置图片---BitMap(不设置默认图)
* （3）设置RelativeLayout
* （4）设置LinearLayout
* （5）设置FrameLayout
* （6）高斯模糊------ RelativeLayout
* （7）高斯模糊------ LinearLayout
* （8）圆角显示图片 ImageView
