解析AndroidProject 加载圆角图片 GlideApp加载网络图片

POOPE

演示效果

核心代码

普通图片

GlideApp.with(this)
          .load("https://www.baidu.com/img/bd_logo.png")
          .into(mImageView);

圆形图片

GlideApp.with(this)
          .load("https://www.baidu.com/img/bd_logo.png")
          .circleCrop()
          .into(mImageView);

圆角图片

GlideApp.with(this)
          .load("https://www.baidu.com/img/bd_logo.png")
          .transform(new RoundedCorners((int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
              20, getResources().getDisplayMetrics())))
          .into(mImageView);

引用依赖

build.gradle

// 图片加载框架：https://github.com/bumptech/glide
  // 官方使用文档：https://muyangmin.github.io/glide-docs-cn/
  implementation 'com.github.bumptech.glide:glide:4.12.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.12.0'

⭐由于以上加载的为网络图片，引入网络请求框架以及网络权限

// 网络请求框架：https://github.com/getActivity/EasyHttp
  implementation 'com.hjq:http:9.0'
  // OkHttp 框架：https://github.com/square/okhttp
  // noinspection GradleDependency
  implementation 'com.squareup.okhttp3:okhttp:3.12.12'

添加权限

AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

⭐此时加载了Glide 依赖，但仍然无法使用GlideApp
参考以下博文：GlideApp的由来
Glide4.0源码全解析（一），GlideAPP和.with()方法背后的故事
Glide4.0源码全解析（二），load()背后的故事
Glide4.0源码全解析（三），into()方法背后的故事
主要解决方法：创建一个类extends AppGlideModule 添加 @GlideModule 注解
