导依赖
//Fresco,无论使用哪个模块的功能,都必须要添加的基础依赖
implementation 'com.facebook.fresco:fresco:0.14.1'
// 在 API < 14 上的机器支持 WebP 时,需要添加
implementation 'com.facebook.fresco:animated-base-support:0.14.1'
// 支持 GIF 动图,需要添加
implementation 'com.facebook.fresco:animated-gif:0.14.1'
implementation 'com.facebook.fresco:webpsupport:0.14.1'
// 支持 WebP 静态图及 WebP 动图,需要添加
implementation 'com.facebook.fresco:animated-webp:0.14.1'
//如果项目中使用了OkHttp需要进行替换(因为Fresco底层网络用的是okhttp,不做修改会出现jar包冲突)
implementation 'com.facebook.fresco:imagepipeline-okhttp3:0.14.1'
在application中初始化Fresco(记得在清单文件里配置application)
Fresco.initialize(this);
