This article introduces the configuration details of Glide4 efficient loading pictures, and shares them with you as follows:
Adding glide dependencies to build. gradle
// glide Dependency
compile 'com.github.bumptech.glide:glide:4.6.1'
// glide Related annotations, generate GlideApp Code
annotationProcessor 'com.github.bumptech.glide:compiler:4.6.1'
// Glide The network library is configured to okhttp3
compile ('com.github.bumptech.glide:okhttp3-integration:4.6.1') {
transitive = false
}

Disk cache policy
缓存常量 | 说明 |
---|---|
DiskCacheStrategy.NONE | 表示不缓存任何内容。 |
DiskCacheStrategy.DAT | 表示只缓存原始图片。 |
DiskCacheStrategy.RESOURCE | 表示只缓存转换过后的图片。 |
DiskCacheStrategy.ALL | 表示既缓存原始图片,也缓存转换过后的图片。 |
DiskCacheStrategy.AUTOMATIC | 表示让Glide根据图片资源智能地选择使用哪1种缓存策略(默认选项)。 |
