<p>自 RxJava 在2016年11月12日正式发布2.0.1版本以来也有一段事件了，其内部实现也逐渐趋于稳定，截止到笔者开始这篇文章时已更新到2.1.0。</p>
<blockquote>
<p>Version 2.1.0 is the next minor release of the 2.x era and contains the standardization of many experimental API additions from the past half a year since version 2.0.0. Therefore, the following components are now considered stable and will be supported throughout the rest of the life of RxJava 2.x.</p>
</blockquote>
<p>从版本信息来看应该是比较稳定的版本，所以这篇文章将会使用 2.1.0 版本的代码进行分析。</p>

<p>本文是 Glide 源码分析系列的第二篇，主要通过分析源码总结 Glide 的缓存机制。</p>
<h3 id="从加载流程揭开缓存机制的面纱"><a href="#从加载流程揭开缓存机制的面纱" class="headerlink" title="从加载流程揭开缓存机制的面纱"></a>从加载流程揭开缓存机制的面纱</h3><p>首先回忆一下上一篇关于 Glide 加载流程源码分析的内容，我们从 Glide.with().load().into() 这个最简单最基本的用法入手，一步步深入源码，梳理出了完整的图片加载流程。由于当时分析重点在于整体流程的把握上，所以对于缓存相关的部分都是简单带过而没有进行深入分析。首先是为了避免文章篇幅过长，其次因为缓存它不是独立的部分，它埋藏在整个加载流程的各个环节中，所以对缓存机制的理解应该建立在对整体流程清晰的把握上。</p>
<p>而在本文中，我们将从整个加载流程入手，找出缓存相关的部分，进而还原出 Glide 缓存机制的整体面貌。然后再对各个部分进行详细分析。</p>
<p>那么我们开始来看看加载流程中被我们错过的缓存操作。</p>

<p>对于 Glide 相信大家都不陌生，它是 Google 员工 bumptech 开源的一款图片加载框架，因为其简单易用的 API ，强大的功能，优秀的内存管理被 Google 官方所推荐并且被广泛运用在 Google 的开源项目中。目前 Glide 、Picasso 和 Fresco 都是比较主流图片加载框架。</p>
<p>它们的使用场景基本都是重合的，而本人对 Glide 更为熟悉，所以选取 Glide 来进行深入学习，这系列文章作为学习的总结。选取的 Glide 版本是比较新的稳定版 3.7.0 。</p>
<p>本篇是源码解析的开篇，主要分析 Glide 加载图片的基本流程。在后续的专题中再对缓存机制、生命周期监听等细节进行详细分析。</p>
