-------------------------------------------------------------------------------- 1 | ## [我的博客](http://blog.csdn.net/sw5131899/article/details/66970195) 2 | 3 | ### 手写高并发图片加载框架 4 | 5 | 图片加载框架在当前已经是相当的成熟了,想要有创新。就是需要从图片加载速度和图片缓存, 6 | 还有内存占用和生命周期监控上去做文章。glide做的就比较好。出自squre团队的良心作品。 7 | 该团队可以说是安卓业界良心,还有最近很火的retrofit和okhttp均出自该大神团队,还有很多呢。 8 | 框架用的不少,一直没什么时间去研究研究底层,总觉得还是要写一个自己用的吧,还是那句话。 9 | 至少出了问题知道在哪。也可以知道在什么地方去优化,同时也可以加强对大神框架的理解, 10 | 源码阅读能力都会有所提高。于是去参考目前比较流行的图片加载框架源码。当初的ImageLoader-universal, 11 | 还有Glide。还有facebook出品的图片加载框架。都看了看大概的思路和逻辑。 12 | 决定采用带有优先级的阻塞式队列来实现高并发图片请求。使用builder链式调度,说实话呢。要说好吧, 13 | 只能说是非常一般的框架。但是这个LemonImageLoader可以作为从未了解过图片加载框架底层的程序猿们入门的框架。 14 | 并没有采用一些太过新奇的技术。简单易懂,快速上手。 15 | 16 | ### 框架设计逻辑图 17 | 18 | ![](https://github.com/SingleShu/LemonImageLoaderDemo/raw/master/logo/ImageLoader.png) 19 | 20 | ### ImageLoaderUML 21 | 22 | ![](https://github.com/SingleShu/LemonImageLoaderDemo/raw/master/logo/ImageLoaderUML.png) 23 | 24 | 25 | 整体思路如上所示。具体的还是要看源码才行。 26 | 使用方式:导入gradle: 27 | ```Java 28 | compile 'com.singleshu888:LemonImageLoader:1.0.1' 29 | ``` 30 | 31 | ### API介绍 32 | 所有的都是通过LemonImageLoader这个类静态调用,非常方便。 33 | 34 | #### with(Context context) 35 | 设置图片加载的上下文。 36 | 37 | #### load(String url) 38 | 使用网络地址加载图片,底层自动选择图片加载器 39 | 40 | #### load(File file) 41 | 加载本地图片, 并会对图片进行压缩,适应控件。 42 | 43 | #### load(@DrawableRes int resId) 44 | 加载本地资源图片 45 | 46 | 47 | #### loaderPolicy(IPolicy policy) 48 | 加载策略,是对阻塞式队列起作用。是先进先出,还是先进后出的一个选择。像在ListView使用时希望后面的图片先加载, 49 | 就可以设置加载策略。 50 | 51 | #### cachePolicy(CacheMode mode) 52 | CacheMode是一个枚举类型。 53 | DOUBLE_CAHCE:双缓存,硬盘和内存都会存上,优先使用内存 54 | DISK_LRU_CACHE:硬盘缓存,当app卸载时会随着一起被删除 55 | MEMORY_LRU_CACHE:内存缓存,使用当前手机内存的8分之1来缓存图片。 56 | NO_CAHCE:不需要缓存。 57 | 默认是使用硬盘缓存。 58 | 59 | #### placeHolder(@DrawableRes int resId) 60 | 占位图片,失败或者加载过程显示的图片 61 | 62 | #### into(ImageView imageView) 63 | 显示的控件,具体加载逻辑。 64 | 65 | #### onFinishListener(BitmapListener bitmapListener) 66 | 图片加载完成后不显示,选择回调处理。 67 | 68 | 69 | ```Java 70 | /** 71 | * Created by ShuWen on 2017/3/27. 72 | */ 73 | 74 | public class MyApplication extends Application { 75 | @Override 76 | public void onCreate() { 77 | super.onCreate(); 78 | //使用默认的初始化全局队列 79 | GlobalConfig.initDefault(); 80 | //设置当前手机并发的线程数 81 | // GlobalConfig.init(3); 82 | 83 | } 84 | } 85 | ``` 86 | 初始化全局变量,其实就是把队列全局化。达到一个方便管理的目的。 87 | 88 | ```Java 89 | //最简单的请求图片方式 90 | LemonImageLoader.with(this) 91 | .load("https://ss3.bdstatic.com/70cFv8Sh_Q1YnxGkpoWK1HF6hhy/it/u=2940873513,4245760174&fm=23&gp=0.jpg") 92 | .into(image1); 93 | 94 | //设置占位图片 95 | LemonImageLoader.with(this) 96 | .load("https://ss0.bdstatic.com/70cFvHSh_Q1YnxGkpoWK1HF6hhy/it/u=3882497238,2506895164&fm=23&gp=0.jpg") 97 | .placeHolder(R.mipmap.ic_launcher) 98 | .into(image2); 99 | 100 | //设置占位图片,设置缓存策略,可提高用户体验 101 | //DOUBLE_CAHCE:双缓存,硬盘和内存都会存上,优先使用内存 102 | //DISK_LRU_CACHE:硬盘缓存,当app卸载时会随着一起被删除 103 | //MEMORY_LRU_CACHE:内存缓存,使用当前手机内存的8分之1来缓存图片。 104 | //NO_CAHCE:不需要缓存。 105 | //默认是使用硬盘缓存。 106 | LemonImageLoader.with(this) 107 | .load("https://ss2.bdstatic.com/70cFvnSh_Q1YnxGkpoWK1HF6hhy/it/u=272013671,438323943&fm=11&gp=0.jpg") 108 | .placeHolder(R.mipmap.ic_launcher) 109 | .cachePolicy(CacheMode.MEMORY_LRU_CACHE) 110 | .into(image3); 111 | ``` 112 | 这是一个很好的入门级图片加载框架,感兴趣的朋友可以down下去自己看看,然后自己封一个框架,可以参考Glide的原理, 113 | 创建一个空的fragment,对图片加载进行生命周期监控。这个优化很不错。大家可以去看看。觉得有用和学习价值的请给个Star。谢谢。 114 | 115 | -------------------------------------------------------------------------------- /app/.gitignore:
