    相信大家看到上面的巨图会很懵逼~最近产品经理朝令夕改,有点烦,要不是还有外包项目在做,就不想干了,所以忍了,先做完十一后再说,毕竟找工作还是有点折腾,需要更高的薪水和技术的沉淀。好吧,啰嗦了一把,下面开始正题,最近一直在研究glide3.7和glide4.1.1,两者的方法确实改变不少,网上给的方案大多都是浅显的使用,目前没有找到git上详细使用的开源的统一的代码,我也是查了一周的代码,最后还是搞出来了一些东西,希望可以帮到你。

    首先是glide3.7的使用,比较单一,如果你要结合okhttp一起使用,全部的代码引用如下代码:

//glide37 compile 'com.github.bumptech.glide:glide:3.7.0' compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar' compile 'com.squareup.okhttp3:okhttp:3.4.2'

    使用的话如下代码:

GlideUtil.display(context, viewHolder.iv_imgurl, ratings.getSku_p_w_picpath(), GlideOptionsFactory.get(GlideOptionsFactory.Type.RADIUS)); Glide.with(context).load(ratings.getSku_p_w_picpath()).skipMemoryCache(true).diskCacheStrategy(DiskCacheStrategy.NONE).into(viewHolder.iv_imgurl); GlideOptions glideOptions = new GlideOptions(R.drawable.ic_def_loading, R.drawable.ic_def_loading, 300); GlideUtil.display(context, viewHolder.iv1, ratings.getImg_url(), glideOptions);

    这里说一下,我封装了一下3.7的方法,可以自定义圆角,但是清理缓存的操作建议还是用原生的方法。

    可以参考之前写的demo:

    https://github.com/geeklx/MyApplication/tree/master/P009_Glide图片缓存

    3.7还是很好用的,目前项目中大家应该都在用这个版本,不过4.0出来以后大幅度修改了API让很多人望而却步,我也是因为怕被技术无形的淘汰,逼了自己一把,把4.1.1的版本API都看了一遍,整体感觉4.1.1的版本还是要好一些,如果说3.7只是基础的用法,那么4.1.1就是晋升之路,学会后你会发现,有很多市面上你见过的通用的业务都不需要你去自己写页面,glide4.1.1会给你提供很好的自定义解决方案。

    下面开始正题:当你遇到清明上河图或者微博的大图预览,你会怎么做?是不是按部就班的画页面,传值,折腾几夜,然后也做出来了,挺辛苦和费劲的。现在glide4.1.1就提供了很好的便利,再说4.1.1之前先看看3.7怎么封装它,让它也实现功能。

    Glide3.7基础用法以及大图预览放大效果:

    LargeImageViewTarget:

    OkHttpProgressGlideModule:

    }     private static Interceptor createInterceptor(final ResponseProgressListener listener) {         return new Interceptor() {             @Override             public Response intercept(Chain chain) throws IOException {                 Request request = chain.request();

            String key = url.toString();             final UIProgressListener listener = LISTENERS.get(key);             if (listener == null) {                 return;             }             //长度是错误的移除监听             if (contentLength <= bytesRead) {                 forget(key);             }             if (needsDispatch(key, bytesRead, contentLength, listener.getGranualityPercentage())) {                 handler.post(new Runnable() {                     @Override                     public void run() {                         listener.onProgress(bytesRead, contentLength);

            }             float percent = 100f * current / total;             long currentProgress = (long) (percent / granularity);             Long lastProgress = PROGRESSES.get(key);             if (lastProgress == null || currentProgress != lastProgress) {                 PROGRESSES.put(key, currentProgress);

        private final ResponseBody responseBody;         private final ResponseProgressListener progressListener;         private BufferedSource bufferedSource;         OkHttpProgre***esponseBody(HttpUrl url, ResponseBody responseBody,                                    ResponseProgressListener progressListener) {             this.url = url;

                    }                     progressListener.update(url, totalBytesRead, fullLength);                     return bytesRead;                 }             };         }     } }

    这里需要注意一下,需要延迟配置GlideModule,

    xml:

<!-- Glide与OkHttp3集成 --> <meta-data     android:name="com.example.lagerp_w_picpath_test.glide.OkHttpProgressGlideModule"     android:value="GlideModule" />

    onCreate:

final Glide glide = Glide.get(this); OkHttpProgressGlideModule a = new OkHttpProgressGlideModule(); a.registerComponents(this, glide);

    这里这样写的原因是在你加载图片的时候给加载的进度过程,自定义OkHttpProgressGlideModule,

    这里给你提供一下小细节,大部分人在后台返回色值或者UI设计0%透明度的时候烦恼,给大家记录一下透明的计算方法:

     <color name="transparent_white">#00ffffff</color>      00这两位的计算:255*50%(透明度UI会告诉你)=结果128转化成16进制就是80这两位你需要的。

    接着是Glide4.1.1的用法

    首先我把开源的代码总结出来了一个library,大家可以打成aarjar或者直接引用,下面介绍用法我是直接引用,建议大家以后打成aar方便,

    glide411library的build.gradle:

compile 'com.android.support:support-v4:26.0.0-alpha1' compile 'com.github.bumptech.glide:glide:4.1.1' compile 'com.github.bumptech.glide:compiler:4.1.1' compile "com.github.bumptech.glide:okhttp3-integration:4.1.1"

    glide411library这里就不贴代码了,给大家提供地址,大家去使用:

    https://github.com/geeklx/MyApplication/tree/master/glide411library

    自己的项目使用glide411以及支持大图功能 build.gradle:

compile 'com.android.support:appcompat-v7:26.0.0-alpha1' compile 'com.android.support:percent:26.0.0-alpha1' compile 'com.android.support:design:26.0.0-alpha1' compile 'com.android.support.constraint:constraint-layout:1.0.2' //glide411 compile 'com.github.chrisbanes:PhotoView:2.1.3' compile project(':glide411library') //largep_w_picpath compile 'com.github.bumptech.glide:glide:4.1.1' compile 'com.github.bumptech.glide:compiler:4.1.1' compile "com.github.bumptech.glide:okhttp3-integration:4.1.1" compile 'com.shizhefei:LargeImageView:1.0.9' compile 'com.github.HotBitmapGG:RingProgressBar:V1.2.2'

    首先是glidedemo411的基础使用,应该是网上目前见过的最全的吧,我猜~哈哈哈~反正所有的方法我都总结出来了,漏的话不负责~哈哈~
