Glide :
An image loading and caching library for Android focused on smooth scrolling
安卓上专注于平滑滑动的图片加载和缓存库。
Glide有以下特点：
1.生命周期：图片的加载、GIF图片的播放，可和页面的生命周期一致。可接受Activity、Fragment、FragmentActivity、ApplicationContext。
实现原理：
Glide对每个页面维护了一个单独的RequestManager。
对于每一个Activity或Fragment，在其中添加一个RequestManagerFragment作为子Fragment，其生命周期和父组件Activity或Fragment的生命周期一致，在RequestManagerFragment中onStart、onStop、onDestroy中调用相应方法。
对于ApplicationContext，只调用了onStart方法。
优点： 可自动根据页面生命周期，开始/暂停加载图片、展示动态图片。
缺点： 会消耗更多资源。使用时如果不了解相关特性，容易出错。
2.相比Fresco，没有使用JNI
优点： 不容易出现JNI相关的错误，配置更容易
缺点： 相比Fresco，性能可能稍差，OOM的概率可能多一点
3.Bitmap解码格式：默认优先使用RGB_565，比ARGB_8888内存占用减少一半，性能好。可全局配置优先使用RGB_565或ARGB_8888，也可对某个请求单独配置。Fresco也可以支持两种编码，而Picasso只支持ARGB_8888。
4.磁盘缓存策略：默认使用了内存LRU缓存和磁盘LRU缓存。磁盘缓存支持配置缓存全尺寸、转换过的尺寸、两者都保存。可全局配置，或对某个请求单独配置。
Picasso内部只实现了内存LRU缓存，磁盘缓存直接使用了OKHTTP的缓存，只能缓存下载的原始图片，每次从磁盘加载都要转换。
5.内存缓存策略：使用了两级内存缓存，MemoryCache和ActiveResource，前者默认为一个LruResourceCache，后者是一个Map弱引用，引用了从MemoryCache中读取过的资源和从网络、硬盘下载和转换出的资源。
加载图片时先使用MemoryCache，如果没有找到则尝试从ActiveResource中获取资源。如果还是没有再从磁盘、网络获取资源。
6.BitmapPool：进行Bitmap相关的操作时，对Bitmap进行缓存和复用。默认实现的是LruBitmapPool(仅支持Android 3.0及以上版本)。
7.网络图片下载：网络图片默认使用HttpURLConnection加载（HttpUrlFetcher），可以通过注册模块的形式，设置成Volley或OkHttp等。
8.相比Fresco，不需要特定的View，直接使用ImageView即可，通用性好
9.可以暂停、继续、清除某个页面的RequestManager中所有请求。和Picasso相似（Picasso通过Tag来对Request分组进行操作）。
10.尺寸适配：默认自动根据图片尺寸加载对应的图片。Picasso则需要显示调用fit()方法。
11.图片转换：配合glide-transformations，可对图片实现裁剪，着色，模糊，滤镜等效果。
12.预加载：提供了一个ListPreloader类，可用于AbsListView的预加载
原理：ListPreloader中实现了OnScrollListener，滚动时自动计算并预加载，所加载的Target为PreloadTarget。
13.加载动态图：支持GIF和本地视频加载，并根据页面生命周期播放/暂停
14.默认网络请求使用的是httpurlconnection,同时支持自定义使用volley 或者 ok。
15.自定义多个请求的优先级，重要的图片，可以设置高的优先级，优先加载。
16.可以给url 设置一个签名，当url 指向不变，图片内容变化时，根据签名不同，去自动更换以缓存的图片，这一点是imagoader无法做到的。
17.更有一个非常优秀的特点，可以在非ImageView 类型上面加载图片。
更多优点，不一一总结，留待大家亲身使用感受。
获取Glide
首先获取Glide的jar包，可以去github下载，添加依赖，也可以使用gradle 下载。
You can download a jar from GitHub's releases page.
Or use Gradle:
repositories {mavenCentral() // jcenter() works as well because it pulls from Maven Central
}dependencies {compile 'com.github.bumptech.glide:glide:3.7.0'compile 'com.android.support:support-v4:19.1.0'
}How do I use Glide?
// For a simple view:
@Override public void onCreate(Bundle savedInstanceState) {...ImageView imageView = (ImageView) findViewById(R.id.my_image_view);Glide.with(this).load("http://goo.gl/gEgYUd").into(imageView);
}// For a simple image list:
@Override public View getView(int position, View recycled, ViewGroup container) {final ImageView myImageView;if (recycled == null) {myImageView = (ImageView) inflater.inflate(R.layout.my_image_view, container, false);} else {myImageView = (ImageView) recycled;}String url = myUrls.get(position);Glide.with(myFragment).load(url).centerCrop().placeholder(R.drawable.loading_spinner).crossFade().into(myImageView);return myImageView;
}可以看出Glide 的使用时相当简便的，添加依赖后，仅仅通过Glide.with().load().into();就可以展示远程图片。
以上便是Github上关于Glide的基本介绍，接下来我们看具体的使用。
Glide 使用起来非常简单，Glide 在Activity 、Fragment 中都可以使用，并且是通过绑定对应的对象去使用。
Glide.with(this).load(url).into(imageView);这就是最基本的使用方式 。
with() ：使Glide 的生命周期与当前对象绑定，可以是Activity Fragment Context等等。
load()：可以加载一个本地图片，或者网络图片地址，也可以是Android工程的 内部Resource 图片资源。
into()：将展示在ImageView 对象。
介绍一些常用的配置：
Glide基本方法：Glide.with(this).load(R.mipmap.bigger).into(imageView);
加载网络图片时显示的占位图：.placeholder(holderId).into(imageView);
加载失败时展示的失败图:.error(errorId).into(imageView);
淡入淡出的渐变展示过渡动画:.crossFade().into(imageView);淡入淡出的渐变展示过渡动画 crossFade(int millSeconds) 默认Glide是自动执行该方法的，淡入时间是300ms （可以自己传int 参数去调整时间），如果要禁止该效果，可以调用dontAnimate() 方法按比例缩小或者放大到ImageView宽度，居中显示:.fitCenter().into(imageView);
按比例放大图片居中显示，图片的长/宽 可能大于ImageView的长/宽:.centerCrop().into(imageView);。
priority( Priority.HIGH )：设置请求的优先级 由低到高分别为： Priority.LOW、 Priority.NORMAL、 Priority.HIGH 、 Priority.IMMEDIATE。
skipMemoryCache( true ) ：是否设置不允许内存缓存，如果是比较频繁的变化，那么可以不在内存中保存，默认是false，即允许内存缓存。
diskCacheStrategy()：设置磁盘缓存策略，因为默认情况下 Glide 不仅仅会缓存远程图片，并且会缓存适应当前View size的图片。
参数为枚举类型 有四种分辨是：
DiskCacheStrategy.NONE 什么都不缓存。
DiskCacheStrategy.SOURCE 仅仅只缓存原来的全分辨率的图像。
DiskCacheStrategy.RESULT 仅仅缓存最终的图像，即，降低分辨率后的（或者是转换后的）。
DiskCacheStrategy.ALL 缓存所有版本的图像（默认行为）。
override(int w,int h): 重新调整图片的大小。Glide 加载图片默认是适应ImageView的大小，调用该方法，可能导致图片显示小于ImageView的size。
缩略图：普通方式 .thumbnail(0.1f) 将原图缩小到10%。使用该方法需要保证ImageView的ScaleType。
高级方式通过请求一个额外的Request去请求缩略图
private void loadImageThumbnailRequest() { // setup Glide request without the into() methodDrawableRequestBuilder<String> thumbnailRequest = Glide.with( context ).load( thumbnailUrl );// pass the request as a a parameter to the thumbnail requestGlide.with( context ).load( UsageExampleGifAndVideos.gifUrl ).thumbnail( thumbnailRequest ).into( imageView);
}
将图片显示在普通View上：
public <T> void showImageOnCustomView(T t, String url, View view) {ViewTarget viewTarget = new ViewTarget<View, GlideDrawable>(view) {@Overridepublic void onResourceReady(GlideDrawable resource, GlideAnimation<? super GlideDrawable> glideAnimation) {//>=API 16 this.view.setBackground(resource.getCurrent());this.view.setBackgroundDrawable(resource.getCurrent());}};Glide.with(context).load(url).into(viewTarget);}属性动画animate()： 给图片添加动画，比如属性动画 translate、scale、alpha、rotate,又或者 Activity切换样式 这种属性动画 android.R.anim.slide_in_left
Glide .with( context ).load( url ).animate( android.R.anim.slide_in_left ) // or R.anim.zoom_in.into( imageView1 );也可以自定义xml Animation。
或者：
ViewPropertyAnimation.Animator animationObject = new ViewPropertyAnimation.Animator() { @Overridepublic void animate(View view) {// if it's a custom view class, cast it here// then find subviews and do the animations// here, we just use the entire view for the fade animationview.setAlpha( 0f );ObjectAnimator fadeAnim = ObjectAnimator.ofFloat( view, "alpha", 0f, 1f );fadeAnim.setDuration( 2500 );fadeAnim.start();}
};Glide .with( context ).load( url ).animate( animationObject ).into( imageView );
图片进行转换transform() /bitmapTransform(): 比如模糊，圆形图片 and so on。
public class BlurTransformation extends BitmapTransformation {private RenderScript rs;public BlurTransformation(Context context) {super( context );rs = RenderScript.create( context );}@Overrideprotected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {Bitmap blurredBitmap = toTransform.copy( Bitmap.Config.ARGB_8888, true );// Allocate memory for Renderscript to work withAllocation input = Allocation.createFromBitmap(rs, blurredBitmap, Allocation.MipmapControl.MIPMAP_FULL, Allocation.USAGE_SHARED);Allocation output = Allocation.createTyped(rs, input.getType());// Load up an instance of the specific script that we want to use.ScriptIntrinsicBlur script = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));script.setInput(input);// Set the blur radiusscript.setRadius(10);// Start the ScriptIntrinisicBlurscript.forEach(output);// Copy the output to the blurred bitmapoutput.copyTo(blurredBitmap);toTransform.recycle();return blurredBitmap;}@Overridepublic String getId() {return "blur";}
}Glide .with( context ).load( url ).transform( new BlurTransformation( context ) )//.bitmapTransform( new BlurTransformation( context ) ) // this would work too!.into( imageView);自定义Glide组件GlideModule 配置
/*** Instruction ：设置 MemoryCache BitmapPool DiskCache size or path&size* Created by zhangjun on 2016-8-19 17:24*/
public class CustomCachingGlideModule implements GlideModule {@Overridepublic void applyOptions(Context context, GlideBuilder builder) {MemorySizeCalculator calculator = new MemorySizeCalculator(context);int defaultMemoryCacheSize = calculator.getMemoryCacheSize();int defaultBitmapPoolSize = calculator.getBitmapPoolSize();int customMemoryCacheSize = (int) (2 * defaultMemoryCacheSize);int customBitmapPoolSize = (int) (2 * defaultBitmapPoolSize);builder.setMemoryCache(new LruResourceCache(customMemoryCacheSize));builder.setBitmapPool(new LruBitmapPool( customBitmapPoolSize) );int cacheSize100MegaBytes = 104857600;Log.e("CustomCachingGlide","32");

}在清单文件中：<meta-dataandroid:name="packageName.CustomCachingGlideModule"android:value="GlideModule" />设置网络请求库：
Glide 默认用HttpUrlConnetction去请求网络，默认提供几张请求方式 分别是Volley 和OKHttp
使用方式：
Volley在build.gradle：
dependencies { // your other dependencies// ...// Glidecompile 'com.github.bumptech.glide:glide:3.7.0'// Glide's Volley Integration compile 'com.github.bumptech.glide:volley-integration:1.4.0@aar'compile 'com.mcxiaoke.volley:library:1.0.8'
}
OK 在build.gradle:
dependencies { // your other dependencies// ...// Glidecompile 'com.github.bumptech.glide:glide:3.7.0'// Glide's OkHttp3 Integration compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar'compile 'com.squareup.okhttp3:okhttp:3.2.0'
}下面的作为了解
1.Glide请求Https ：
通过创建禁止ssl 验证的OKHttpClient来实现
public class UnsafeOkHttpClient { public static OkHttpClient getUnsafeOkHttpClient() {try {// Create a trust manager that does not validate certificate chainsfinal TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {@Overridepublic void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {}@Overridepublic void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {}@Overridepublic java.security.cert.X509Certificate[] getAcceptedIssuers() {return null;}}};// Install the all-trusting trust managerfinal SSLContext sslContext = SSLContext.getInstance("SSL");sslContext.init(null, trustAllCerts, new java.security.SecureRandom());// Create an ssl socket factory with our all-trusting managerfinal SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();OkHttpClient okHttpClient = new OkHttpClient();okHttpClient.setSslSocketFactory(sslSocketFactory);okHttpClient.setProtocols(Arrays.asList(Protocol.HTTP_1_1));okHttpClient.setHostnameVerifier(new HostnameVerifier() {@Overridepublic boolean verify(String hostname, SSLSession session) {return true;}});return okHttpClient;} catch (Exception e) {throw new RuntimeException(e);}}
}public class UnsafeOkHttpGlideModule implements GlideModule { @Overridepublic void applyOptions(Context context, GlideBuilder builder) {}@Overridepublic void registerComponents(Context context, Glide glide) {glide.register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory());}}public class OkHttpUrlLoader implements ModelLoader<GlideUrl, InputStream> {/*** The default factory for {@link OkHttpUrlLoader}s.*/public static class Factory implements ModelLoaderFactory<GlideUrl, InputStream> {private static volatile OkHttpClient internalClient;private OkHttpClient client;private static OkHttpClient getInternalClient() {if (internalClient == null) {synchronized (Factory.class) {if (internalClient == null) {internalClient = UnsafeOkHttpClient.getUnsafeOkHttpClient();}}}return internalClient;}/*** Constructor for a new Factory that runs requests using a static singleton client.*/public Factory() {this(getInternalClient());}/*** Constructor for a new Factory that runs requests using given client.*/public Factory(OkHttpClient client) {this.client = client;}@Overridepublic ModelLoader<GlideUrl, InputStream> build(Context context, GenericLoaderFactory factories) {return new OkHttpUrlLoader(client);}@Overridepublic void teardown() {// Do nothing, this instance doesn't own the client.}}private final OkHttpClient client;public OkHttpUrlLoader(OkHttpClient client) {this.client = client;}@Overridepublic DataFetcher<InputStream> getResourceFetcher(GlideUrl model, int width, int height) {return new OkHttpStreamFetcher(client, model);}
}public class OkHttpStreamFetcher implements DataFetcher<InputStream> { private final OkHttpClient client;private final GlideUrl url;private InputStream stream;private ResponseBody responseBody;public OkHttpStreamFetcher(OkHttpClient client, GlideUrl url) {this.client = client;this.url = url;}@Overridepublic InputStream loadData(Priority priority) throws Exception {Request.Builder requestBuilder = new Request.Builder().url(url.toStringUrl());for (Map.Entry<String, String> headerEntry : url.getHeaders().entrySet()) {String key = headerEntry.getKey();requestBuilder.addHeader(key, headerEntry.getValue());}Request request = requestBuilder.build();Response response = client.newCall(request).execute();responseBody = response.body();if (!response.isSuccessful()) {throw new IOException("Request failed with code: " + response.code());}long contentLength = responseBody.contentLength();stream = ContentLengthInputStream.obtain(responseBody.byteStream(), contentLength);return stream;}@Overridepublic void cleanup() {if (stream != null) {try {stream.close();} catch (IOException e) {// Ignored}}if (responseBody != null) {try {responseBody.close();} catch (IOException e) {// Ignored.}}}@Overridepublic String getId() {return url.getCacheKey();}@Overridepublic void cancel() {// TODO: call cancel on the client when this method is called on a background thread. See #257}
}
