基于Glide 4.4 实现加载进度监听 超大图片显示 自定义磁盘缓存路径

Glide升级V4后 导致以前封装的实用类无法编译 相关资料较少 所以根据项目需要 我们来实现三个项目中常用的功能

1：实现加载进度监听
      参考资料  Android图片加载框架最全解析（七），实现带进度的Glide图片加载功能

    

      具体实现方法参考郭霖大神的代码 这里说一下替换类 

      使用该官方的okhttp辅助库

   compile 'com.github.bumptech.glide:okhttp3-integration:4.3.1'

     将辅助库中的  OkHttpStreamFetcher 和 OkHttpUrlLoader 类   与demo中的的 OkHttpFetcher、OkHttpGlideUrlLoader类替换

     升级V4后 实现GlideModule类 里面的 registerComponents参数 发生了变化

     升级前：

public class MyGlideModule implements GlideModule {    @Override    public void applyOptions(Context context, GlideBuilder builder) {    }    @Override    public void registerComponents(Context context, Glide glide) {        OkHttpClient.Builder builder = new OkHttpClient.Builder();        builder.addInterceptor(new ProgressInterceptor());        OkHttpClient okHttpClient = builder.build();        glide.register(GlideUrl.class, InputStream.class, new OkHttpGlideUrlLoader.Factory(okHttpClient));    }}

    升级后

   

public class GlideCache implements GlideModule {      @Override    public void applyOptions(Context context, GlideBuilder builder) {         }    @Override    public void registerComponents(Context context, Glide glide, Registry registry) {        OkHttpClient.Builder builder = new OkHttpClient.Builder();        builder.addInterceptor(new ProgressInterceptor());        OkHttpClient okHttpClient = builder.build();        registry.replace(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(okHttpClient));    }}

      在manifest配置文件配置你的实现Module

    

<meta-data            android:name="com.demo.glide.GlideCache"            android:value="GlideModule" />

    使用方法

     

 ProgressInterceptor.addListener(url, new ProgressListener() {            @Override            public void onProgress(int progress) {                progressDialog.setProgress(progress);            }        });        SimpleTarget<Drawable> simpleTarget = new SimpleTarget<Drawable>() {            @Override            public void onStart() {                super.onStart();                progressDialog.show();            }            @Override            public void onResourceReady(Drawable resource, Transition<? super Drawable> transition) {                progressDialog.dismiss();                ProgressInterceptor.removeListener(url);                imageView2.setImageDrawable(resource);            }        };        RequestOptions options = new RequestOptions()                .diskCacheStrategy(DiskCacheStrategy.NONE) //测试进度实现  采用不缓存                .override(Target.SIZE_ORIGINAL, Target.SIZE_ORIGINAL);        Glide.with(this)                .load(url)                .apply(options)                .into(simpleTarget);

        实现超大图片方法（类似微博长图）

       使用最多是 SubsamplingScaleImageView

      我们在gradle中导入 

    

    compile 'com.davemorrissey.labs:subsampling-scale-image-view:3.9.0'

由于subsampling-scale-image-view不支持网络图片直接展示  但是支持图片缓存文件显示  所以我们利用Glide的缓存来实现

     

 ProgressInterceptor.addListener(path, new ProgressListener() {            @Override            public void onProgress(int progress) {                progressDialog.setProgress(progress);            }        });        SimpleTarget<File> simpleTarget = new SimpleTarget<File>() {            @Override            public void onStart() {                super.onStart();                progressDialog.show();            }            @Override            public void onResourceReady(File resource, Transition<? super File> transition) {                imageView.setImage(ImageSource.uri(resource.getAbsolutePath()),                        new ImageViewState(1.0f, new PointF(0, 0), 0));                progressDialog.dismiss();                ProgressInterceptor.removeListener(path);            }        };        Glide.with(getActivity()).asFile().load(path).into(simpleTarget);

     关于更多的subsampling-scale-image-view使用方法请参考其他

    3：自定义磁盘缓存路径

      

public class GlideCache implements GlideModule {    public static final int GLIDE_DISK_SIZE = 1024 * 1024 * 1000;    // 图片缓存子目录    public static final String GLIDE_DISK = Environment.getExternalStorageDirectory().getPath() + "/GlideV4/GlideCache";    @Override    public void applyOptions(Context context, GlideBuilder builder) {        builder.setDiskCache(new DiskLruCacheFactory(GLIDE_DISK, GLIDE_DISK_SIZE));        //builder.setLogLevel(Log.DEBUG);    }    @Override    public void registerComponents(Context context, Glide glide, Registry registry) {        OkHttpClient.Builder builder = new OkHttpClient.Builder();        builder.addInterceptor(new ProgressInterceptor());        OkHttpClient okHttpClient = builder.build();        registry.replace(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(okHttpClient));    }}

   manifest不要忘记配置
