Glide图片库基本用法及加载认证的https图片

Glide的基本用法

第一步：build.gradle中引入第三方Glide库

compile 'com.github.bumptech.glide:glide:latest.integration'

第二步：proguad-rule.pro混淆文件不进行混淆处理

#Glide-keep public class * implements com.bumptech.glide.module.GlideModule-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** {  **[] $VALUES;  public *;}

第三步：加载图片方式

public class ARGB8888 implements GlideModule {    @Override    public void applyOptions(Context context, GlideBuilder builder) {        // Apply options to the builder here.        builder.setDecodeFormat(DecodeFormat.PREFER_ARGB_8888);    }    @Override    public void registerComponents(Context context, Glide glide) {    }}

在AndroidManifest.xml

<meta-data            android:name="包名.ARGB8888"            android:value="GlideModule" />

第四步：加载显示

if (Build.VERSION.SDK_INT >= 23) {            //imageView.setImageResource(R.drawable.ic_gf_default_photo);            Glide.with(activity).load(uri).centerCrop().diskCacheStrategy(DiskCacheStrategy.ALL)                    .error(R.drawable.ic_gf_default_photo)                    .crossFade()                    .into(imageView);        } else {            Glide.with(activity).load(uri).centerCrop().diskCacheStrategy(DiskCacheStrategy.ALL)                    .placeholder(R.drawable.ic_gf_default_photo)                    .error(R.drawable.ic_gf_default_photo)                    .crossFade()                    .into(imageView);        }

Glide加载认证的https图片，okhttp加载

主要重写3个类

1、OkHttpStreamFetcher

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;    }    @Override    public 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;    }    @Override    public void cleanup() {        if (stream != null) {            try {                stream.close();            } catch (IOException e) {                // Ignored            }        }        if (responseBody != null) {            responseBody.close();        }    }    @Override    public String getId() {        return url.getCacheKey();    }    @Override    public void cancel() {        // TODO: call cancel on the client when this method is called on a background thread. See #257    }}

2、OkHttpUrlLoader

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 = new OkHttpClient();                    }                }            }            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;        }        @Override        public ModelLoader<GlideUrl, InputStream> build(Context context, GenericLoaderFactory factories) {            return new OkHttpUrlLoader(client);        }        @Override        public void teardown() {            // Do nothing, this instance doesn't own the client.        }    }    private final OkHttpClient client;    public OkHttpUrlLoader(OkHttpClient client) {        this.client = client;    }    @Override    public DataFetcher<InputStream> getResourceFetcher(GlideUrl model, int width, int height) {        return new OkHttpStreamFetcher(client, model);    }}

3、最重要的类

public class SimpleGlideModule implements GlideModule{    @Override    public void applyOptions(Context context, GlideBuilder builder)    {        // Do nothing.        builder.setDecodeFormat(DecodeFormat.PREFER_ARGB_8888);    }    @Override    public void registerComponents(Context context, Glide glide)    {        OkHttpClient.Builder builder = new OkHttpClient.Builder()                .sslSocketFactory(overlockCard().getSocketFactory())                .hostnameVerifier(new HostnameVerifier()                {                    @Override                    public boolean verify(String hostname, SSLSession session)                    {                        return true;                    }                });        glide.register(GlideUrl.class, InputStream.class, new OkHttpUrlLoader.Factory(builder.build()));    }    /**     * 忽略所有https证书     */    private SSLContext overlockCard()    {        final TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager()        {            @Override            public void checkClientTrusted(X509Certificate[] chain, String authType) throws                    CertificateException            {            }            @Override            public void checkServerTrusted(X509Certificate[] chain, String authType) throws                    CertificateException            {            }            @Override            public X509Certificate[] getAcceptedIssuers()            {                X509Certificate[] x509Certificates = new X509Certificate[0];                return x509Certificates;            }        }};        try        {            SSLContext sslContext = SSLContext.getInstance("SSL");            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());            return sslContext;        }        catch (Exception e)        {            Log.e(SimpleGlideModule.class.getSimpleName(), "ssl出现异常");            return null;        }    }}

新增问题：由于导入第三方module,导致原本好的有不行了。

一般是module中的compile 'com.github.bumptech.glide:okhttp3-integration:1.4.0@aar'，注释掉，不然会走原来加载流程
