Android 开源库 - Fresco

这里仅仅给个如何使用的示例，至于源码剖析可以移步Fresco源码分析的系列文章。

配置

• build.gradle

//Fresco
compile 'com.facebook.fresco:fresco:0.14.1'
//Maven
// https://mvnrepository.com/artifact/com.facebook.fresco/
//WebP Not Animated
//compile group: 'com.facebook.fresco', name: 'webpsupport', version: '0.14.1'
//WebP Animated
compile group: 'com.facebook.fresco', name: 'webpsupport', version: '0.14.1'
compile group: 'com.facebook.fresco', name: 'animated-webp', version: '0.14.1'
// GIF
compile group: 'com.facebook.fresco', name: 'animated-gif', version: '0.14.1'

TIPS: 虽然这里没有加入okhttp的依赖，但是fresco 0.14.1 会自动依赖okhttp(3.3.0)
当然如果你手动指定了okhttp的版本，这里会自动替换
比如这样指定

// OkHttp
compile 'com.squareup.okhttp3:okhttp:3.4.2'
// OkIo
compile 'com.squareup.okio:okio:1.11.0'

• AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="okhttp.mutex.com.okhttpdemo">
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        android:name=".OkhttpApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

资源文件activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="okhttp.mutex.com.okhttpdemo.MainActivity">
        <com.facebook.drawee.view.SimpleDraweeView
            android:id="@+id/simple_drawee_view"
            android:layout_width="141dp"
            android:layout_height="146dp"
            android:layout_centerHorizontal="true" />
</ScrollView>

Java原文件MainActivity.java

public class MainActivity extends AppCompatActivity {
    private static final String WEBP = "http://7xinl9.com1.z0.glb.clouddn.com/Boston-City-Flow.webp";
    private static final String WEBP_ANIMATED = "http://7xinl9.com1.z0.glb.clouddn.com/BladeRunner.webp";
    private static final String JPG = "http://7xinl9.com1.z0.glb.clouddn.com/20160425150855.png";
    private static final String GIF = "http://7xinl9.com1.z0.glb.clouddn.com/10.gif";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initContentView();
    }
    private void initContentView() {
        SimpleDraweeView view = (SimpleDraweeView) findViewById(R.id.simple_drawee_view);
        DraweeController controller = Fresco.newDraweeControllerBuilder()
                .setUri(Uri.parse(GIF))
                .setAutoPlayAnimations(true)
                .build();
        view.setController(controller);
    }
}

验证结果

经验证，Fresco-0.14.1支持JPG，PNG，GIF，Webp，Animated WebP等常见的图片格式。
Tools：JPG Converter to Webp
