fresco图片加载框架

1.首先需要导入两个依赖：
implementation ‘com.facebook.fresco:fresco:1.11.0’
implementation ‘com.facebook.fresco:animated-gif:1.10.0’
2.普通的加载图片

XML文件
<com.facebook.drawee.view.SimpleDraweeView
        android:layout_width="300dp"
        android:layout_height="300dp"
        android:id="@+id/img"        
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        />
//首先需要有一个app类并且在清单注册，这步的意思是初始化
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Fresco.initialize(this);
    }
}

//初始化之后就可以直接使用
Uri uri=Uri.parse("https://img02.sogoucdn.com/app/a/100520024/ad4741145c4dfd2c0f7c8afed8b1e029");
        img.setImageURI(uri);

3.加载GIF图片并且渐变，从模糊到清晰

XML文件
<com.facebook.drawee.view.SimpleDraweeView
        android:layout_width="300dp"
        android:layout_height="300dp"
        android:id="@+id/img"
        app:fadeDuration="5000"
        
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        />


//设置GIF动图
        BaseControllerListener<ImageInfo> baseControllerListener = new BaseControllerListener<ImageInfo>() {
            @Override
            public void onFinalImageSet(String id, ImageInfo imageInfo, Animatable animatable) {
                animatable.start();
            }

            @Override
            public void onFailure(String id, Throwable throwable) {
                Toast.makeText(MainActivity.this, "加载失败", Toast.LENGTH_SHORT).show();
            }
        };
        AbstractDraweeController controller = Fresco.newDraweeControllerBuilder()
                .setUri(uri)
                .setAutoPlayAnimations(true)   //播放gif 图片
                .setControllerListener(baseControllerListener)                
                .build();
        imgs.setController(controller);
