Fresco简单使用

首先导入依赖

implementation 'com.facebook.fresco:fresco:1.11.0'

初始化

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        //缓存路径
        DiskCacheConfig config = DiskCacheConfig.newBuilder(this)
                .setBaseDirectoryName("images")
                .setBaseDirectoryPath(Environment.getDataDirectory())
                .build();
        //设置磁盘缓存的配置并设置文件
        ImagePipelineConfig config1 = ImagePipelineConfig.newBuilder(this)
                .setMainDiskCacheConfig(config)
                .build();
        Fresco.initialize(this,config1);
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
   bind = ButterKnife.bind(this);

    builder = new GenericDraweeHierarchyBuilder(getResources());
    //静态图片网址
    path ="http://www.zhaoapi.cn/images/quarter/ad1.png";
}


@OnClick({R.id.btn_cricle,R.id.btn_radiu,R.id.btn_sclace,R.id.btn_gif,R.id.zhu,R.id.addlist,})
public void setOnClick(Button btn){
    switch (btn.getId()){
         case R.id.btn_cricle:
             //加载圆形图片
             RoundingParams params = RoundingParams.asCircle();  //形状
             GenericDraweeHierarchy hierarchy = builder.setRoundingParams(params).build();
             image.setHierarchy(hierarchy);
             image.setImageURI(path);
            break;
         case R.id.btn_radiu:
             //圆角 7dp
             RoundingParams cornersRadius = RoundingParams.fromCornersRadius(20);
             GenericDraweeHierarchy hierarchy1 = builder.setRoundingParams(cornersRadius).build();
             image.setHierarchy(hierarchy1);
             image.setImageURI(path);
             break;
         case R.id.btn_sclace:
             //设置宽高比
             image.setImageURI(path);
             ViewGroup.LayoutParams layoutParams = image.getLayoutParams();
             int width = image.getWidth();
             layoutParams.height=(int)(width*0.71);
             image.setLayoutParams(layoutParams);
             break;
         case R.id.btn_gif:
             //动图
             AbstractDraweeController controller = Fresco.newDraweeControllerBuilder()
                     .setUri(Uri.parse("http://s1.dwstatic.com/group1/M00/FD/B0/1878f20ee96e34481a404cf9e80358b7.gif"))
                     .setAutoPlayAnimations(true)
                     .setOldController(image.getController())
                     .build();
             image.setController(controller);
             Animatable animatable = image.getController().getAnimatable();
             if (animatable!=null &&  !animatable.isRunning()){
                 animatable.start();
             }
             break;
