Fresco图片缓存路径，圆角

创建类，类继承 Application，写出onCreate方法在方法里面

private void inidfresco() {
        DiskCacheConfig diskCacheConfig = DiskCacheConfig.newBuilder(this)
                .setBaseDirectoryName("bbb")
                .setBaseDirectoryPath(Environment.getExternalStorageDirectory())
                .build();
        ImagePipelineConfig config = ImagePipelineConfig.newBuilder(this)
                .setMainDiskCacheConfig(diskCacheConfig)
                .build();
        Fresco.initialize(this,config);
    }

圆角在布局里加上

fresco:roundAsCircle="true"
