在Application 中 Fresco初始化（记得注册）

public class MyApp extends Application{
    @Override
    public void onCreate() {
        super.onCreate();
        // 设置磁盘缓存
        DiskCacheConfig diskCacheConfig =  DiskCacheConfig.newBuilder(this)
                .setBaseDirectoryName("images_zjj")
                .setBaseDirectoryPath(Environment.getExternalStorageDirectory())
                .build();
        //设置磁盘缓存的配置,生成配置文件
        ImagePipelineConfig config = ImagePipelineConfig.newBuilder(this)
                .setMainDiskCacheConfig(diskCacheConfig)
                .build();
        Fresco.initialize(this,config);
    }
}
