public abstract class JsonCallBack<T> extends AbsCallback<T> {

    public JsonCallBack(Class<T> tClass) {

    }

    @Override
    public T convertResponse(Response response) throws Throwable {
        ResponseBody body = response.body();
        String json = body.string();
        Gson gson = new Gson();
        T t = gson.fromJson(json, tClass);

Glide框架

一.Bitmap三级缓存机制

Glide.get(GlideActivity.this).clearMemory();//清除内存缓存
new Thread(new Runnable() {
                        @Override
                        public void run() {
                            Glide.get(GlideActivity.this).clearDiskCache();//清除SD卡缓存
                        }
                    }).start();

二. 加载本地SD卡图片+网络图片+资源图片+视频+GIF动图

Glide .with(this).load(地址).into(imageView);

三.加载圆形头像

         Glide.with(this)
                .load("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1562587162663&di=58b961a5726901f5d3b97f8924ddc189&imgtype=0&src=http%3A%2F%2Fb-ssl.duitang.com%2Fuploads%2Fitem%2F201811%2F10%2F20181110102045_jwqny.jpg")
                .apply(RequestOptions.bitmapTransform(new CircleCrop()))
                .into(imageView);

四.加载圆角头像

        Glide.with(this)
                .load("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1562587162663&di=58b961a5726901f5d3b97f8924ddc189&imgtype=0&src=http%3A%2F%2Fb-ssl.duitang.com%2Fuploads%2Fitem%2F201811%2F10%2F20181110102045_jwqny.jpg")
                .apply(RequestOptions.bitmapTransform(new RoundedCorners(100)))
                .into(imageView);

五，设置占位符和加载失败图片

          Glide.with(this)
             .load("http://hbimg.b0.upaiyun.com/9852feef26dcba3d807282aa5dff561b1e223de85b027-Tzv0x0_fw658")
             .apply(RequestOptions.bitmapTransform(new RoundedCorners(20)).error(R.mipmap.error).placeholder(R.drawable.ic_launcher_background))
             .into(iv);
