java - 如何使用 Glide 显示带有间接链接/URL 的图像

Question

我正在尝试从 WordPress 博客页面下载博客功能图像，然后稍后加载它们。

现在，每次用户向下和向上滚动时，图像都会一次又一次地加载。任何想法......plzzz ..我尝试了很多解决方案，例如，这个: Preload multiple images with Glide

但是，它没有用。

我正在使用 implementation 'com.github.bumptech.glide:glide:3.7.0'

这是我的代码:

RecyclerViewAdapter

public void getthumbnail(String imageurl, final ImageView imageView, final int position){

    ServiceWrapper serviceWrapper = new ServiceWrapper(null);
    Call<GetThumbnail> call = serviceWrapper.getThumbnailCall(imageurl);
    call.enqueue(new Callback<GetThumbnail>() {


        @Override
        public void onResponse(Call<GetThumbnail> call, Response<GetThumbnail> response) {
            if (response.body() != null && response.isSuccessful()) {
                try {

                    if (response.body().getMediaDetails()!=null){

                       // Log.e("recycler adapter", " image is here--  " + response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl());
                       // Log.e("Full IMG SIZE - ", " THIS IS FULL IMAGE URL--  " + response.body().getMediaDetails().getSizes().getFull().getSourceUrl());

                        imagepath.add(position, response.body().getMediaDetails().getSizes().getFull().getSourceUrl());


                        Glide.with(mContext)
                                .load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
                                .diskCacheStrategy(DiskCacheStrategy.SOURCE)
                                .into(imageView);

                    }else {

                    }
                }catch (Exception e){
                   // Log.e("adapter", "fail not media tag "+ e.toString());
                }

            }
        }

        @Override
        public void onFailure(Call<GetThumbnail> call, Throwable t) {

          //  Log.e("adapter", " faile  image "+t.toString());
        }
    });

}

更新我找到这段代码并将其放在其他 Glide 代码之上，但它不起作用:

Glide.with(mContext)
                                .load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
                                .downloadOnly(new SimpleTarget<File>() {
                                    @Override
                                    public void onResourceReady(File resource, GlideAnimation<? super File> glideAnimation) {

                                    }
                                });

更新:现在我使用了这段代码，它并没有更快地下载图像:

Glide.with(mContext)
                                .load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
                                .downloadOnly(new SimpleTarget<File>() {
                                    @Override
                                    public void onResourceReady(File resource, GlideAnimation<? super File> glideAnimation) {

                                        Glide.with(mContext)
                                                .load(response.body().getMediaDetails().getSizes().getFull().getSourceUrl())
                                                .diskCacheStrategy(DiskCacheStrategy.SOURCE)
                                                .into(imageView);
                                    }
                                });

更新所以，现在我尝试将 glide 3 更新为 4.x，但在 build.gradle 中出现以下错误。

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.1.1, 27.1.0, 26.1.0. Examples include com.android.support:support-compat:27.1.1 and com.android.support:animated-vector-drawable:27.1.0 less... (⌘F1) There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion).

Answer 1

加载延迟问题和图像项目处置来自 onBindViewHolder 方法，您在该方法中调用了一个网络服务。每次滚动中出现列表项时，都会调用 onBindViewHolder 以使用正确的值初始化 View 。所以你根本不应该在这里调用网络服务(但在代码中每次都会调用)。由于 Glide 创建了一个请求队列，它保证图像只会被下载一次，因为它缓存了它们。此外，它保证在滚动过程中，如果 ImageView 在 RecyclerView 的可见区域中，则图像将被加载。

另一方面，在您的情况下到达图像 url 需要两级网络服务 api-s。所以我们应该结合Glide过程和检索图像url过程来达到最佳性能。使用 Glide-OkHttp3-Integration库，我开发了这两个级别的异步调用，使 Glide 了解您的数据流。

• 请注意，您应该清理并重建您的项目以在编译时创建GlideApp 类。

ViewAdapter.java

// some code blocks

        ((ImageTypeViewHolder) holder).title.setText(Html.fromHtml(object.title , Html.FROM_HTML_MODE_LEGACY));
        ((ImageTypeViewHolder) holder).date.setText(Html.fromHtml(object.date , Html.FROM_HTML_MODE_LEGACY));
    } else {
        // ((ImageTypeViewHolder) holder).subtitle.setText(Html.fromHtml(object.subtitle));
