使用MVP模式实现Glide回调

public interface ImageLoadCallback {
    void onImageLoaded(Bitmap image);
    void onImageLoadFailed(String error);
}

public interface ImageView {
    void showLoading();
    void showImage(Bitmap image);
    void showError(String error);
}

public class ImagePresenter {
    private ImageLoader imageLoader;
    private ImageView imageView;

    public ImagePresenter(ImageLoader imageLoader, ImageView imageView) {
        this.imageLoader = imageLoader;
        this.imageView = imageView;
    }

    public void loadImage(String imageUrl) {
        imageView.showLoading();
        
        imageLoader.loadImage(imageUrl, new ImageLoadCallback() {
            @Override
            public void onImageLoaded(Bitmap image) {
                imageView.showImage(image);
            }

            @Override
            public void onImageLoadFailed(String error) {
                imageView.showError(error);
            }
        });
    }
}

ImageLoader imageLoader = new GlideImageLoader();
ImageView imageView = new SomeImageViewImplementation();
ImagePresenter presenter = new ImagePresenter(imageLoader, imageView);

presenter.loadImage("https://example.com/image.jpg");
