如何在 Glide 中的缓存图像上应用动画

Question

我想用Glide动画来展示图片。我正在从服务器下载这张图片。从服务器下载动画时动画工作正常，但从 Glide 缓存中获取图像时动画不工作

requestOptions.skipMemoryCache(true);
requestOptions.diskCacheStrategy(DiskCacheStrategy.ALL);

请检查下面我的代码

RequestOptions requestOptions = new RequestOptions();
requestOptions.timeout((int) NetworkParam.CONNECTION_TIME_OUT);
requestOptions.placeholder(R.drawable.img_blue_shirt);
requestOptions.priority(Priority.HIGH);
requestOptions.signature(new ObjectKey(String.valueOf(imgName)));
//requestOptions.skipMemoryCache(true);
requestOptions.diskCacheStrategy(DiskCacheStrategy.NONE);

//requestOptions.error(R.drawable.img_blue_shirt);
try {
    Glide.with(imageView.getContext().getApplicationContext())
         .load(imgUrl)
         .transition(GenericTransitionOptions.with(R.anim.anim_slide_in_left))
         .apply(requestOptions)
         .into(imageView);
} catch (Exception ex) {
    ex.printStackTrace();
}

Answer 1

By default, Glide will not animate the image when loading it. If images are cached on disk, Glide will animate. To change that, define a custom TransitionFactory and pass it in with DrawableTransitionOptions.

有关示例实现，请参阅淡入淡出工厂：https://github.com/bumptech/glide/blob/master/library/src/main/java/com/bumptech/glide/request/transition/DrawableCrossFadeFactory.java

Answer 2

是的，我在这里得到了答案，我们无法在 glide 中对缓存图像应用动画有关更多信息，请查看下方 link

Answer 3

根据文档 here，在 Glide v4 中，您可以实施和应用自定义 TransitionFactory。

对于始终交叉渐变，在 Kotlin 中您可以：

实现TransitionFactory接口

class DrawableAlwaysCrossFadeFactory : TransitionFactory<Drawable> {
  private val resourceTransition: DrawableCrossFadeTransition = DrawableCrossFadeTransition(300, true) //customize to your own needs or apply a builder pattern
  override fun build(dataSource: DataSource?, isFirstResource: Boolean): Transition<Drawable> {
    return resourceTransition
  }
}

将其作为过渡应用

GlideApp.with(this)
  .load(url)
  .transition(DrawableTransitionOptions.with(DrawableAlwaysCrossFadeFactory()))
  .into(image)

Answer 4

要在 glide 4.10 中应用图像更改过渡，请使用

Glide.with(this).load(artwork)
                            ..transition(DrawableTransitionOptions.withCrossFade())
                            .into(playerBackground);
