Question

我正在尝试在RecyclerView上使用共享元素转换，但它似乎不起作用。

这是我的适配器的一部分，我使用makeSceneTransitionAnimation()：

public void onBindViewHolder(final BookViewHolder holder, final int position) {
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(context, DetailsActivity.class);
                ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation((Activity)context , holder.smallThumbnail, "thumbnailTransition");
                context.startActivity(intent, optionsCompat.toBundle());
            }
        }
}

Answer 1

在您的适配器

中

holder.smallThumbnail.setTransitionName("thumbnailTransition");
Pair<View, String> pair1 = Pair.create((View) holder.smallThumbnail, holder.smallThumbnail.getTransitionName());

ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation((Activity) mContext, pair1, pair2);
mContext.startActivity(intent, optionsCompat.toBundle());

在您的明细活动中

getWindow().setSharedElementEnterTransition(TransitionInflater.from(this).inflateTransition(R.transition.shared_element_transation));
mainImage.setTransitionName("thumbnailTransition");

此主图像是imageview，您想要转换以前的活动缩略图

shared_element_transation在res＆gt;转换中创建一个xml

<?xml version="1.0" encoding="utf-8"?>
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500">
<changeBounds />
<fade />
</transitionSet>

适配器

holder.smallImageView.setTransitionName("transition_name");
ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation(context, holder.smallImageView, "transition_name");

Intent intent = new Intent(context, DetailActivity.class);
context.startActivity(intent, optionsCompat.toBundle());

详细活动

Picasso.with(context)
    .load(url)
    .into(bigImageView, new Callback() {
        @Override
        public void onSuccess() {
            bigImageView.setTransitionName("transition_name");
            getWindow().setSharedElementEnterTransition(TransitionInflater.from(context).inflateTransition(R.transition.shared_element_transition));
        }

        @Override
        public void onError() {

        }
