Question

我有一个RecyclerView。 recyclerview中的行包含一个ImageView。我正在使用Glide加载图像（大小为30-80 KB /图像）。如果我从上到下滚动，最后会得到OutOfMemoryException。测试设备相当老：三星Galaxy S3。

我知道有很多类似的问题。我已经尝试了所有方法，但到目前为止还没有成功。

RecyclerView在ViewPager中的一个片段中（有2页）。

行的布局：

...
 <ImageView
    android:id="@+id/catch_pic"
    android:layout_width="0dp"
    android:layout_height="@dimen/_250sdp"
    android:layout_marginTop="8dp"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/description"/>
...

我的适配器：

...
@Override
public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder holder, int position) {
    final Catch actualCatch = mItems.get(position);

    CatchViewHolder catchHolder = (CatchViewHolder) holder;

    if (actualCatch.getCatchPic() != null && !actualCatch.getCatchPic().isEmpty()) {
        catchHolder.mCatchPic.setVisibility(View.VISIBLE);

        Glide
            .with(catchHolder.itemView.getContext())
            .load(BASE_URL_FOR_IMAGES.concat(actualCatch.getCatchPic()))
            .apply(new RequestOptions().transforms(new CenterCrop(), new RoundedCorners(30)).skipMemoryCache(true))
            .into(catchHolder.mCatchPic);
    } else {
        catchHolder.mCatchPic.setVisibility(View.GONE);
    }
}

@Override
public void onViewRecycled(@NonNull RecyclerView.ViewHolder holder) {
    super.onViewRecycled(holder);

    CatchViewHolder catchHolder = (CatchViewHolder) holder;

    Glide.with(holder.itemView.getContext()).clear(catchHolder.mCatchPic);
}
...

我慢慢发疯。谁能帮助我，错误在哪里？

如果我暂时将ViewPager限制为1个片段，则结果是相同的：
