reclyerView 中的图像随着 layoutManager 的变化而变小

Question

好的，所以我有一个画廊应用程序，它可以选择将 layoutManager 更改为线性或网格或交错（我正在使用单选按钮处理这些）。它们正在工作，但由于某种原因，当我从网格更改为线性时，前几张照片由于某种原因较小。但是重新加载后它们会变得很好。

我的适配器类是：

fun setImageList(imageList: List<Hit>) {
        this.imageList = imageList
        notifyDataSetChanged()
    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {

        return ViewHolder(
            DataBindingUtil.inflate(
                LayoutInflater.from(context),
                R.layout.item_images, parent, false
            )
        )
    }

    override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
        val hit = imageList[position]
        ((holder) as ViewHolder).setBinding(hit)

                Glide.with(this)
                .load(hit.webformatURL)
                .transition(DrawableTransitionOptions.withCrossFade())
                .override(-1, -1)
                .into(this)
        
    }

    override fun getItemCount(): Int {
        return imageList.size
    }

    class ViewHolder(var binding: ItemImagesBinding) : RecyclerView.ViewHolder(
        binding.root
    )

我的 mainActivity 类：

binding = DataBindingUtil.setContentView(this, R.layout.activity_main)

        imagesModelList = emptyList()
        imagesAdapter = ImagesAdapter(this, imagesModelList, this)
        binding.recyclerView.adapter = imagesAdapter


        imagesViewModel = ViewModelProvider(this).get(ImagesViewModel::class.java)

        imagesViewModel.getImagesListObserver()?.observe(this, {
                imagesModelList = it
                imagesAdapter.setImageList(it)
            }

        })
        imagesViewModel.makeApiCall(binding.searchView.query.toString())

    }

像这样改变 layoutManager：

 fun grid(v: View) {
        binding.recyclerView.layoutManager =
            GridLayoutManager(this, 3)
    }

    fun linear(v: View) {

        binding.recyclerView.layoutManager =
            LinearLayoutManager(applicationContext)

    }

    fun staggered(v: View) {
        binding.recyclerView.layoutManager =
            StaggeredGridLayoutManager(3, LinearLayoutManager.VERTICAL)
    }

使用以下代码行代替您拥有的代码行。

                 Glide.with(this)
                .load(hit.webformatURL)
                .diskCacheStrategy(DiskCacheStrategy.NONE)
                .transition(DrawableTransitionOptions.withCrossFade())
                .override(-1, -1)
                .into(this)

图像变小可能是由于 glide 库默认进行的预缓存。
