Android Kotlin Glide 滚动时图像大小发生变化

问题描述 投票：0回答：1

我使用 Google 的 Glide for Kotlin 作为 Firebase 套件的一部分。我正在从 Firebase 下载 jpg 照片。

implementation 'com.firebaseui:firebase-ui-storage:6.4.0'

当我滚动时，图像会改变大小。滚动速度越快，一些图像就越小。我尝试过

fitCenter()
但这似乎没有帮助。

        Glide.with(context!! /* context */)
            .load(figure.imagePrimaryFrontURLString)
            .apply(
                RequestOptions()
                    .placeholder(R.drawable.mytoybox_logo)
                    .fitCenter()
            )
            .into(holder.imageViewFigure)

列表项被重用，当你向下滚动时，你会绑定一个更大的图像，这使得 ImageView 布局更高（wrap_content）。当您向后滚动时，Glide 会看到更高的尺寸并尝试加载具有该尺寸的图像。仅当之前没有布局时，wrap_content 才有效，否则 Glide 会读取布局的宽度/高度并将其用作目标大小。我通常建议使用holder.imageView.layout(0,0,0,0)来重置视图/目标的大小，并表现得就像列表项刚刚膨胀一样。
