android - 滑动 Java.lang.IllegalStateException : Cannot obtain size for recycled Bitmap: android. graphics.Bitmap@a4f3bcf[896x157] ARGB_8888

Question

我有一个带有一些背景的回收者 View 的 Activity 。

有时当滚动 recyclerview 并按下后退按钮时，我会收到此错误。

我有两种背景(一种是模糊的)。

要加载我使用的普通背景:

fun AppCompatImageView.loadImage(resId: Int) {
    Glide.with(context)
            .load(AppCompatResources.getDrawable(context, resId))
            .into(this)
}

要加载我使用的模糊背景:

Glide.with(mContext)
  .applyDefaultRequestOptions(RequestOptions().override(backgroundWidth, backgroundHeight))
  .asBitmap()
  .load(R.drawable.card_dog_placeholder)
  .into(object : SimpleTarget<Bitmap>() {
                                override fun onResourceReady(bitmap: Bitmap, transition: Transition<in Bitmap>?) {
                                    cardYouAreHeroBackgroundImageView.setImageBitmap(bitmap.blurRenderScript(mContext, CARD_BG_RADIUS))
                                }
                            })

fun Bitmap.blurRenderScript(context: Context, radius: Float): Bitmap {
    val rs = RenderScript.create(context)
    val blurredBitmap = copy(Bitmap.Config.ARGB_8888, true)

    val input = Allocation.createFromBitmap(rs, blurredBitmap, Allocation.MipmapControl.MIPMAP_FULL, Allocation.USAGE_SHARED)
    val output = Allocation.createTyped(rs, input.type)

    val script = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs))
    script.setInput(input)

    script.setRadius(radius)
    script.forEach(output)
    output.copyTo(blurredBitmap)
    return blurredBitmap
}

有什么想法吗？

Answer 1

确保你的代码中没有像下面这样的语句:

Glide.with(getApplicationContext()).clear(target);
Glide.get(getApplicationContext()).getBitmapPool().clearMemory();

从文档中，getBitmapPool() 返回用于临时存储 {@link android.graphics.Bitmap 的 {@link com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool} } 以便它们可以被重用以避免垃圾收集。

通常，当任何位图回收发生时，特别是当位图已经被回收时，就会发生此错误。因此，如果 getBitmapPool() 需要更好地包装在 if 中，请检查 !bitmap.isRecycled()
