canvas.draw位图 - 软件呈现不支持硬件位图

Question

简单的乐趣

fun getCircleBitmap(bitmap: Bitmap, recycle: Boolean): Bitmap {
        val paint = Paint()
        paint.isAntiAlias = true
        paint.color = Color.WHITE
        paint.xfermode = PorterDuffXfermode(PorterDuff.Mode.SRC_IN)
        val rect = Rect(0, 0, bitmap.width, bitmap.height)
        val rectF = RectF(rect)
        val output = Bitmap.createBitmap(bitmap.width, bitmap.height, Bitmap.Config.ARGB_8888)
        val canvas = Canvas(output)
        canvas.drawARGB(0, 0, 0, 0)
        canvas.drawOval(rectF, paint)
        canvas.drawBitmap(bitmap, rect, rect, paint)
        if (recycle) {
            bitmap.recycle()
        }
        return output
    }

塔吉特 API 29.模拟器 API 28.科特林 1.3.40。大约一个月前，这种乐趣奏效了。但是现在在"canvas.drawBitmap"错误"软件渲染不支持硬件位图"。尝试android：hardwareAccelerated d="false" - 同样的错误。为什么？

所以，我的解决方案：

fun getCircleBitmapDrawable(bitmap: Bitmap): RoundedBitmapDrawable {
        val round = RoundedBitmapDrawableFactory.create(context.resources, bitmap)
        round.isCircular = true
        round.setAntiAlias(true)
        return round
    }
