Question

简单有趣

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
    }

Taget API29。仿真器API28。Kotlin1.3.40。大约一个月前，这种乐趣奏效了。但是现在出现在“ canvas.drawBitmap”错误“软件渲染不支持硬件位图”。尝试android：hardwareAccelerated =“ false”-相同的错误。为什么？

所以，我的解决方法：

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

        return round
    }

canvas.drawBitmap-软件渲染不支持硬件位图
