Vector drawable scaling in ImageView on Android

Question

I got a kind of schematic presentation of data that is stored as a vector drawable, obtained from an original image in SVG format. I need to zoom it in and out, but after changing scaleX and scaleY parameters the image gets blurry. Can you help me change image's size with a kind of redrawing after that to make text and other elements look not like overzoomed PNG.

My code:

imageView = findViewById<ImageView>(R.id.image_view).apply {
    scaleX = 3f
    scaleY = 3f
    invalidate()
}

Answer 1

Try this code

imageView = findViewById<ImageView>(R.id.image_view).apply {
scaleX = 3f
scaleY = 3f
invalidate()
setImageBitmap(Bitmap.createScaledBitmap(bitmap, width * scaleX, height * scaleY, true))

}
