java - ImageView setScaleType not working

Question

I have an ImageView and I want to to scale CENTER_CROP. If I set the image src and scale type in XML it works great. But I need to set the image in code. The following fails to scale correctly. Instead of center cropping it stretches the image to fill the width.

imageView.setBackgroundResource(R.drawable.my_image);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);

I tried reordering these lines and I tried leaving out the setScaleType and leaving that to the XML. Neither helps.

Answer 1

setBackgroundResource sets imageView's background so it is normal behaviour that stretches...

Use setImageResource instead, it will set imageview's source so it will follow your scaleType definition.
