How to disable anti-aliasing when scaling up an imageview in android?

问题

I have a pixel art that I want to scale up. The problem is when I scale it up, it gets all blurred cause of the antialiasing. Is there a way to disable antialiasing directly from xml?

回答1:

i hope its useful

Bitmap bmpSource = BitmapFactory.decodeResource(getResources(), SourceFileId);
//100 is dimension to resizing image size
//Passing filter = false will result in a blocky, pixellated image.
//Passing filter = true will give you smoother edges
Bitmap bmpScaled = Bitmap.createScaledBitmap(bmpSource, 100, 100, false); 


ImageView img = (ImageView) findViewById(Your imageView Control Id);
img.setImageBitmap(bmpScaled);

is this what u want!?
