ScaleType.FIT_XY does not preserve aspect ratio. It's not for photos, but usefull for decorative images. Try ScaleType.CENTER_CROP - your image will cropped to fit view bounds, or ScaleType.CENTER_INSIDE - your image will scaled to fit view bounds maintain the image's aspect ratio.

But it is not maintaining aspect ratio when device move in landsscape – Sunil Kumar Jun 07 '13 at 06:11
What wrong about layout? May be you should replace display.getWidth() with LayoutParams.FILL_PARENT? It seems that display.getWidth() as LayoutParams.width is a dirty hack, that works not well in all conditions. – FatalException Jun 10 '13 at 05:38
Ya right, but maintain the aspect ratio in proper way using fit-center working fine for me. Thanks – Sunil Kumar Jun 10 '13 at 05:47

Instead of using:

    imageView.setBackgroundResource(R.drawable.border);

Use :

    imageView.setImageResource(R.drawable.border);
