[android-developers] Problem with view alignment and image size

Hi,

I have to show a image in vertically center on the screen. The image is originally of big size,  but I reduce it and display it.

Problem is I have to maintain the ratio of the image like example.

Original image is of 200 X 400, then I might reduce it 100 X 200.

Again if Image is of 500 X 200 then I might reduce it 250 X 100.

Problem is that My Image doesn't have fixed width or height. How can i keep it such a way that Whenever image loads it should be vertically centered.

I tried setting android:layout_centerVertical  in xml,  but it doesn't work as in xml I have to pass layout height and width. But as i said my height / width

of image is not fixed.

Please help me with this case.
