    height = getWindowManager().getDefaultDisplay().getHeight();
    width = getWindowManager().getDefaultDisplay().getWidth();
    InitUI();
    // InitPager();
    DisplayImage();
    SetonClickListners();
}

Answer 1

Set the image view's width to MATCH_PARENT, height to WRAP_CONTENT, and scaleType to centerInside. This will make it scale keeping aspect ratio, have a width of the full screen, and stop scaling the image such that it fits on the screen.
