And as user Anke noticed FIT_XY doesn't keep aspect ratio.Android is a Linux based operating system, designed primarily for portable devices like smartphones and tablet. The problem with ImageView is that only scaleTypes available are:ĬENTER, CENTER_CROP, CENTER_INSIDE, FIT_CENTER,FIT_END, FIT_START, FIT_XY, MATRIXĪnd to 'scale the background image (keeping its aspect ratio)' in some cases, when you want an image to fill the whole screen (for example background image) and aspect ratio of the screen is different than image's, the necessary scaleType is kind of TOP_CROP, because:ĬENTER_CROP centers the scaled image instead of aligning the top edge to the top edge of the image view and FIT_START fits the screen height and not fill the width. This is not the most performant solution, but as somebody suggested instead of background you can create FrameLayout or RelativeLayout and use ImageView as pseudo background - other elements will be position simply above it: So, in your layout file you will have something like this for your ImageView. Fill parent on the other hand is the desired setting at the beginning, because otherwise containerWidth and containerHeight will both have values equal to 0. This is necessary because setMaxHeight and setMaxWidth will only make a difference if the width and height are defined to wrap the content, not to fill the parent. In the code snippet above is bmp the Bitmap object that is to be shown and imageView is the ImageView objectĪn important thing to note is the change of the layout parameters. LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT) tBackgroundDrawable(new BitmapDrawable(copy)) NewContainerWidth = (float) containerHeight īitmap copy = Bitmap.createScaledBitmap(bmp, (int) newContainerWidth, (int) newContainerHeight, false) NewContainerHeight = newContainerWidth / h2w NewContainerWidth = newContainerHeight / h2w NewContainerHeight = (float) containerHeight NewContainerHeight = newContainerWidth * h2w

NewContainerWidth = (float) containerWidth Int containerWidth = imageView.getWidth() īoolean ch2cw = containerHeight > containerWidth įloat h2w = (float) imgHeight / (float) imgWidth įloat newContainerHeight, newContainerWidth Int containerHeight = imageView.getHeight() Here is the code snippet I used: // bmp is your Bitmap object The only solution to keep the aspect ratio I found, is to resize the ImageView after loading your drawable. Parameters as adjustViewBounds or different ScaleTypes will just be ignored. When you set the Drawable of an ImageView by using the setBackgroundDrawable method, the image will always be scaled.
