How to align ImageView to the bottom, fill its width and height, and keep its aspect ratio?

Question

Background

There are various XML attributes for ImageView to scale its content , and various layout views that allow to place views and set their sizes.

Howeve

Answer 1

You need a combination of three attributes:

android:layout_height="wrap_content"
android:scaleType="fitCenter"
android:adjustViewBounds="true"

The adjustViewBounds attribute is needed because ImageView measures itself to match the original dimensions of the drawable by default, without regard to any scaling performed according to the scale type.
