DiagonalLayout is another Android UI library aimed at enabling non-rectangular, more dynamic layout patterns: it provides a custom layout container whose sides (top, bottom, left, right) can be clipped diagonally, producing slanted, angled UI containers. This is especially useful when you want to build visually striking, non-conventional layouts — e.g. a header section on a profile screen with a diagonal bottom edge, a card with angled border, or image backgrounds slanted across the screen. The library exposes XML attributes to set the diagonal angle, direction (left/right), and position (top/bottom/left/right), plus supports elevation so that shadows and Material-style depth are preserved. You embed your standard content (images, text, child views) inside the DiagonalLayout container, and it handles clipping/drawing. ...
