LayerDrawable is a type of drawable in Android that allows you to combine multiple drawable resources into a single drawable. This is useful for creating complex visuals by stacking different images, shapes, or colors on top of each other. Each layer can be individually configured, enabling developers to create rich user interfaces with minimal effort. To use a LayerDrawable, you typically define it in an XML file, specifying each layer's drawable and its corresponding properties. This approach simplifies the management of multiple drawables, making it easier to create dynamic and visually appealing applications while maintaining efficient resource usage.
