Themes, styles & more: from zero to hero
summary
Explains how Android styling actually works: the build tool aapt2 (default now) compiles attrs, themes and styles; themes can be applied per-activity or per-view with theme overlays (API21 behavior backported by appcompat to ~API14); a text appearance span only applies character-level attributes (color size typeface) and setTextAppearance is API23 or use compat; practical examples include extracting a reusable list-item style, tinting icons from theme attrs, and implementing night mode via values-night plus AppCompatDelegate.setLocalNightMode — reduces duplication by using base-theme files.
