## What it is
A collection of complete, hands-on examples teaching Android custom View development in Java, covering effects like animated submit buttons, payment password input fields, progress bars, water wave animations, and QQ-style draggable unread badges. Each example is accompanied by a tutorial article explaining the implementation.

## Use cases
- learn android custom view development through real examples
- implement a payment password input box like wechat or alipay
- create a draggable sticky unread message badge like QQ
- build animated progress bars and loading views
- add typewriter fade-in text effects to a TextView
- implement sticky header scrolling effects
- recreate the alipay home page layout and animations

## When to choose
- you are an Android developer learning custom View drawing and animation techniques
- you want copy-paste reference implementations of common custom UI effects
- you prefer learning from complete working demos with accompanying write-ups

## When to avoid
- you need a production-ready maintained UI component library with a license
- you develop for platforms other than Android
- you want Kotlin-first or Jetpack Compose examples

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: ui-components, animation, developer-tools
- domain: mobile-development, tutorials, education
- platform: jvm
- tags: android-custom-view, tutorial, demo-app, ui-animation, chinese-documentation, android, mobile
