智能手表应用开发全栈指南：从界面到蓝牙通信的深度实践

一、智能手表界面开发核心技术1.1 像素级还原设计稿的实现方案布局适配策略：使用ConstraintLayout实现响应式布局：androidx.constraintlayout.widget.ConstraintLayout xmlns:app="http://schemas.android.com/apk/res-auto" ImageView app:layout_constraintDimensionRatio="1:1" app:layout_constraintWidth_percent="0.3" app:layout_constraintTop_toTopOf="parent"/ /androidx.constraintlayout.widget.ConstraintLayout通过ScreenCompat处理圆形/方形表盘适配：WindowInsetsControllerCompat(window, window.decorView).apply { hide(WindowInsetsCompat.Type.systemBars()) }
