Key Concepts
Platform Design Guidelines
- iOS: Apple Human Interface Guidelines (HUD, gesture-driven, depth)
- Android: Material Design 3 (material surfaces, motion, theming)
- Cross-platform: Balance consistency with platform expectations
Responsive Layout Principles
// Android ConstraintLayout
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/title"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintWidth_max="600dp" />
<Button
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Navigation Patterns
- Tab-based: Bottom navigation for equal priorities
- Stack: Drill-down navigation
- Drawer: Side navigation for many items
- Modal: Focused tasks, forms
Accessibility (a11y)
- Minimum touch targets: 48x48dp
- Color contrast ratios (4.5:1 minimum)
- Screen reader support (TalkBack, VoiceOver)
- Content descriptions for images
- Focus management for navigation
Animation Principles
- Duration: 200-300ms for most transitions
- Easing: Accelerate/decelerate curves
- Respect motion preferences (reduce motion setting)
- 60fps target for smooth experience
