UI Design Skill

Quick Start

ConstraintLayout

xml
<androidx.constraintlayout.widget.ConstraintLayout>
    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

Jetpack Compose

kotlin
Column(modifier = Modifier.fillMaxSize().padding(16.dp)) {
    Text("Hello Compose", fontSize = 20.sp)
    Button(onClick = { }) { Text("Click Me") }
}

Material Design 3

kotlin
Scaffold(
    topBar = { TopAppBar(title = { Text("MyApp") }) }
) { padding ->
    // Content
}

Key Concepts

Constraint Types

  • •Start/End, Top/Bottom
  • •Chains (spread, packed)
  • •Guidelines
  • •Barriers
  • •Bias

Compose State

kotlin
var count by remember { mutableStateOf(0) }
Button(onClick = { count++ }) { Text("Count: $count") }

Material Components

  • •Buttons (filled, outlined, text)
  • •Cards, FABs, Dialogs
  • •Navigation patterns
  • •Theme system

Best Practices

✅ Use ConstraintLayout for efficiency ✅ Implement Material Design ✅ Test on multiple screen sizes ✅ Optimize rendering performance ✅ Support accessibility
