description: Convert Android XML layouts to Jetpack Compose. Use when asked to migrate XML layouts, convert views to composables, or help with Compose migration. Handles layouts, widgets, attributes, styles, and resource references.

XML to Jetpack Compose Converter

Convert Android XML layouts to idiomatic Jetpack Compose code.

Conversion Process

1. Analyze the XML structure and identify root layout
2. Map each view to its Compose equivalent
3. Convert attributes to Modifier chains (order matters!)
4. Handle resource references (@string, @dimen, @color)
5. Extract styles into reusable composables or theme values

Quick Reference

Layouts

Common Widgets

Modifier Order

Order matters! Follow this sequence:
1. clickable / toggleable
2. padding (outer)
3. size / fillMaxWidth / weight
4. background / clip
5. border
6. padding (inner)

Detailed Mappings

See reference files for complete mappings:
- references/layouts.md — Layout containers
- references/widgets.md — UI components
- references/attributes.md — XML attributes to Modifiers

Output Guidelines

1. Use Material 3 — Import from androidx.compose.material3
2. Prefer built-in modifiers — Avoid custom implementations
3. Handle nullability — XML allows null text, Compose needs defaults
4. Extract dimensions — Use dimensionResource() or define in theme
5. Keep composables stateless — Hoist state to caller
6. Add Preview — Include @Preview function for each composable

Example

Input:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="16dp">

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/welcome"
        android:textSize="24sp"
        android:textStyle="bold"/>

    <Button
        android:id="@+id/action_button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:text="@string/get_started"/>
</LinearLayout>

Output:

@Composable
fun WelcomeSection(
    onGetStartedClick: () -> Unit,
    modifier: Modifier = Modifier
) {
    Column(
        modifier = modifier
            .fillMaxWidth()
            .padding(16.dp)
    ) {
        Text(
            text = stringResource(R.string.welcome),
            fontSize = 24.sp,
            fontWeight = FontWeight.Bold
        )

        Spacer(modifier = Modifier.height(8.dp))

        Button(
            onClick = onGetStartedClick,
            modifier = Modifier.fillMaxWidth()
        ) {
            Text(text = stringResource(R.string.get_started))
        }
    }
}

@Preview(showBackground = true)
@Composable
private fun WelcomeSectionPreview() {
    WelcomeSection(onGetStartedClick = {})
}

Key conversions:
- match_parent → fillMaxWidth() / fillMaxHeight()
- wrap_content → default (no modifier needed)
- layout_marginTop → Spacer between elements
- Click listeners → lambda parameters
- IDs → not needed (state hoisting instead)
