Generate UI Code

Generate UI Code

Overview

Create or modify HarmonyOS ArkUI pages from UI requirements. Produce usable .ets code that fits the target project’s structure, routing, resources, and design conventions.

Workflow

1. Understand the target.

   • Determine whether the user wants a new page, a component, or a modification to an existing screen.
   • Inspect nearby .ets files, resource usage, routing, and theme conventions.
   • For screenshots or vague specs, infer layout hierarchy, data states, controls, and interactions.

2. Design the ArkUI structure.

   • Choose existing project components before inventing new abstractions.
   • Map layout into ArkUI containers such as Column, Row, Stack, List, Grid, Tabs, and reusable components.
   • Define stable responsive dimensions and spacing. Avoid brittle absolute positioning unless the existing codebase requires it.

3. Implement.

   • Use ArkTS declarative UI idioms and existing imports/style patterns.
   • Use resources for strings/colors/dimensions/media when the project already does.
   • Include expected states: loading, empty, error, disabled, selected, and content overflow when applicable.
   • When adding a new page, register it in main_pages.json or the project’s route registry.

4. Verify.

   • Run the project’s build/check command when available.
   • Re-check imports, component decorators, route registration, resource references, and JSON5 syntax.
   • If visual verification is possible, inspect the rendered screen or preview; otherwise state the verification limit.

UI Quality Rules

• Match the product domain. Operational tools should be dense and scannable; consumer pages can be more expressive.
• Keep text inside containers and support long labels.
• Use icons, toggles, segmented controls, sliders, tabs, menus, and form controls where the interaction calls for them.
• Prefer clear information hierarchy over decorative effects.
• Avoid one-note palettes and generic gradient-heavy pages.
• Respect HarmonyOS interaction expectations and accessibility basics.
