背景

HarmonyOS Next适配开发过程中难买难要参考之前逻辑，但是可能时间较长文档不全，只能参考Android或iOS代码，有些逻辑较重的场景还可以通过AI工具将Android 的Java代码逻辑转成TS完成部分复用。对于一些UI场景只能手动去写，虽然ArkUI写页面效率比较高，但是如果页面比较多，工作量也不小，官方提供了Android APK转ArkTS页面的工具，本文带大家一起体验尝试一波。

工具介绍

UI Generator用于快速生成可编译、可运行的HarmonyOS UI工程，支持基于已有UI布局文件（XML），快速生成对应的HarmonyOS UI代码，其中包含HarmonyOS基础工程、页面布局、组件及属性和资源文件等。

需要使用使用DevEco Studio 5.0.3.700及以上版本。

工具配置

在DevEco-Studio中，打开设置页面，点击插件，找到已安装的UI Generator插件后选择开启：

应用、确认后，在工具栏工具中点击“Generate Project from …"：

第一次进入需要同意用户协议：

接下来选择Android的安装包apk路径和Android SDK路径：

接着选择要转换的xml布局：

选择下一步：

这里面Destination Path为生成HarmonyOS Next公测的路径和名称，点击确认后开始转换，转换日志如下：

打开新工程，生成的页面位于entry > src > main > ets > pages目录下，可以在Previewer中查看页面预览效果。生成的新工程内的entry > src > main > resources目录包含文本、图像、颜色资源。

这里以一个简单示例为例，Android xml：

<?xml version="1.0" encoding="utf-8"?>  
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"  
            android:layout_width="match_parent"  
            android:layout_height="match_parent"  
            android:orientation="vertical">  
  
    <LinearLayout        android:id="@+id/container"  
        android:layout_width="213dp"  
        android:layout_height="wrap_content"  
        android:orientation="vertical">  
  
    </LinearLayout></ScrollView>

生成ArkTS代码：

@Entry  
@Component  
export struct activity_preview {  
  build() {  
    /*  
     * FIXME: Unhandled property 'android:orientation'  
     */    Scroll() {  
      Column()  
        .id('container')  
        .width('213vp')  
        .alignItems(HorizontalAlign.Start)  
    }  
    .align(Alignment.TopStart)  
    .width('100%')  
    .height('100%')  
  }  
}

不支持生成的组件、属性会以注释的形式给出，方便后续定位修改。

总结

虽然有些自定义组件或者属性无法直接转换，但是对于复杂页面，帮助我们生成大的框架和大部分代码也可以极大的提升我们开发效率，推荐大家尝试。
