1、首先安装必要的开发工具

1.1通过访问https://developer.harmonyos.com/cn/develop/deveco-studio
1.2安装软件

1.3通过访问https://nodejs.org/en/download/
（注：安装Node.js按自己系统安装）

1.4安装HarmonyOS SDK


把上述都勾选中进行安装。

2、创建一个HarmonyOS项目

选择EmptyAbility（选择框中的内容是，支持的设备）

下一步

3、实现最基础的页面跳转

3.1首先进入目录下的entry/src/main/resources/base/layout/下的ability_main.xml文件

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayoutxmlns:ohos="http://schemas.huawei.com/res/ohos"ohos:height="match_parent"ohos:width="match_parent"ohos:alignment="center"ohos:orientation="vertical"><Textohos:id="$+id:text_helloworld"ohos:height="match_content"ohos:width="match_content"ohos:background_element="$graphic:background_ability_main"ohos:layout_alignment="horizontal_center"ohos:text="$string:mainability_HelloWorld"ohos:text_size="40vp"/><Buttonohos:id="$+id:button1"ohos:height="match_parent"ohos:width="match_parent"ohos:layout_alignment="horizontal_center"ohos:text="跳转按钮"ohos:text_size="50vp"></Button></DirectionalLayout>

3.2然后去目录entry/src/main/java/com.example.helloword/slice/下的MainAbilitySlice文件:

package com.example.helloword.slice;import com.example.helloword.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Button;
import ohos.agp.components.Component;
import ohos.agp.components.Text;public class MainAbilitySlice extends AbilitySlice {@Overridepublic void onStart(Intent intent) {super.onStart(intent);super.setUIContent(ResourceTable.Layout_ability_main);Text text = (Text) findComponentById(ResourceTable.Id_text_helloworld);Button button = (Button) findComponentById(ResourceTable.Id_button1);/*注释：在找组件的过程中，系统会自己加上ID_，后面的部分为自己取的名字*/button.setClickedListener(listener->present(new SecondAbilitySlice(),new Intent()));}@Overridepublic void onActive() {super.onActive();}@Overridepublic void onForeground(Intent intent) {super.onForeground(intent);}
}

3.3创建一个Slice在目录entry/src/main/java/com.example.helloword/slice/下新建一个java class取名为SecondAbilitySlice
SecondAbilitySlice文件为：

package com.example.helloword.slice;import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.colors.RgbColor;
import ohos.agp.components.DependentLayout;
import ohos.agp.components.Text;
import ohos.agp.components.element.ShapeElement;
import ohos.agp.utils.Color;public class SecondAbilitySlice extends AbilitySlice {@Overrideprotected void onStart(Intent intent) {super.onStart(intent);// 声明布局DependentLayout myLayout = new DependentLayout(this);// 设置布局宽高myLayout.setWidth(DependentLayout.LayoutConfig.MATCH_PARENT);myLayout.setHeight(DependentLayout.LayoutConfig.MATCH_PARENT);// 设置布局背景为白色ShapeElement background = new ShapeElement();background.setRgbColor(new RgbColor(255, 255, 255));myLayout.setBackground(background);// 创建一个文本Text text = new Text(this);text.setText("Hi there");text.setWidth(DependentLayout.LayoutConfig.MATCH_PARENT);text.setTextSize(100);text.setTextColor(Color.BLACK);// 设置文本的布局DependentLayout.LayoutConfig textConfig = new DependentLayout.LayoutConfig(DependentLayout.LayoutConfig.MATCH_CONTENT, DependentLayout.LayoutConfig.MATCH_CONTENT);textConfig.addRule(DependentLayout.LayoutConfig.CENTER_IN_PARENT);text.setLayoutConfig(textConfig);myLayout.addComponent(text);super.setUIContent(myLayout);}
}

3.4创建一个虚拟机

此处需要登陆，需要拥有开发者账号

选择手机（phone）

运行那个小三角就好了

4、结语

好的开始是成功的一大步！
