代码实现

1、准备工作

新建一个TwoAbility如下图所示

2、新建PaySlice界面

新建xml文件，在resources的base的layout新建ability_pay.xml文件，代码如下

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:background_element="#ed6262"
    ohos:orientation="vertical">
    <Text
        ohos:height="match_parent"
        ohos:width="match_parent"
        ohos:text="支付界面"
        ohos:text_size="40vp"
        ohos:text_color="black"
        ohos:text_alignment="center"/>

</DirectionalLayout>

在slice文件目录下新建一个payslice.class文件，代码如下

package com.newdemo.myapplication.slice;

import com.newdemo.myapplication.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;

public class PaySlice  extends AbilitySlice {
    @Override
    protected void onStart(Intent intent) {
        super.onStart(intent);
        setUIContent(ResourceTable.Layout_ability_pay);
    }
}

3、config.json配置

在config.json文件找到twoability的添加“action.pay”的action，代码如下

  "skills": [
          {
            "actions": [
              "action.pay"
            ]
          }
        ],

4、xml绘画

在ability_main.xml布局添加两个text组件，第一个组件text的内容为“跳转TwoAbility”，另外一个Text组件text的内容为“以Action跳转TwoAbility的payslice”，代码如下

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:alignment="center"
    ohos:orientation="vertical">

    <Text
        ohos:id="$+id:text_StartTwoAbility"
        ohos:height="100vp"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:background_element="$graphic:background_ability_main"
        ohos:layout_alignment="horizontal_center"
        ohos:text="跳转TwoAbility"
        ohos:text_size="20vp"
        />

    <Text
        ohos:id="$+id:text_StartPayWithAction"
        ohos:height="100vp"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:background_element="#ed6262"
        ohos:layout_alignment="horizontal_center"
        ohos:text="以Action跳转TwoAbility的payslice"
        ohos:text_size="20vp"
        />

</DirectionalLayout>

mainAbilitySlice代码实现

分别实现跳转TwoAbility和以Action的调到TwoAbility的PaySlice界面，代码如下

package com.newdemo.myapplication.slice;

import com.newdemo.myapplication.ResourceTable;
import com.newdemo.myapplication.TwoAbility;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.aafwk.content.Operation;
import ohos.agp.components.Component;

public class MainAbilitySlice extends AbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        //todo 跳转到TwoAbility
        findComponentById(ResourceTable.Id_text_StartTwoAbility).setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                Intent intent=new Intent();
                Operation operation=new Intent.OperationBuilder()
                        //todo 设置BundleName
                        .withBundleName(getBundleName())
                        //todo 设置AbilityName
                        .withAbilityName(TwoAbility.class.getName())
                        .build();
                intent.setOperation(operation);
                startAbility(intent);
            }
        });
        //todo 以Action跳转到TwoAbility的pay界面
        findComponentById(ResourceTable.Id_text_StartPayWithAction).setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                Intent intent=new Intent();
                Operation operation=new Intent.OperationBuilder()
                        //todo 设置BundleName
                        .withBundleName(getBundleName())
                        //todo 设置AbilityName
                        .withAbilityName(TwoAbility.class.getName())
                        //todo 设置Action
                        .withAction("action.pay")
                        .build();
                intent.setOperation(operation);
                startAbility(intent);
            }
        });
    }

}
