我们这次更新使用 Fraction

底部布局效果

#星光计划2.0# 鸿蒙 模仿boss直聘客户端更新教程-开源基础软件社区
底部布局简单说下是一个线性布局 DirectionalLayout 水平方向里面写了四个 DirectionalLayout 线性布局 然后每个线性布局里面嵌套一个inage图片空间和text文本控件来显示底部的tab 然后我们在 底部布局到上面添加了一个StackLayout 布局来装载我们的Fraction 控件

MainAbility 逻辑具体具体实现

  • 1 自己的Ability 继承 FractionAbility

public class MainAbility extends FractionAbility implements Component.ClickedListener {
    private Image job_pageimage;
    private Image company_page_image;
    private Image chat_page_image;
    private Image mine_page_image;
    private Text job_pagetext,company_page_text ,chat_page_text ,mine_page_text;
    private DirectionalLayout job_pagedl , company_page_dl, chat_page_dl,mine_page_dl;

   @Override
   public void onStart(Intent intent) {
       super.onStart(intent);
       super.setUIContent(ResourceTable.Layout_ability_main);
       addHomeFraction();
       initview();

   }
}
  • 2控件初始化、

    private void initview() {
        job_pageimage= (Image) findComponentById(ResourceTable.Id_job_page_image);
        company_page_image= (Image) 
        findComponentById(ResourceTable.Id_company_page_image);
        chat_page_image= (Image) findComponentById(ResourceTable.Id_chat_page_image);
        mine_page_image= (Image) findComponentById(ResourceTable.Id_mine_page_image);
        job_pagetext= (Text) findComponentById(ResourceTable.Id_job_page_text);
        company_page_text= (Text) findComponentById(ResourceTable.Id_company_page_text);
        chat_page_text= (Text) findComponentById(ResourceTable.Id_chat_page_text);
        mine_page_text= (Text) findComponentById(ResourceTable.Id_mine_page_text);
        job_pagedl= (DirectionalLayout) findComponentById(ResourceTable.Id_job_page_dl);
        company_page_dl= (DirectionalLayout) 
        findComponentById(ResourceTable.Id_company_page_dl);
        chat_page_dl= (DirectionalLayout) findComponentById(ResourceTable.Id_chat_page_dl);
        mine_page_dl= (DirectionalLayout) findComponentById(ResourceTable.Id_mine_page_dl);
        job_pagedl.setClickedListener(this);
        company_page_dl.setClickedListener(this);
        chat_page_dl.setClickedListener(this);
        mine_page_dl.setClickedListener(this);

    }
  • 3 点击事件
   @Override
    public void onClick(Component component) {
        switch (component.getId()){
            case ResourceTable.Id_job_page_dl:
                job_pageimage.setPixelMap(ResourceTable.Media_ic_main_tab_find_pre);
                company_page_image.setPixelMap(ResourceTable.Media_ic_main_tab_company_nor);
                chat_page_image.setPixelMap(ResourceTable.Media_ic_main_tab_contacts_nor);
                mine_page_image.setPixelMap(ResourceTable.Media_ic_main_tab_my_nor);
                job_pagetext.setTextColor(Color.GREEN);
                company_page_text.setTextColor(Color.GRAY);
                chat_page_text.setTextColor(Color.GRAY);
                mine_page_text.setTextColor(Color.GRAY);
                layoutShow(0);

                break;

                company_page_image.setPixelMap(ResourceTable.Media_ic_main_tab_company_pre);
                chat_page_image.setPixelMap(ResourceTable.Media_ic_main_tab_contacts_nor);
                mine_page_image.setPixelMap(ResourceTable.Media_ic_main_tab_my_nor);

                mine_page_text.setTextColor(Color.GREEN);
                layoutShow(3);
                break;
            default:
                break;
        }
    }
  • 4多个Fraction切换逻辑

   public  void  layoutShow(int  code){
        switch (code){
            case 0:
            getFractionManager()
                        .startFractionScheduler()
                        .replace(ResourceTable.Id_mainstack, new JobFraction())
                        .submit();

            break;
            case 1:
            getFractionManager()
                        .startFractionScheduler()
                        .replace(ResourceTable.Id_mainstack, new CompanyFraction())
                        .submit();


            break;
          case 2:
          getFractionManager()
                      .startFractionScheduler()
                      .replace(ResourceTable.Id_mainstack, new MessageFraction())
                      .submit();

           break;
            case 3:
          getFractionManager()
                        .startFractionScheduler()
                        .replace(ResourceTable.Id_mainstack, new MinepageFraction())
                        .submit();

             break;
            default:
            break;
        }
    }
  • 5 默认添加的Fraction

   private void  addHomeFraction(){
        getFractionManager()
                .startFractionScheduler()
                .add(ResourceTable.Id_mainstack, new JobFraction())
                .submit();
    }

整个MainAbility 逻辑就比较清晰了我们通过监听底部tab切换的点击事件回调方法我们调用FractionAbility 里面的 replace 和add方法来切换Fraction 和默认加载主页的Fraction 来实现了我们的上面的效果还做到了代码的解耦 我们具体的每个碎片页面的逻辑我们就可以在每个独立的Fraction 单独去实现即可。
##具体的fraction的内部逻辑我们简单说一下

  • 公司模块

    布局文件

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

    <ListContainer
        ohos:id="$+id:jop_page_list"
        ohos:height="match_parent"
        ohos:width="match_parent">
    </ListContainer>
</DirectionalLayout>

java逻辑代码

package com.example.tablist.fraction;
import com.example.tablist.ResourceTable;
import com.example.tablist.bean.PositionInfo;
import com.example.tablist.config.Api;
import com.example.tablist.provider.PositionProvider;
import com.google.gson.Gson;
import ohos.aafwk.ability.fraction.Fraction;
import ohos.aafwk.content.Intent;

import ohos.agp.components.ComponentContainer;
import ohos.agp.components.LayoutScatter;
import ohos.agp.components.ListContainer;
import java.util.List;
/***

 */
public class AttentionFraction extends Fraction {
    private PositionProvider positionProvider;
    private ListContainer listContainer;
    @Override
    protected Component onComponentAttached(LayoutScatter scatter, ComponentContainer container, 
                  Intent intent) {
        Component component=scatter.parse(ResourceTable.Layout_fraction_attention,container,false);
        return component;
    }
    protected void onStart(Intent intent) {
        super.onStart(intent);
        listContainer= (ListContainer) 
        getFractionAbility().findComponentById(ResourceTable.Id_jop_page_list);
        getPostition();
    }
    public  void  getPostition(){
        Gson gson=new Gson();
        PositionInfo positionInfo=gson.fromJson(Api.getPositioninfo(),PositionInfo.class);
        List<PositionInfo.DataBean> list=positionInfo.getData();
        positionProvider=new PositionProvider(list,  getFractionAbility());
        listContainer.setItemProvider(positionProvider);
    }
}

几个fraction其实比较·简单都是加载本地死数据显示在listContainer 控件上面,其他几个fraction因为逻辑都差不多我这边就不展开一个一个讲 有兴趣的同学可以下载完整代码去查阅 。

顶部的导航问题

之前那一版顶部导航我们也没有去掉 其实这个很容易我们只需要在config.json文件中添加如下代码即可

  "metaData":{      "customizeData":[        {          "name": "hwc-theme",          "value": "androidhwext:style/Theme.Emui.Light.NoTitleBar",          "extra": ""        }      ]    }

#星光计划2.0# 鸿蒙 模仿boss直聘客户端更新教程-开源基础软件社区
到此鸿蒙模仿boss直聘客户端就讲完了 其他页面的实现都差别不大大家可以去下载完整代码查阅 这次算是更新教程。之前教程因为个人知识疏漏说以给大家补上 以免给各位同学造成误导 实在不好意思

最后总结

鸿蒙里面提供的 Fraction(字面意思小部分)用法和安卓里面的fragment(碎片页)用法差不多 都是不能单独显示要依附于视图 。生命周期也比较类似 Fraction解决了我们常用app开发中多个tab切换的问题 ,所以这次使用 Fraction 控件 来更新了之前模仿 boss直聘项目,在这里我为之前的文章里面的描述错误给华为和各位同学道歉。当然 Fraction 也有缺陷 在实际开发中,我们可能需要让Fraction嵌套Fraction,目前鸿蒙还不支持Fraction嵌套Fraction。想信华为会尽快解决这个问题 我们也希望华为越来越好 王者归来 最后希望我的文章能帮助到各位解决问题 ,以后我还会贡献更多有用的代码分享给大家。各位同学如果觉得文章还不错 ,麻烦给关注和star,小弟在这里谢过啦!
