1.鸿蒙启动动画页面视图实现效果:

通过Java线程控制计数器变量,跳转页面片段,线程的使用尤其重要,在页面数据加载,请求网络,读取文件,Java爬虫解析尤为重要,代码如下:

动画使用的是华为提供的BallPulseIndicator组件类,所以大家对Java代码创建布局也要非常了解,效果如下:

2.跳转后的页面效果,列表项和上浮按钮,和底部抽屉菜单,默认是隐藏的:

点击抽屉菜单,菜单从底部弹出,再点击底部菜单,底部菜单隐藏,效果实现如下:

3.首页动画页面Java代码实现,通过代码创建布局:

package com.example.javahm5.slice;

import com.example.javahm5.ResourceTable;
import com.wang.avi.AVLoadingIndicatorView;
import com.wang.avi.indicators.BallPulseIndicator;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.colors.RgbColor;
import ohos.agp.components.Button;
import ohos.agp.components.ComponentContainer;
import ohos.agp.components.DependentLayout;
import ohos.agp.components.element.ShapeElement;
import ohos.bundle.AbilityInfo;
import ohos.agp.components.DirectionalLayout.LayoutConfig;
import java.util.ArrayList;

public class MainAbilitySlice extends AbilitySlice {

    private DependentLayout myLayout = new DependentLayout(this);
    private ArrayList<AVLoadingIndicatorView> animatorList=new ArrayList<>();

    int  i=0;
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);

        setDisplayOrientation(AbilityInfo.DisplayOrientation.PORTRAIT);
        LayoutConfig config = new
                LayoutConfig(ComponentContainer.LayoutConfig.MATCH_PARENT,
                ComponentContainer.LayoutConfig.MATCH_PARENT);
        myLayout.setLayoutConfig(config);


        ShapeElement element = new ShapeElement();
        element.setRgbColor(new RgbColor(231,87,100));
        myLayout.setBackground(element);

        ShapeElement commonElement = new ShapeElement();
        commonElement.setRgbColor(new RgbColor(231,87,100));

        LayoutConfig ballPulseIndicatorConfig = new
                LayoutConfig(LayoutConfig.MATCH_CONTENT, LayoutConfig.MATCH_CONTENT);
        BallPulseIndicator ballPulseIndicator=new BallPulseIndicator(this);
        ballPulseIndicatorConfig.setMargins(300,700,0,0);
        ballPulseIndicator.setLayoutConfig(ballPulseIndicatorConfig);
        ballPulseIndicator.setHeight(550);
        ballPulseIndicator.setWidth(550);
        ballPulseIndicator.setBackground(commonElement);
        myLayout.addComponent(ballPulseIndicator);
        animatorList.add(ballPulseIndicator);

        super.setUIContent(myLayout);


        new  Thread(new Runnable() {
            @Override
            public void run() {

                while (i<=10)
                {
                    i++;
                    try {
                        Thread.sleep(1000);

                        if(i==10)
                        {
                            System.out.println("结束**********");
                            getUITaskDispatcher().asyncDispatch(new Runnable() {
                                @Override
                                public void run() {
                                    present(new SlidingDrawerAbilitySlice(), new Intent());
                                }
                            });

                        }
                        System.out.println("i-->"+i);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }


            }
        }).start();
    }
    private void startAllAnimator(ArrayList<AVLoadingIndicatorView> avLoadingIndicatorViews){
        for (int i = 0; i < avLoadingIndicatorViews.size(); i++) {
            avLoadingIndicatorViews.get(i).start();
        }
    }
    @Override
    public void onActive() {
        super.onActive();
        startAllAnimator(animatorList);
    }

    @Override
    public void onForeground(Intent intent) {
        super.onForeground(intent);
    }
}

 

需要集成华为提供的动画库,工程依赖目录如下:

                slidingDrawer.close();
            } else {
                slidingDrawer.open();
            }

        });
    }
    /**

    public static class TextInfo extends ItemDataModel {
