使用动画开发指导
========

本篇中的所有示例仅提供核心接口的调用方法，完整的示例工程请参考[AnimationNDK](https://gitcode.com/openharmony/applications_app_samples/tree/master/code/DocsSample/ArkUISample/AnimationNDK)。

#### 使用属性动画

该示例主要演示了如何通过全局[animateTo](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-arkui-nativemodule-arkui-nativeanimateapi-1#animateto)接口添加属性动画。NDK接口开发的UI界面挂载到ArkTS主页面的完整流程可参考[接入ArkTS页面](https://developer.huawei.com/consumer/cn/doc/harmonyos-guides/ndk-access-the-arkts-page)。

*   需要执行的动画属性变化必须写在[ArkUI\_ContextCallback](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-arkui-nativemodule-arkui-contextcallback)中的callback中。
    
*   需要执行的动画属性，必须在执行动画之前设置过。
    

1.  在.ets文件中创建[NodeContent](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/js-apis-arkui-nodecontent)，把NodeContent作为参数输出到Native方法中。
    
    // 初始化NodeContent对象。
    private rootSlot = new NodeContent();
    @State @Watch('changeNativeFlag') showNative: boolean = false;
    // ...
    changeNativeFlag(): void {
      // ...
      if (this.showNative) {
        // 传递NodeContent对象用于Native创建组件的挂载显示
        nativeNode?.createNativeRoot(this.rootSlot);
      } else {
        // ...
      }
    }
    
2.  解析NodeContent，转换为C中的[ArkUI\_NodeContentHandle](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-arkui-nativemodule-arkui-nodecontent8h)对象。
    
    // 获取NodeContent
    ArkUI\_NodeContentHandle contentHandle;
    OH\_ArkUI\_GetNodeContentFromNapiValue(env, args\[0\], &contentHandle);
    
3.  获取[ArkUI\_NativeAnimateAPI\_1](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-arkui-nativemodule-arkui-nativeanimateapi-1)对象。
    
    // 获取ArkUI\_NativeAnimateAPI\_1接口
    ArkUI\_NativeAnimateAPI\_1 \*animateApi = nullptr;
    OH\_ArkUI\_GetModuleInterface(ARKUI\_NATIVE\_ANIMATE, ArkUI\_NativeAnimateAPI\_1, animateApi);
    
4.  设置[ArkUI\_AnimateOption](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-arkui-nativemodule-arkui-animateoption)参数，通过提供的C方法设置对应的参数。
    
    // 设置动画参数
    ArkUI\_AnimateOption \*option = OH\_ArkUI\_AnimateOption\_Create();
    OH\_ArkUI\_AnimateOption\_SetDuration(option, NUM\_2000); // NUM\_2000 = 2000
    OH\_ArkUI\_AnimateOption\_SetTempo(option, 1.1);
    OH\_ArkUI\_AnimateOption\_SetCurve(option, ARKUI\_CURVE\_EASE);
    ArkUI\_CurveHandle cubicBezierCurve = OH\_ArkUI\_Curve\_CreateCubicBezierCurve(0.5f, 4.0f, 1.2f, 0.0f);
    // 设置动画的动画曲线，优先于OH\_ArkUI\_AnimateOption\_SetCurve生效
    OH\_ArkUI\_AnimateOption\_SetICurve(option, cubicBezierCurve);
    OH\_ArkUI\_AnimateOption\_SetDelay(option, NUM\_20); // NUM\_20 = 20
    OH\_ArkUI\_AnimateOption\_SetIterations(option, NUM\_1); // NUM\_1 = 1
    OH\_ArkUI\_AnimateOption\_SetPlayMode(option, ARKUI\_ANIMATION\_PLAY\_MODE\_REVERSE);
    ArkUI\_ExpectedFrameRateRange \*range = new ArkUI\_ExpectedFrameRateRange;
    range->min = NUM\_10; // NUM\_10 = 10
    range->max = NUM\_120; // NUM\_120 = 120
    range->expected = NUM\_60; // NUM\_60 = 60
    OH\_ArkUI\_AnimateOption\_SetExpectedFrameRateRange(option, range);
    
5.  设置回调参数。
    
    // 设置完成的回调
    ArkUI\_AnimateCompleteCallback \*completeCallback = new ArkUI\_AnimateCompleteCallback;
    completeCallback->type = ARKUI\_FINISH\_CALLBACK\_REMOVED;
    // 结构体AnimateData中包含ArkUI\_AnimateOption\* option和ArkUI\_CurveHandle curve
    AnimateData\* data = new AnimateData();
    data->option = option;
    data->curve = cubicBezierCurve;
    completeCallback->userData = reinterpret\_cast<void\*>(data);
    completeCallback->callback = \[\](void \*userData) {
        AnimateData\* data = reinterpret\_cast<AnimateData\*>(userData);
        if (data) {
            ArkUI\_AnimateOption\* option = data->option;
            ArkUI\_CurveHandle curve = data->curve;
            if (option) {
                OH\_ArkUI\_AnimateOption\_Dispose(option);
                OH\_LOG\_Print(LOG\_APP, LOG\_ERROR, LOG\_PRINT\_DOMAIN,
                    "Init", "CXX OH\_ArkUI\_AnimateOption\_Dispose  success!");
            }
            if (curve) {
                OH\_ArkUI\_Curve\_DisposeCurve(curve);
                OH\_LOG\_Print(LOG\_APP, LOG\_ERROR, LOG\_PRINT\_DOMAIN,
                    "Init", "CXX OH\_ArkUI\_Curve\_DisposeCurve  success!");
            }
            delete data; // 释放结构体
        }
    };
                
    // 设置闭包函数
    static bool isback = true;
    ArkUI\_ContextCallback \*update = new ArkUI\_ContextCallback;
    update->callback = \[\](void \*user) {
        // 对应的属性变化 width height
        if (isback) {
            g\_animateto\_button->SetWidth(NUM\_200); // NUM\_200 = 200
            g\_animateto\_button->SetHeight(NUM\_80); // NUM\_80 = 80
            g\_animateto\_button->SetBackgroundColor(0xFFA280FF);
        } else {
            g\_animateto\_button->SetWidth(NUM\_100); // NUM\_100 = 100
            g\_animateto\_button->SetHeight(NUM\_40); // NUM\_40 = 40
            g\_animateto\_button->SetBackgroundColor(0xFFFF2E77);
        }
        isback = !isback;
    };
    // 执行对应的动画
    animateApi->animateTo(context, option, update, completeCallback);

#### 组件出现/消失转场

该示例主要演示了如何通过[ArkUI\_NodeAttributeType](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-native-node-h#arkui_nodeattributetype)中的NODE\_ROTATE\_TRANSITION，NODE\_SCALE\_TRANSITION，NODE\_TRANSLATE\_TRANSITION属性配置转场参数，并通过[ArkUI\_NodeAttributeType](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-native-node-h#arkui_nodeattributetype)中的NODE\_TRANSFORM\_CENTER属性设置NODE\_SCALE\_TRANSITION和NODE\_ROTATE\_TRANSITION动效的中心点坐标，实现组件的插入和删除时显示过渡动效。

1.  创建可交互界面，界面中包含一个Button组件，点击可以控制转场节点的添加和移除。其中[ArkUI\_NodeContentHandle](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-arkui-nativemodule-arkui-nodecontent8h)类型节点的获取与使用可参考[接入ArkTS页面](https://developer.huawei.com/consumer/cn/doc/harmonyos-guides/ndk-access-the-arkts-page)。

        return image;
    }
    
3.  在Button的监听回调里添加转场节点上下树逻辑，以此控制转场节点的入场和出场。
    
    void OnButtonShowClicked(ArkUI\_NodeEvent \*event)
    {
        if (!event) {
            return;
        }
        if (!childNode) {
            childNode = CreateChildNode();
        }

            OH\_ArkUI\_QueryModuleInterfaceByName(ARKUI\_NATIVE\_NODE, "ArkUI\_NativeNodeAPI\_1"));
        if (g\_flag) {
            g\_flag = false;
            ArkUI\_AttributeItem labelItem = {.string = "show"};
            nodeAPI->setAttribute(buttonNode, NODE\_BUTTON\_LABEL, &labelItem);
            nodeAPI->removeChild(parentNode, childNode);
        } else {
            g\_flag = true;
            ArkUI\_AttributeItem labelItem = {.string = "hide"};
            nodeAPI->setAttribute(buttonNode, NODE\_BUTTON\_LABEL, &labelItem);

    }

2.  再创建一个设置了[ArkUI\_NodeAttributeType](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-native-node-h#arkui_nodeattributetype)中的NODE\_GEOMETRY\_TRANSITION属性的image节点，属性值与第一个image节点相同，同时为该节点设置不同的宽度、高度和位置。
    
    ArkUI\_NodeHandle CreateImageNode()
    {
        ArkUI\_NativeNodeAPI\_1 \*nodeAPI = reinterpret\_cast<ArkUI\_NativeNodeAPI\_1 \*>(
            OH\_ArkUI\_QueryModuleInterfaceByName(ARKUI\_NATIVE\_NODE, "ArkUI\_NativeNodeAPI\_1"));
        ArkUI\_NodeHandle secondImage = nodeAPI->createNode(ARKUI\_NODE\_IMAGE);
        ArkUI\_AttributeItem imageSrcItem = {.string = "/pages/common/sky.jpg"};
        nodeAPI->setAttribute(secondImage, NODE\_IMAGE\_SRC, &imageSrcItem);
        ArkUI\_NumberValue textWidthValue\[\] = {{.f32 = 200}};

                                             .size = sizeof(textWidthValue) / sizeof(ArkUI\_NumberValue)};
        nodeAPI->setAttribute(secondImage, NODE\_WIDTH, &textWidthItem);
        ArkUI\_NumberValue textHeightValue\[\] = {{.f32 = 200}};
        ArkUI\_AttributeItem textHeightItem = {.value = textHeightValue,
                                              .size = sizeof(textWidthValue) / sizeof(ArkUI\_NumberValue)};

        nodeAPI->setAttribute(secondImage, NODE\_POSITION, &positionValue\_item1);
        return secondImage;
    }
    
3.  在stack的OnImageTransitionClicked监听回调函数中添加两个节点的上下树逻辑，控制节点的上下树，确保同时只有一个节点存在，同时，当其中一个节点挂载到父节点时需要重置[ArkUI\_NodeAttributeType](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/capi-native-node-h#arkui_nodeattributetype)中的NODE\_GEOMETRY\_TRANSITION属性的值，并重新设置为原来的值。
