HarmonyOS鸿蒙Next中畅享50和UAWEI WATCH 3应用振动强度调节函数vibrationPattern.setIntensity()无效

HarmonyOS鸿蒙Next中畅享50和UAWEI WATCH 3应用振动强度调节函数vibrationPattern.setIntensity()无效 我在尝试开发华为畅享50和HUAWEI WATCH 3手表的震动功能的时候，发现振动强度无法调节。是设备本身不支持振动大小的调节，还是我的代码有问题？

UI界面使用的XML：

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:width="match_parent"
    ohos:height="600px"
    ohos:orientation="vertical"
    ohos:padding="32">
    <Text
        ohos:id="$+id:text"
        ohos:width="match_content"
        ohos:height="match_content"
        ohos:layout_alignment="horizontal_center"
        ohos:text="Button."
        ohos:text_size="15fp"/>
    <Button
        ohos:id="$+id:button1"
        ohos:margin="50"
        ohos:width="match_content"

        ohos:text="My name is Button."
        ohos:text_size="50"/>

        ohos:width="400px"
        ohos:max="255"
        ohos:min="0"/>
    <Button
        ohos:id="$+id:button2"
        ohos:margin="50"
        ohos:width="match_content"
        ohos:height="match_content"
        ohos:layout_alignment="horizontal_center"
        ohos:text="Stop."
        ohos:text_size="50"/>
</DirectionalLayout>

使用MainAbility调用振动函数，大概功能是点击一下上面的按钮开始振动，点击下面的按钮振动停止，中间的滑条用来调整振动强度大小。

public class MainAbility extends Ability {
    private VibratorAgent vibratorAgent = new VibratorAgent();

    private int[] intensity = {0, 100, 200, 255};
    private VibrationPattern vibrationPattern = VibrationPattern.createSingle(10000,0);

    @Override

        slider.setProgressValue(0);

        List<Integer> vibratorList = vibratorAgent.getVibratorIdList();
        if (vibratorList.isEmpty()) {
            if (text != null)
            {
                text.setText("Empty.");
            }
            return;
        }
        int vibratorId = vibratorList.get(0);

        if (button1 != null) {
            ShapeElement background = new ShapeElement();
            background.setRgbColor(new RgbColor(0, 125, 255));

            });
        }

        if (button2 != null){
            ShapeElement background = new ShapeElement();
            background.setRgbColor(new RgbColor(0, 125, 255));
            background.setCornerRadius(25);
            button2.setBackground(background);

            button2.setClickedListener(new Component.ClickedListener() {
                @Override
                public void onClick(Component component) {
                    vibratorAgent.stop();
                }
            });
        }

        if (slider != null){
            slider.setValueChangedListener(new Slider.ValueChangedListener() {

                @Override
                public void onTouchStart(Slider slider)
                {

                }

                @Override
                public void onProgressUpdated(Slider slider, int progress, boolean fromUser)
                {
                    vibratorAgent.stop();
                    vibrationPattern.setIntensity(progress);
                    text.setText(String.valueOf(vibrationPattern.getIntensity()));
                    vibratorAgent.start(vibratorId, vibrationPattern);
                }

                @Override
                public void onTouchEnd(Slider slider)
                {

                }
            });
        }
    }
}

目前设备可以振动，但是强度无法变化。就算把代码改成VibrationPattern.createPeriod(timing,intensity,3)创建振动模式振动强度也不变，无论强度如何设置。

有没有大佬解答一下？谢谢！
