[UWP] Windows.Devices.Sensors.Accelerometer.Shaken无效 [英] [UWP]Windows.Devices.Sensors.Accelerometer.Shaken is not working

问题描述

我正在开发Windows 10中的Accelerometer内容。请查看以下观察结果。

I am working on Accelerometer stuff in windows 10. Please find the below observations.

1。我有Windows 8应用程序，它使用Accelerometer API，并注册到Shaken事件

1. I have windows 8 app, which uses Accelerometer API, and registered to Shaken event

案例1：Windows 8.1操作系统设备收到"动摇"事件  

case 1: Windows 8.1 OS device received "Shaken" event  

案例2：未收到Widows 10（Build no 10240）"Shaken"事件

case 2: Widows 10 (Build no 10240) is not received "Shaken" event

2。我创建了示例windows 10 app，它使用了Accelerometer API，并注册了Shaken事件

2. I have created sample windows 10 app, which uses Accelerometer API, and registered to Shaken event

行为：   ;未收到寡妇10（建筑编号10240）"摇动"事件

behavior:  Widows 10 (Build no 10240) is not received "Shaken" event

我不明白这个问题。我们是否有其他API来检测"Shake"。或者它是Windows 10 OS内部问题。

I don't understood the problem. Do we have other API to detect "Shake". OR It is windows 10 OS internal Issue.

注意：我使用的是DELL Latitude 10 - ST2e

Note: I am using DELL Latitude 10 - ST2e

嗨帕拉姆，

>>行为： 未收到寡妇10（建造号10240）"摇动"。事件

>>behavior:  Widows 10 (Build no 10240) is not received "Shaken" event

实际上，Windows 10 Mobile还没有发布，所以我不知道这是否适用于RTM windows10 SDK。无论如何，这在Windows Mobile 10149上不起作用。

Actually, the Windows 10 Mobile has not been released, so I don't know if this should work for the RTM windows10 SDK. Anyway, this don't work on Windows Mobile 10149.

作为一种解决方法，您可以处理
Accelerometer.ReadingChanged 事件并分析数据更改频率以确定设备是否在抖动：

As a workaround, you can handle Accelerometer.ReadingChanged event and analysis the data change frequency to determine if the device is shaking:

Accelerometer _accelerometer = Accelerometer.GetDefault();

private async void ReadingChanged(object sender, AccelerometerReadingChangedEventArgs e)
{
            await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
            {
                AccelerometerReading reading = _accelerometer.GetCurrentReading();
                if (reading != null)
                {
                    ScenarioOutput_X.Text = String.Format("{0,5:0.00}", reading.AccelerationX);
                    ScenarioOutput_Y.Text = String.Format("{0,5:0.00}", reading.AccelerationY);
                    ScenarioOutput_Z.Text = String.Format("{0,5:0.00}", reading.AccelerationZ);
                }

            });
}

private void Button_Click(object sender, RoutedEventArgs e)
{
            if (_accelerometer != null)
            {
                // Establish the report interval
                uint minReportInterval = _accelerometer.MinimumReportInterval;
                uint reportInterval = minReportInterval > 16 ? minReportInterval : 16;
                _accelerometer.ReportInterval = reportInterval;

                // Assign an event handler for the reading-changed event
                _accelerometer.ReadingChanged += new TypedEventHandler<Accelerometer, AccelerometerReadingChangedEventArgs>(ReadingChanged);

            }
            else
            {
                Debug.WriteLine("No accelerometer found");
            }
}
