Xamarin.Essentials: Haptic Feedback

  • Artikkeli

The HapticFeedback class lets you control haptic feedback on device.

Get started

To start using this API, read the getting started guide for Xamarin.Essentials to ensure the library is properly installed and set up in your projects.

To access the HapticFeedback functionality the following platform specific setup is required.

The Vibrate permission is required and must be configured in the Android project. This can be added in the following ways:

Open the AssemblyInfo.cs file under the Properties folder and add:

[assembly: UsesPermission(Android.Manifest.Permission.Vibrate)]

OR Update Android Manifest:

Open the AndroidManifest.xml file under the Properties folder and add the following inside of the manifest node.

<uses-permission android:name="android.permission.VIBRATE" />

Or right click on the Android project and open the project's properties. Under Android Manifest find the Required permissions: area and check the VIBRATE permission. This will automatically update the AndroidManifest.xml file.

Using Haptic Feedback

Add a reference to Xamarin.Essentials in your class:

using Xamarin.Essentials;

The Haptic Feedback functionality can be performed with a Click or LongPress feedback type.

try
{
    // Perform click feedback
    HapticFeedback.Perform(HapticFeedbackType.Click);

    // Or use long press    
    HapticFeedback.Perform(HapticFeedbackType.LongPress);
}
catch (FeatureNotSupportedException ex)
{
    // Feature not supported on device
}
catch (Exception ex)
{
    // Other error has occurred.
}
