如何在android xamarin中边拍照边EnableShutterSound

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

Camera camera;
Camera.Parameters parameters;

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);

    // 获取相机实例
    camera = Camera.Open();

    // 获取相机参数
    parameters = camera.GetParameters();
}

parameters.Sounds = true;
camera.SetParameters(parameters);

camera.TakePicture(null, null, new PictureCallback());

private class PictureCallback : Java.Lang.Object, Camera.IPictureCallback
{
    public void OnPictureTaken(byte[] data, Camera camera)
    {
        // 处理拍照结果
    }
}
