Xamarin.android如何添加snackbar回调

<package id="Xamarin.Android.Support.Design" version="版本号" targetFramework="目标框架" />

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/coordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <!-- 布局内容 -->
    
</android.support.design.widget.CoordinatorLayout>

CoordinatorLayout coordinatorLayout = FindViewById<CoordinatorLayout>(Resource.Id.coordinatorLayout);
Snackbar snackbar = Snackbar.Make(coordinatorLayout, "消息内容", Snackbar.LengthLong);

snackbar.SetAction("按钮文本", (view) =>
{
    // 按钮点击事件处理程序
});

snackbar.SetCallback(new SnackbarCallback());

public class SnackbarCallback : Snackbar.Callback
{
    public override void OnDismissed(Snackbar snackbar, int dismissType)
    {
        // Snackbar隐藏事件处理逻辑
    }
}
