如何在Xamarin android中放置循环加载动画

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:drawable="@drawable/frame1"
        android:duration="100" />
    <item
        android:drawable="@drawable/frame2"
        android:duration="100" />
    <!-- Add more frames here -->
</animation-list>

<ImageView
    android:id="@+id/loadingImageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/loading_animation" />

ImageView loadingImageView = FindViewById<ImageView>(Resource.Id.loadingImageView);
loadingImageView.SetImageResource(Resource.Drawable.loading_animation);
AnimationDrawable loadingAnimation = (AnimationDrawable)loadingImageView.Drawable;
loadingAnimation.Start();
