CodePudding user response：

You could use the FocusSearchDirection.Right to make the textview start scrolling from right to left.

      <HorizontalScrollView
    android:id="@ id/ScrollView"
    android:layoutDirection="rtl"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#007b12"
    android:scrollbars="none">
    <TextView
        android:text="zzzzzzzzzzzzzzztfytytytytytytytytytytytytgjjjjjjjjjjjjjjjjjjjjjiylhnhjk7fj"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@ id/textView1"
        android:layout_marginTop="10dp"
        android:textSize="60sp"
        android:textColor="@android:color/white"
        android:maxLines="1"
        android:scrollbars="none"
        android:layout_gravity="right"/>
</HorizontalScrollView>

Code behind:

   var scrollview = FindViewById<HorizontalScrollView>(Resource.Id.ScrollView);
        scrollview.PostDelayed(new Runnable(()=>
        {
            scrollview.FullScroll(FocusSearchDirection.Right);
        }), 100L);
