有没有办法防止 Xamarin Forms 滚动视图在打开选择器控件时自动滚动到最后编辑的条目？

Question

I have a setup similar to this:

  <ScrollView>
    <StackLayout>    
      <Entry/>
      <Picker/>
      <Entry/>
      <Entry/>
      <Entry/>
      <Picker/>
      <Picker/>
      <Entry/>
      <Entry/>
      <Entry/>
    </StackLayout>

  </ScrollView>

Where the Entry and Picker controls are dynamically created and modified. The problem is that if I type into an Entry and then open one of the Picker controls, the ScrollView scrolls to where the previously edited Entry is in view. It was getting focus, but I prevented the focus from shifting, yet the ScrollView scrolls and I can't seem to prevent it.

I did something similar to Is it possible to stop the first Entry getting Focus in a ScrollView in Xamarin Forms to fix the related issue in UWP, but that solution is not applicable to iOS and Android.

Set the name of StackLayout . Foreach the elements in 'StackLayout' and reset the focus.

 private void Picker_Focused(object sender, FocusEventArgs e)
    {
        foreach (var item in stackLayout.Children)
        {
            if (sender!=item)
            {
                item.Unfocus();                   
            }              
        }
    }
