How to stretch a listviewitem into a listview

developers.

I am trying to stretch a list item in horizontal orientation. I am doing reset ItemContainerStyle and horizontal alignment is strech. Here is all the code in MainPage.xaml.

<Grid x:Name="rootGrid"
      HorizontalAlignment="Stretch"
      MinWidth="320"
      MaxWidth="480"
      Width="Auto">
    <ListView x:Name="infoFlowListView" 
              MinWidth="320"
              MaxWidth="480"
              Width="Auto"
              HorizontalAlignment="Stretch">
        <ListView.ItemTemplate>
            <DataTemplate>
                <local:MyUserControl1 MinWidth="300" HorizontalAlignment="Stretch"></local:MyUserControl1>
            </DataTemplate>
        </ListView.ItemTemplate>
        <ListView.ItemContainerStyle>
            <Style TargetType="ListViewItem">
                <Setter Property="HorizontalAlignment" Value="Stretch"></Setter>
            </Style>
        </ListView.ItemContainerStyle>
    </ListView>
</Grid>

      

        
        
        
      

    

Here is all the code in MainPage.xaml.cs

public MainPage()
    {
        var items = new List<MyUserControl1>();
        for (int i = 0; i < 50; i++)
        {
            items.Add(new MyUserControl1());
        }
        this.InitializeComponent();
        infoFlowListView.ItemsSource = items;
    }

I am testing this code on a 6inch emulator, and I am adding a screenshot of this example.

And mobile emulators don't have the same result. Here are some screenshots of the emulator. 4inch screenshot of example The right side of these screenshots is different.
