<ListView HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" IsItemClickEnabled="False" Background="AliceBlue">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid Orientation="Horizontal" HorizontalAlignment="Stretch" MaximumRowsOrColumns="2"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListViewItem Background="Aqua" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch">
<TextBlock Text="1111"/>
</ListViewItem>
<ListViewItem Background="Aquamarine" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch">
<TextBlock Text="2222"/>
</ListViewItem>
<ListViewItem>
<TextBlock Text="3333"/>
</ListViewItem>
<ListViewItem>
<TextBlock Text="44444"/>
</ListViewItem>
</ListView>
现在listviewitem的宽度为 ListViewItem里面的内容宽度
要怎样才能实现多列平分一整行,即宽度就像Grid的*,而不是ListViewItem里面的内容宽度
