WPF-GridView设置列宽按比例分配

1. 将ListView包裹在一个父Grid中
2. 写一个与ListView平行的Grid，设置该Grid的列数与ListView中GridView的列数相同，将该Grid各列设置列宽按比例分配
3. 将ListView中GridView的各列的Width绑定上述Grid的ActualWidth
4. 这样，通过设置上述Grid各列的比例，就对应设置了ListView中GridView的各列的比例

<Grid Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="3*" />
            <ColumnDefinition Width="2*" />
            <ColumnDefinition Width="8*"/>
            <ColumnDefinition Width="5*"/>
            <ColumnDefinition Width="5*"/>
        </Grid.ColumnDefinitions>
        <Grid Grid.Column="0" x:Name="HumidifyEventLogCol0"/>
        <Grid Grid.Column="1" x:Name="HumidifyEventLogCol1"/>
        <Grid Grid.Column="2" x:Name="HumidifyEventLogCol2"/>
        <Grid Grid.Column="3" x:Name="HumidifyEventLogCol3"/>
        <Grid Grid.Column="3" x:Name="HumidifyEventLogCol4"/>
    </Grid>

    <ListView Name="HumidifyEventLog" Style="{StaticResource ListViewStyle}" ItemContainerStyle="{StaticResource ResourceKey=ListViewItemStyle}">
        <ListView.View>
            <GridView ColumnHeaderContainerStyle="{StaticResource GridViewColumnHeaderStyle}">
                <GridViewColumn Header="设备" Width="{Binding ElementName=HumidifyEventLogCol0,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=Source, Converter={StaticResource ChamberNameEnToCn}}"/>
                <GridViewColumn Header="故障ID" Width="{Binding ElementName=HumidifyEventLogCol1,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=Code}"/>
                <GridViewColumn Header="故障描述" Width="{Binding ElementName=HumidifyEventLogCol2,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=Remark}"/>
                <GridViewColumn Header="故障开始时间" Width="{Binding ElementName=HumidifyEventLogCol3,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=StartTime}"/>
                <GridViewColumn Header="故障结束时间" Width="{Binding ElementName=HumidifyEventLogCol4,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=EndTime}"/>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>
