今天遇到的问题：

方法1：设置GridViewColumn的ActualWidth

 <ListView >
            <ListView.View>
                <GridView >
                    <GridViewColumn Header="名称"   Width="200" x:Name="column">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Name}" TextAlignment="Center" MinWidth="{Binding Path=ActualWidth,ElementName=column}"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="接收"  Width="120" x:Name="sss">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <Border  MinWidth="{Binding Path=ActualWidth,ElementName=sss}">
                                    <CheckBox IsChecked="{Binding IsReceive}" HorizontalAlignment="Center"/>
                                </Border>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>

注意修改CheckBox居中的时候，需要把他套在Border里，直接写在CheckBox上话没效果。

方法2：设置Style，推荐。

        <Style x:Key="ListViewItemStyle" TargetType="{x:Type ListViewItem}">
            <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
        </Style>

再修改需要居中的控件HorizontalAlignment=“Center”

<ListView ItemContainerStyle="{DynamicResource ListViewItemStyle}">
            <ListView.View>
                <GridView >
                    <GridViewColumn Header="名称"   Width="200">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding Name}"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="接收"  Width="120">
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <CheckBox IsChecked="{Binding IsReceive}" HorizontalAlignment="Center"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                    <GridViewColumn Header="拒绝"  Width="120" >
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <CheckBox IsChecked="{Binding IsRefuse}" HorizontalAlignment="Center"/>
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>
                </GridView>
            </ListView.View>
        </ListView>
