添加了Xamarin.Forms条目文本，但未显示

启动应用程序时，我正在制作Pin验证程序。这是我的代码：

   <ContentPage.Content>


        <StackLayout Spacing="10" VerticalOptions="Center" Margin="10,0,10,0" >
            <Grid x:Name="LayoutRoot">
                <Grid.RowDefinitions>
                    <RowDefinition Height="1.3*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="0.5*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />
                    <RowDefinition Height="*" />

                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="2*" />
                    <ColumnDefinition Width="2*" />
                    <ColumnDefinition Width="2*" />
                    <ColumnDefinition Width="*" />

                </Grid.ColumnDefinitions>

                <Grid.RowSpacing>
                    <OnPlatform x:TypeArguments="x:Double" Android="20"  iOS="20"  />
                </Grid.RowSpacing>

                <Grid.ColumnSpacing>
                    <OnPlatform x:TypeArguments="x:Double" Android="20"  iOS="20"  />
                </Grid.ColumnSpacing>

                <Frame BorderColor="#006BE6"  BackgroundColor="WhiteSmoke"  Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="3" >
                    <Entry TextColor="#006BE6"  FontSize="48" IsPassword="True" x:Name="Output" Text="{Binding Pin}"  HorizontalOptions="Center" VerticalOptions="Center" IsReadOnly="True">
                        <Entry.Behaviors>
                            <behaviors:EntryLengthValidatorBehavior MaxLength="4" />
                        </Entry.Behaviors>
                    </Entry>
                </Frame>



                <Button TextColor="#006BE6" Text="1" Grid.Row="3" Grid.Column="1" Command="{Binding LoadNumberCommand}" CommandParameter="1" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"    />

                <Button TextColor="#006BE6" Text="2" Grid.Row="3" Grid.Column="2" Command="{Binding LoadNumberCommand}" CommandParameter="2" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>

                <Button TextColor="#006BE6"  Text="4" Grid.Row="4" Grid.Column="1" Command="{Binding LoadNumberCommand}" CommandParameter="4" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>
                <Button TextColor="#006BE6"  Text="5" Grid.Row="4" Grid.Column="2" Command="{Binding LoadNumberCommand}" CommandParameter="5" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>

                <Button TextColor="#006BE6"  Text="7" Grid.Row="5" Grid.Column="1" Command="{Binding LoadNumberCommand}" CommandParameter="7" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>
                <Button TextColor="#006BE6" Text="8" Grid.Row="5" Grid.Column="2" Command="{Binding LoadNumberCommand}" CommandParameter="8" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>

                <Button TextColor="#006BE6" Text="C" Grid.Row="6" Grid.Column="1" Command="{Binding LoadNumberCommand}" CommandParameter="C"  BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>
                <Button TextColor="#006BE6" Text="0" Grid.Row="6" Grid.Column="2" Command="{Binding LoadNumberCommand}" CommandParameter="0" BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>
                <Button TextColor="#006BE6" Text="OK" Grid.Row="6" Grid.Column="3" Command="{Binding LoadNumberCommand}" CommandParameter="OK"  BorderColor="#006BE6" BorderWidth="1" BackgroundColor="WhiteSmoke"/>

            </Grid>
        </StackLayout>
    </ContentPage.Content>

指挥部呢

LoadNumberCommand = new Command(execute: async (value) => await ExecutePinElement(value));

将条目的IsReadOnlyproperty设置为false

或

---

将水平选项更改为FillAndExpand并添加HorizontalTextAlignment=Center

您能更具体一点吗？是未显示的文本还是条目本身？绑定Pin正在工作。在Pin中，我得到了我添加的数字，但数字或密码****没有显示我将用截图编辑的文本。你能显示EntryLengthValidatorBehavioryour吗？在输入框FillandExp中添加grid.row=1和grid.Column=1 grid.ColumnSpan=3并解决了我的问题，我是居中的，没有显示所有文本，谢谢你乐于帮助=

LoadNumberCommand = new Command(execute: async (value) => await ExecutePinElement(value));
