Can you change the textcolor of all the tools in your project?-CodePudding

can you change the text color of all your text inside your project? I mean not by binding or what, just by setting the default color or do I really need to change the property of each label/entry/button etc...?

CodePudding user response：

In Xamarin you can create a global style. From the documentation:

Styles can be made available globally by adding them to the application's resource dictionary. This helps to avoid duplication of styles across pages or controls.

CodePudding user response：

One way is to use the style and target to the label/entry/button etc.

<Style TargetType="Label">
<Setter Property="TextColor" Value="Black" />
</Style>

For more details, refer to: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/styles/xaml/

Another way is to set the color as resource.

Set the resource:

 <Application.Resources>
    <!-- Colors -->
    <Color x:Key="NormalTextColor">Black</Color>
</Application.Resources>

Usage:

   <Label Text="Hello"
                   TextColor="{StaticResource NormalTextColor}"
                   FontAttributes="Bold" />

For more details, refer to: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/xaml/resource-dictionaries

Like TheTanic answer. For example:

In App.xaml a Style for Label with the name BLabel.

<Style x:Key="BLabel" TargetType="Label">
    <Setter Property="TextColor"  Value="#A7ADB1" />
    <Setter Property="HorizontalOptions" Value="Start" />
    <Setter Property="VerticalOptions" Value="Center" />
</Style>

You can use it like this , in MainPage.xaml.

 <Label
   Grid.Row="4"
   Grid.Column="1"
   Style="{StaticResource BLabel}"
   Text="BB 3" />

But there is more you can add to this like:

 <Setter Property="WidthRequest" Value="150" />
    <Setter Property="HeightRequest" Value="40" />
    <Setter Property="FontSize" Value="Small" />
    <Setter Property="BorderWidth" Value="1" />
    <Setter Property="BackgroundColor" Value="Red" />
    <Setter Property="HorizontalOptions" Value="Center" />
    <Setter Property="TextTransform" Value="None" />

and more ....

Not only for labels but Buttons etc.

This is an example for StaticResource but you can also use DynamicResource to change color's etc.
