Here, you’ll find how to make components' stylization on Android’s projects.


Inside Beagle’s library, there is a DesignSystem class that can be used to personalize the components used on your application.

This class also can map application’s local resources so we can refer to BFF when you build a Server-Driven screen.

Beside the images, Beagle’s Design System can customize:

  • the appearance of the texts;
  • the style of the input components;
  • the style of the buttons;
  • the style of the toolbars and
  • tabViews.

Customized attributes


The text components for Beagle Android are totally customizable. To make this change, follow the example below:

<!-- Custom style for textual components. -->
    <style name="CustomText" parent="Widget.AppCompat.TextView">
        <item name="android:textColor">#000000</item>
        <item name="android:textSize">20sp</item>
        <item name="android:textStyle">bold</item>


The input components in Beagle Android are also fully customizable. To make any changes, follow the example below:

<!-- Custom style for textual components. -->
    <style name="CustomInput" parent="Widget.AppCompat.EditText">
        <item name="android:textColor">@color/colorBlack</item>
        <item name="android:background">@drawable/text_input_background</item>


Like the texts and inputs, the buttons on Beagle Android are fully customizable. To make any changes, follow the example below:

<!-- Custom style for Button components. -->
    <style name="CustomButton" parent="Widget.AppCompat.Button">
        <item name="android:textColor">#000000</item>
        <item name="android:textSize">18sp</item>
        <item name="android:textAllCaps">false</item>
        <item name="android:background">?attr/selectableItemBackground</item>


Inside Beagle’s library for Android, the tool bar is part of NavigationBar’s class. To make it properly work on BeagleActivity, you need to inform Beagle which bar will be used on your application.

The bar customization can be done in the moment that it passes through Beagle. Besides these attributes, Toolbar has other four exclusive ones:

  1. backgroundColor: defines the Tool Bar’s background color.
  2. navigationIcon: receives a drawable and attributes it to a navigation bar icon on the tool bar.
  3. titleTextAppearance: receives a text style to personalize a tool bar’s title.
  4. centerTitle: when activated, centralize the tool bar’s title.
<!-- Custom style for Toolbar components. -->
    <style name="CustomToolbar" parent="Widget.AppCompat.Toolbar">
        <item name="backgroundColor">@color/colorPrimaryDark</item>
        <item name="navigationIcon">?attr/homeAsUpIndicator</item>
        <item name="titleTextAppearance">@style/CustomTitleToolbar</item>
        <item name="centerTitle">true</item>
    <style name="CustomTitleToolbar" parent="TextAppearance.AppCompat">
        <item name="android:textColor">@color/colorPrimary</item>
        <item name="android:textSize">20sp</item>
        <item name="android:textStyle">bold</item>


Beagle’s TabView component represents the Android’s TabLayout and all its visual structure tha can be stylized with the following attributes:

  1. tabSelectedTextColor: attributes a different color to a selected tab’s text.
  2. tabTextColor: attributes a text color to all tabs, which means not selected tabs.
  3. tabBackground: receives a drawable and attributes it to TabView’s background.
  4. tabIndicatorColor: attributes a color to a selection’s indicator of one tab.
  5. tabIconTint: receives a drawable to define icons' colors, being selected or not.
<!-- Custom style for TabLayout components. -->
    <style name="CustomTab" parent="Widget.Design.TabLayout">
        <item name="tabSelectedTextColor">@color/colorWhite</item>
        <item name="tabTextColor">@color/colorBlack</item>
        <item name="tabBackground">@color/colorPrimaryDark</item>
        <item name="tabIndicatorColor">@color/colorWhite</item>
        <item name="tabIconTint">@color/selector_icon_color</item>

To manage all the selected tabs, we recommend you to use a selector for the tabIconTint attribute, as in the example below:

<selector xmlns:android="">
    <item android:color="@android:color/white" android:state_selected="true" />
    <item android:color="@android:color/black" />
