I am using the Snackbar
provided by the Material Components Library .
I am looking for a way to customize the style of the ACTION Button.
I know that the Snackbar
uses this layout ( layout.mtrl_layout_snackbar_include
) with this Button
:
<Button
android:id="@+id/snackbar_action"
but I am trying to avoid to use some workarounds that can stop to work with the next releases.
In particular I would like to use a OutlinedButton
style and a custom shape as an arrow .
With the version 1.1.0 of the Material Components Library you can define in your app theme the style used by the action button within a Snackbar
using the snackbarButtonStyle
attribute.
<style name="AppTheme" parent="Theme.MaterialComponents.*">
<!-- Style to use for action button within a Snackbar in this theme. -->
<item name="snackbarButtonStyle">@style/Widget.MaterialComponents.Button.TextButton.Snackbar</item>
....
</style>
You can customize the style using:
<style name="Custom.MaterialComponents.Button.TextButton.Snackbar" parent="@style/Widget.MaterialComponents.Button.TextButton.Snackbar">
<item name="strokeColor">@color/...</item>
<item name="strokeWidth">1dp</item>
....
<item name="shapeAppearanceOverlay">@style/Snackbar.ShapeAppearanceOverlay.Arrow</item>
</style>
With the shapeAppearanceOverlay
you can customize the shape:
<style name="Snackbar.ShapeAppearanceOverlay.Button.Arrow" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerFamilyTopRight">cut</item>
<item name="cornerFamilyBottomRight">cut</item>
<item name="cornerSizeTopLeft">0dp</item>
<item name="cornerSizeBottomLeft">0dp</item>
<item name="cornerSizeTopRight">50%</item>
<item name="cornerSizeBottomRight">50%</item>
</style>
You can obtain an OutlinedButton
style in same way. Just define a custom style with:
<style name="Outlined.MaterialComponents.Button.TextButton.Snackbar" parent="@style/Widget.MaterialComponents.Button.OutlinedButton">
<item name="strokeColor">@color/...</item>
<item name="strokeWidth">1dp</item>
<item name="android:textColor">@color/...</item>
</style>
