failed to find '@attr/TextAppearanceButton' in current theme

Question

I want to add Extended floating action button to my android project app but got an error saying failed to find @attr/TextAppearanceButton in current theme. I have implemented material dependency in build.grade module. I am new to Android Development. Please I need a help 🙏🏾.

Answer 1

change your styles.xml to like below

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

Answer 2

I was also facing the issue of rendering xml files after updating my android studio to DOPLPHIN.

In your xml, add android:theme="@style/YOUR_MATERIAL_THEME" to your parent layout and all rendering issues will be gone.

                   OR

In your manifest file under <application add android:theme="@style/YOUR_MATERIAL_THEME"

I hope this fixes your issue.
