I can’t change the button color (xml) in Android Studio

Question

I can’t change the color of the button in Android Studio. Whenever I create a button by XML it takes the primary color that is set in Themes.xlm and when I set a color, the code does not error but the button does not change color. I did not find anywhere, how should I proceed?

This is Luiz Felipe, baby?

So, there are some ways to change the button color, and if it’s getting the color of your theme, it’s probably the colorAccent.

Some of the ways are:

Create a new style and assign to the button (recommended for better standardization):

 <style name="Button.White" parent="ThemeOverlay.AppCompat">
        <item name="colorAccent">@android:color/white</item>
    </style>

That on the button would be:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/Button.White"
    />

You can also try the backgroundTint for Apis >= 21:

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:backgroundTint="@android:color/white"
    />

Also look for how to set these values programmatically.

I hope I’ve helped.
