Android Button background color not changing

Question

In this android project im creating a default button style. my styles.xml

<!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">     <item name="android:buttonStyle">@style/ButtonStlye123</item> </style>  <style name="ButtonStlye123" parent="android:style/Widget.Button">     <item name="android:textSize">19dp</item>     <item name="android:layout_margin">8dp</item>     <item name="android:padding">8dp</item>     <item name="android:textColor">@color/ColorDivider</item>      <item name="android:background">@color/ColorAccent</item> </style> 

my button in a fragment.

<Button     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="@string/btnLogin"     android:id="@+id/btn_login"     android:layout_alignParentBottom="true"     android:layout_alignParentLeft="true"     android:layout_alignParentStart="true"     android:layout_alignParentRight="true"     android:layout_alignParentEnd="true"     android:theme="@style/ButtonStlye123"     android:onClick="login" /> 

In the preview in android studio it looks exactly like I want, but when I run the app on my device the background color is gray ("default button color"). If i change the text color in my styles.xml like:

<item name="android:textColor">@color/ColorPrimary</item> 

it changes (also on my device) so the custom style is loading, i tryd different colors (that worked for the text) for the button but it wont change.

Why isnt my background color loading?

Try use AppCompactButton instead of

<Button 

use

<androidx.appcompat.widget.AppCompatButton 

that will do the trick

Found out that the above will not work on earlier Android versions. For materiel design Button use

app:backgroundTint="@color/green"
