Android style dosen't work

I am trying to add a specific style for a button, the issue is that it's works in themes.xml when I write this :

themes.xml

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<item name="colorControlHighlight">@color/background</item>
<item name="colorButtonNormal">@color/white</item>
</style>


mylayout.xml

<Button
android:id="@+id/play"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:gravity="center"
android:text="Play"
android:textColor="@color/guillotine_background"
android:textSize="25dp"
android:textStyle="bold"/>


but I don't get the same result when I use this :

styles.xml

<style name="MyColorButton" parent="AppTheme">
<item name="colorControlHighlight">@color/background</item>
<item name="colorButtonNormal">@color/white</item>
</style>


I added this line to the button tag in mylayout.xml

mylayout.xml

style="@style/MyColorButton"


Isn't that must return the same result ?

Answer

colorControlHighlight and colorButtonNormal are theme attributes. They are for styles that are used as themes for an Activity. They are not attributes of a Button. If you want to use it on the Button but not the whole Activity, use android:theme attribute instead:

<Button
    android:theme="@style/MyColorButton"
    ... />
