Android studio button fixed color can't be changed-CodePudding

can someone help me I'm using a button in android ,I'm unable to change the button color , this is my xml code :

  <Button
    android:id="@ id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button"
    tools:layout_editor_absoluteX="133dp"
    tools:layout_editor_absoluteY="584dp" />

CodePudding user response：

Use the attribute android:background. For example:

<Button
    android:id="@ id/button3"
    <!-- ADD THE LINE BELOW -->
    android:background="@color/black" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button"
    tools:layout_editor_absoluteX="133dp"
    tools:layout_editor_absoluteY="584dp" />

If you can't see the color you want, please add it to the colors.xml file stored in the values folder. This is an example of a colors.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
   <color name="black">#333333</color>
</resources>

You should already have this file, if not, add it.

You can use Material Button and it's won't affect ripple and elevation of Button

 <com.google.android.material.button.MaterialButton
            android:layout_width="wrap_content"
            app:backgroundTint=""ff0000"
            android:text="Hello World"
            android:layout_height="wrap_content" />

Have a look in your themes.xml file . Change to android:theme="@style/Theme.AppCompat.NoActionBar"
