I have started learning Android Studio and I am trying to change my button's background, but it is just not working. Here is my code:
<Button
android:layout_width="300dp"
android:layout_height="200dp"
android:text="salam"
android:textSize="30sp"
android:textColor="#ffccee"
android:background="#ffffff"
/>
The background color stays the same after I change it.
