Android Studio 3.2.1 Here my layout:

<com.google.android.material.button.MaterialButton
                android:id="@+id/bittrexJsonViewButton"
                android:layout_width="0dp"
                android:layout_height="@dimen/min_height"
                android:layout_marginStart="@dimen/half_default_margin"
                android:layout_marginEnd="@dimen/half_default_margin"
                android:text="@string/json_view"
                app:layout_constraintBottom_toBottomOf="@+id/binanceJsonViewButton"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toEndOf="@+id/binanceJsonViewButton"
                app:layout_constraintTop_toTopOf="@+id/binanceJsonViewButton" />

to change MaterialButton's background I change colorAccent in styles.xml

<item name="colorAccent">@color/colorAccent</item>

Nice. It's work.

But the problem is: I do not want to change colorAccent. I want to use background's color for MaterialButton's different from colorAccent

Attribute:

android:background="#aabbcc"

not help.

1st Solution

You can use app:backgroundTint to change back ground color of MaterialButton

<com.google.android.material.button.MaterialButton
                android:id="@+id/bittrexJsonViewButton"
                android:layout_width="0dp"
                android:layout_height="@dimen/min_height"
                android:layout_marginStart="@dimen/half_default_margin"
                android:layout_marginEnd="@dimen/half_default_margin"
                app:backgroundTint="@android:color/holo_orange_dark"
                android:text="@string/json_view"
                app:layout_constraintBottom_toBottomOf="@+id/binanceJsonViewButton"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toEndOf="@+id/binanceJsonViewButton"
                app:layout_constraintTop_toTopOf="@+id/binanceJsonViewButton" />

2nd Solution

MaterialButton uses colorPrimary as background when button is in active state and colorOnSurface when disabled. So, you can define it in your theme and apply it on material buttons
