Android Design Patterns, Medium, Medium

The first one works. The other two don't but stiff leave there for reference purposes.

Create this theme in res/values/styles.xml

<style name="RewardRedeemButtonTheme" parent="ThemeOverlay.AppCompat.Light">
        <item name="colorAccent">@color/white_tint_1</item>
</style>

Apply it to the button like this

    <android.support.v7.widget.AppCompatButton
        android:id="@+id/item_reward_redeem_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/text_redeem"
        android:textAppearance="@style/TextAppearance.AppCompat.Button"
        android:textColor="@color/black_tint_3"
        android:textSize="12sp"
        style="@style/Widget.AppCompat.Button.Colored" //need this for press effect
        android:theme="@style/RewardRedeemButtonTheme" //this will change the background
/>
