You can do it by adding this statement in styles
<item name="android:navigationBarColor">@color/theme_color</item>
or this in the main java
window.setNavigationBarColor(@ColorInt int color);
mDrawerLayout.setBackgroundResource(int);
if you are using NavigationView the choose give this option
android:background="@color/color_navigation_list_background"
