Bottom Navigation Icon color change

问题

I am using a BottomNavigation this when i try to change bottom navigation icon colors with black background its not change color.

 bottomNavigation.setAccentColor(Color.parseColor("#FFE4770A"));
 bottomNavigation.setInactiveColor(Color.WHITE);
 bottomNavigation.setBackgroundColor(Color.BLACK);

But when i tried it with background it changes icon color.

 bottomNavigation.setAccentColor(Color.parseColor("#FFE4770A"));
 bottomNavigation.setInactiveColor(Color.WHITE);

How do fix it? it changes icon color with color background.

回答1:

According to the documentation of ahbottomnavigation repo, setBackgroundColor() will override the accent colors for icons.

Replace setBackgroundColor() with setDefaultBackgroundColor() :

 bottomNavigation.setDefaultBackgroundColor(Color.BLACK);

I have an another solution, if you wanna try in XML,

app:itemBackground="@color/white" --> This can be use to bottom bar color app:itemIconTint="@color/blue" --> This can be used to change icons color app:itemTextColor="@color/blue" --> This can be used to change icon bottom text color

XML source code shown as below

<android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="0dp"
        android:layout_marginStart="0dp"
        app:itemBackground="@color/white"
        app:itemIconTint="@color/blue" 
        app:itemTextColor="@color/blue" 
        app:menu="@menu/navigation" />
