item selected color in android BottomNavigationView

Question

I refer this. Schedules Activity is appeared when I click Schedules, but first item color (Favorites) is always selected. It doesn't change Schedules item color from Favorites item color. And also, third item (Music). I use android:state_checked NOT android:state_enabled." If working with startActivity, it doesn't change Schedules item color from Favorites item color. If not, it change color. How to solve this color select problems.

activity_main.xml

app:itemIconTint="@drawable/nav_item_color_state"
app:itemTextColor="@drawable/nav_item_color_state"
app:menu="@menu/bottom_navigation_main"

@drawable/nav_item_color_state

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/white" android:state_enabled="true" />
    <item android:color="@color/colorPrimaryDark" android:state_enabled="false" />
</selector>

Answer 1

create a color directory in res folder and create your xml file for customize your bottom navigation items:

res/color/bottom_nav_color.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
     <item android:state_checked="true" android:color="@color/your_color" />
     <item android:state_checked="false" android:color="@color/your_color"/>
</selector>

and in your BottomNavigationView set app:itemTextColor and app:itemIconTint values to @color/bottom_nav_color

<android.support.design.widget.BottomNavigationView
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   android:id="@+id/main_navigation"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:layout_alignParentBottom="true"
   android:background="@color/actionBarColor"
   app:menu="@menu/my_navigation_items"
   app:itemTextColor="@color/bottom_nav_color"
   app:itemIconTint="@color/bottom_nav_color"/>
