In my app I need to change the bottom navigation bar color. I watched many post but cant find with the solution. I am using appCompat library.
v21/styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:windowBackground">@drawable/bgpreview</item>
<item name="android:colorPrimary">@color/MyColor</item>
<item name="android:colorPrimaryDark">@color/MyColor</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:textColorPrimary">@color/MyColor</item>
<item name="colorAccent">@color/MyColor</item>
<!-- darker variant for the status bar and contextual app bars -->
<item name="android:windowContentTransitions">true</item>
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>
<item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
<item name="android:windowSharedElementExitTransition">@android:transition/move</item>
<item name="windowActionBar">false</item>
<item name="android:textAllCaps">false</item>
</style>
It can be done inside styles.xml using
<item name="android:navigationBarColor">@color/theme_color</item>
or
window.setNavigationBarColor(@ColorInt int color)
http://developer.android.com/reference/android/view/Window.html#setNavigationBarColor(int)
Note that the method was introduced in Android Lollipop and won't work on API version < 21.
The second method (works on KitKat) is to set windowTranslucentNavigation to true in the manifest and place a colored view beneath the navigation bar.
