You can change the background or ripple color of each Tab like this         set ripple color for each tab     for int n   0  n  lt  mTabLayout getTabCount    n              View tab     ViewGroup mTabLayout getChildAt 0   getChildAt n            if tab    null  amp  amp  tab getBackground   instanceof RippleDrawable               RippleDrawable rippleDrawable    RippleDrawable tab getBackground                if  rippleDrawable    null                    rippleDrawable setColor ColorStateList valueOf rippleColor

One of the ways I could find is using the tab indicator like this   lt com google android material tabs TabLayout     android layout width  quot match parent quot      android layout height  quot wrap content quot      app tabBackground  quot  color normal unselected color quot      app tabIndicatorColor  quot  color selected color quot      app tabIndicatorGravity  quot center quot      app tabIndicatorHeight  quot 150dp quot      app tabSelectedTextColor  quot  color selected text color quot      app tabTextColor  quot  color unselected text color quot  gt             tab items here         lt  com google android material tabs TabLayout gt   Trick is to   Make the tab indicator to align in center Make the indicator height sufficiently large so that it covers the whole tab  This also takes care of the smooth animation while switching tabs

What finally worked for me is similar to what      DJ suggested  but the tabBackground should be in the layout file and not inside the style  so it looks like   res layout somefile xml    lt android support design widget TabLayout              app tabBackground   drawable tab color selector                gt    and the selector res drawable tab color selector xml    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android drawable   color tab background selected  android state selected  true   gt       lt item android drawable   color tab background unselected   gt   lt  selector gt

Since ViewPager is tending to be replaced by ViewPager2 and we will need to migrate to it  A quick work around using Java would be something like this      final List lt String gt  colors   new ArrayList lt String gt                           add  quot  FF0000 quot                add  quot  800000 quot                add  quot  FFFF00 quot                               ViewPager2 viewPager   findViewById R id viewPager       ViewPagerAdapter adapter   new ViewPagerAdapter your data structure       viewPager setAdapter adapter        final TabLayout tabs   findViewById R id tabs        tabs addOnTabSelectedListener new TabLayout OnTabSelectedListener              Override         public void onTabSelected TabLayout Tab tab                tab view setAlpha  float  0 5                       Override         public void onTabUnselected TabLayout Tab tab                tab view setAlpha 1                       Override         public void onTabReselected TabLayout Tab tab                            TabLayoutMediator mediator   new TabLayoutMediator tabs  viewPager  new TabLayoutMediator TabConfigurationStrategy              Override         public void onConfigureTab  NonNull TabLayout Tab tab  int position                tab setText  quot Tab quot    position                                               With this feature the TabIndicator color is ignored                 or covered by the new color ex  if alpha channel is changed the indicator can be seen through                             tab view setBackgroundColor Color parseColor colors get position       You can use your HEX string color                        mediator attach

After some messing around this is how I got the desired look  at least in the emulator  and it keeps the ripple effect      lt com google android material tabs TabLayout     android id    id tabs      android layout width  match parent      android layout height  wrap content      app tabBackground   drawable tab selector      app tabIconTint   drawable tab selector      app tabIconTintMode  src atop      app tabTextColor   drawable tab selector    gt    And the  drawable tab selector    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android color   color colorPrimary  android drawable   color colorPrimaryDark  android state selected  true    gt       lt item android color   color colorPrimaryDark  android drawable   color colorPrimary    gt   lt  selector gt    FYI  This is what the emulator showed before I added the color argument to  drawable tab selector

Have you tried checking the API   You will need to create a listener for the OnTabSelectedListener event  then when a user selects any tab you should check if it is the correct one  then change the background color using tabLayout setBackgroundColor int color   or if it is not the correct tab make sure you change back to the normal color again with the same method

As I found best and suitable option for me and it will work with animation too   You can use indicator it self as a background   You can set app tabIndicatorGravity  stretch  attribute to use as background   Example       lt android support design widget TabLayout         android id    id tab layout          android layout width  match parent          android layout height  wrap content          app tabIndicatorGravity  stretch          app tabSelectedTextColor   color white          app tabTextColor   color colorAccent  gt            lt android support design widget TabItem             android layout width  wrap content              android layout height  wrap content              android text  Chef    gt             lt android support design widget TabItem             android layout width  wrap content              android layout height  wrap content              android text  User    gt        lt  android support design widget TabLayout gt    Hope it will helps you
