2. Define your icons in drawable folder, and labels in strings.xml file

and reference them by their resource id in array ordered as y'all wish your icons to appear:

          individual int[] navIcons = {         R.drawable.ico_home,         R.drawable.ico_search,         R.drawable.ico_notification,         R.drawable.ico_profile }; individual int[] navLabels = {         R.cord.nav_home,         R.string.nav_search,         R.string.nav_notifications,         R.cord.nav_profile }; // another resouces array for active state for the icon individual int[] navIconsActive = {         R.drawable.ico_home_red,         R.drawable.ico_search_red,         R.drawable.ico_notification_red,         R.drawable.ico_profile_red };

3. setup your TabLayout with your ViewerPager:

          TabLayout navigation = (TabLayout) findViewById(R.id.navigation); navigation.setupWithViewPager(mainView/* the viewer pager object*/);                  

now customization function:

          // loop through all navigation tabs for (int i = 0; i < navigation.getTabCount(); i++) {     // inflate the Parent LinearLayout Container for the tab     // from the layout nav_tab.xml file that nosotros created 'R.layout.nav_tab     LinearLayout tab = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.nav_tab, zilch);      // get child TextView and ImageView from this layout for the icon and characterization     TextView tab_label = (TextView) tab.findViewById(R.id.nav_label);     ImageView tab_icon = (ImageView) tab.findViewById(R.id.nav_icon);      // gear up the characterization text past getting the actual string value by its id     // by getting the actual resource value `getResources().getString(string_id)`     tab_label.setText(getResources().getString(navLabels[i]));      // set the abode to be agile at start     if(i == 0) {         tab_label.setTextColor(getResources().getColor(R.color.efent_color));         tab_icon.setImageResource(navIconsActive[i]);     } else {         tab_icon.setImageResource(navIcons[i]);     }      // finally publish this custom view to navigation tab     navigation.getTabAt(i).setCustomView(tab); }
