Tips

Creation of models occurs through Builder pattern.

ModelBuilder requires two fields: icon and color. Title, badge title and selected icon is optional.

You can set selected icon. Resize and scale of selected icon equals to original icon.

Orientation automatically detected according to view size.

By default badge bg color is the active model color and badge title color is the model bg color. To reset colors just set AUTO_COLOR value to badge bg and title color.

By default badge sizes and title sizes is auto fit. To reset calculation just set AUTO_SIZE value to badge size and title size.

If your set ViewPager and enable swipe you can action down on active pointer and do like drag.

Init

Check out in code init:

final NavigationTabBar navigationTabBar = (NavigationTabBar) findViewById(R.id.ntb);
final ArrayList<NavigationTabBar.Model> models = new ArrayList<>();
models.add(
        new NavigationTabBar.Model.Builder(
                getResources().getDrawable(R.drawable.ic_first),
                Color.parseColor(colors[0])
        ).title("Heart")
                .badgeTitle("NTB")
                .build()
);
models.add(
        new NavigationTabBar.Model.Builder(
                getResources().getDrawable(R.drawable.ic_second),
                Color.parseColor(colors[1])
        ).title("Cup")
                .badgeTitle("with")
                .build()
);
models.add(
        new NavigationTabBar.Model.Builder(
                getResources().getDrawable(R.drawable.ic_third),
                Color.parseColor(colors[2])
        ).title("Diploma")
                .badgeTitle("state")
                .build()
);
models.add(
        new NavigationTabBar.Model.Builder(
                getResources().getDrawable(R.drawable.ic_fourth),
                Color.parseColor(colors[3])
        ).title("Flag")
                .badgeTitle("icon")
                .build()
);
models.add(
        new NavigationTabBar.Model.Builder(
                getResources().getDrawable(R.drawable.ic_fifth),
                Color.parseColor(colors[4])
        ).title("Medal")
                .badgeTitle("777")
                .build()
);
navigationTabBar.setModels(models);
navigationTabBar.setViewPager(viewPager, 2);

navigationTabBar.setTitleMode(NavigationTabBar.TitleMode.ACTIVE);
navigationTabBar.setBadgeGravity(NavigationTabBar.BadgeGravity.BOTTOM);
navigationTabBar.setBadgePosition(NavigationTabBar.BadgePosition.CENTER);
navigationTabBar.setTypeface("fonts/custom_font.ttf");
navigationTabBar.setIsBadged(true);
navigationTabBar.setIsTitled(true);
navigationTabBar.setIsTinted(true);
navigationTabBar.setIsBadgeUseTypeface(true);
navigationTabBar.setBadgeBgColor(Color.RED);
