Before starting this blog you should know the BottomNavigationView in Android. So First read our previous blog on the BottomNavigationView,

How to use BottomNavigationView in android

Ok, You have read the above blog. So we can start now.

Actually, when you use the more then 4 items in BottomNavigationView then Android automatically enable the shift mode.

How to remove or disable this mode

Create a class named BottomNavigationViewHelper

class BottomNavigationViewHelper { static void removeShiftMode(BottomNavigationView view) { BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0); try { Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode"); shiftingMode.setAccessible(true); shiftingMode.setBoolean(menuView, false); shiftingMode.setAccessible(false); for (int i = 0; i < menuView.getChildCount(); i++) { BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i); item.setShiftingMode(false); // set once again checked value, so view will be updated item.setChecked(item.getItemData().isChecked()); } } catch (NoSuchFieldException e) { Log.e("ERROR NO SUCH FIELD", "Unable to get shift mode field"); } catch (IllegalAccessException e) { Log.e("ERROR ILLEGAL ALG", "Unable to change value of shift mode"); } } }

class BottomNavigationViewHelper {

    static void removeShiftMode(BottomNavigationView view) {
        BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
        try {
            Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
            shiftingMode.setAccessible(true);
            shiftingMode.setBoolean(menuView, false);
            shiftingMode.setAccessible(false);
            for (int i = 0; i < menuView.getChildCount(); i++) {
                BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
                item.setShiftingMode(false);
                // set once again checked value, so view will be updated
                item.setChecked(item.getItemData().isChecked());
            }
        } catch (NoSuchFieldException e) {
            Log.e("ERROR NO SUCH FIELD", "Unable to get shift mode field");
        } catch (IllegalAccessException e) {
            Log.e("ERROR ILLEGAL ALG", "Unable to change value of shift mode");
        }
    }
}

and pass your BottomNavView to this function,

BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation); BottomNavigationViewHelper.removeShiftMode(bottomNavigationView);
