Getting Back The Old Bottombar

Just started a new app and when including a BottomNavigationView the result look like that : I really don't get where it come from and how can I get back to the old version that a

Solution 1:

by default BottomNavigationView add shiftingmode = true when its more than 3 items. so try this

staticvoidremoveShiftMode(BottomNavigationView view) {
    BottomNavigationMenuViewmenuView= (BottomNavigationMenuView) view.getChildAt(0);
    try {
        FieldshiftingMode= menuView.getClass().getDeclaredField("mShiftingMode");
        shiftingMode.setAccessible(true);
        shiftingMode.setBoolean(menuView, false);
        shiftingMode.setAccessible(false);
        for (inti=0; i < menuView.getChildCount(); i++) {
            BottomNavigationItemViewitem= (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 ", "Unable to get shift mode field"+e);
    } catch (IllegalAccessException e) {
        Log.e("ERROR", "Unable to change value of shift mode"+e);
    }
}


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

Solution 2:

You need to create helper class for this :

publicclassBottomNavigationViewHelper {
    publicstaticvoiddisableShiftMode(BottomNavigationView view) {
        BottomNavigationMenuViewmenuView= (BottomNavigationMenuView) view.getChildAt(0);
        try {
            FieldshiftingMode= menuView.getClass().getDeclaredField("mShiftingMode");
            shiftingMode.setAccessible(true);
            shiftingMode.setBoolean(menuView, false);
            shiftingMode.setAccessible(false);
            for (inti=0; i < menuView.getChildCount(); i++) {
                BottomNavigationItemViewitem= (BottomNavigationItemView) menuView.getChildAt(i);
                //noinspection RestrictedApi
                item.setShiftingMode(false);
                // set once again checked value, so view will be updated//noinspection RestrictedApi
                item.setChecked(item.getItemData().isChecked());
            }
        } catch (NoSuchFieldException e) {
            Log.e("BNVHelper", "Unable to get shift mode field", e);
        } catch (IllegalAccessException e) {
            Log.e("BNVHelper", "Unable to change value of shift mode", e);
        }
    }
}

In activity :

BottomNavigationViewbnav= (BottomNavigationView) findViewById(R.id.bottomnav);
 BottomNavigationViewHelper.disableShiftMode(bnav);
