How to remove icon animation for bottom navigation view in android

Question

I have implemented Bottom Navigation View from Design Support Library 25 in my project. I have 5 icons in the view. whenever an icon is selected it's having some animation. But when 3 or fewer icons is not showing any animations. I want to remove that animation and need only some color change for the icon. How can I achieve this? Done enough googling, but couldn't find the solution. Please help. Thanks.

Answer 1

got answer from this thread.

To remove animation or shift mode.

Implementation of BottomNavigationView has condition: when there is more than 3 items then use shift mode.

Create helper class

import android.support.design.internal.BottomNavigationItemView;  import android.support.design.internal.BottomNavigationMenuView;  import android.support.design.widget.BottomNavigationView;  import android.util.Log; import java.lang.reflect.Field;  public class BottomNavigationViewHelper {      public static void disableShiftMode(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);                 //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);         }      }  }  

Usage

BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation_bar); BottomNavigationViewHelper.disableShiftMode(bottomNavigationView); 

Answer 2

I tryed this and it worked well

BottomNavigationViewHelper.disableShiftMode(bottomNavigationView);

Or this code mainactivity.xml

app:labelVisibilityMode="unlabeled"

Answer 3

I just add this code on dimens.xml, and its work like a charm!

<dimen name="design_bottom_navigation_active_text_size" tools:override="true">@dimen/design_bottom_navigation_text_size</dimen>
