如何在android中删除底部导航视图的图标动画

问题描述

我已在项目中的设计支持库25中实现了底部导航视图。我在视图中有5个图标。每当选择一个图标时，它就会有一些动画。但是当3个或更少的图标没有显示任何动画时。我想删除该动画，只需要对图标进行一些颜色更改。我怎样才能做到这一点？做了足够的谷歌搜索，但找不到解决方案。请帮忙。谢谢。

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.

从这里得到答案。

删除动画或班次模式。

<$ c $的实施c> BottomNavigationView 有条件：当有超过3项时，则使用shift模式。

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

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);
        }
    }
}

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