}

BaseFragmentAdapter.java

public class BaseFragmentAdapter extends FragmentPagerAdapter {
    private List<String> fragments;
    private int [] Imgs= {
        R.mipmap.mn1,
        R.mipmap.mn2,

        super(fm);
        this.fragments= new ArrayList<>();
        fragments.add("首页");
        fragments.add("关注");
        fragments.add("消息");
        fragments.add("我的");
    }

    @Override
    public Fragment getItem(int position) {
        return BaseFragment.newInstance(Imgs[position]);
    }

    @Override
    public int getCount() {
        return fragments.size();
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return fragments.get(position);
    }
}

不知到为什么我通过下面这种方式与ViewPager联动的时候,导航的图标颜色总是不对,如果有使用过这个的童鞋还希望指点!见笑了

ContextCompat.getColor(context, R.color.firstColor)
 bottomNavigationView.setUpWithViewPager(yourPager , colorResources , imageResources);
