在点击Backpress时,如何在BottomNavigationView中突出显示相应的片段项图标?

我有一个 底部导航视图 具有 三 项目 屏幕底部的选项卡。每个项目选项卡都有 两段 在里面。我点击这个流程, 项1碎片->项2碎片->项3碎片->子项3碎片1->子项3碎片2 . 所以当我 背压 从 项目3碎片,项目2碎片 和 ITEM1片段 相应的项目图标将突出显示。

我指的是这个职位 Change BottomNavigationView Icons on Back Button clicked

我需要的是当我从 ITEM3-片段 流量应该是 子项3分段1(突出显示第3项图标)->项3分段(突出显示第3项图标)->项2分段(突出显示第2项图标)->项1分段(突出显示第1项图标)

我用 transaction.addTobackStack(“subfrag”);

Deque<Integer> mStack = new ArrayDeque<>();
boolean isBackPressed  = false;

private void setBottomNavigationView() {
    mBottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            switch (item.getItemId()) {
                case R.id.ic_home:
                     if(!isBackPressed) {
                       pushFragmentIntoStack(R.id.ic_home);
                   }
                    isBackPressed = false
                    setFragment(HomeFragment.newInstance(), HOME_FRAGMENT);
                    return true;
                case R.id.ic_search:
                    if(!isBackPressed) {
                       pushFragmentIntoStack(R.id.ic_search);
                   }
                    isBackPressed = false
                    setFragment(SearchFragment.newInstance(), SEARCH_FRAGMENT);
                    return true;
                case R.id.ic_circle:
                    if(!isBackPressed) {
                       pushFragmentIntoStack(R.id.ic_circle);
                   }
                    isBackPressed = false
                    setFragment(ShareFragment.newInstance(), SHARE_FRAGMENT);
                    return true;

                default:
                    return false;
            }
        }
    });
    mBottomNavigationView.setOnNavigationItemReselectedListener(new 
          BottomNavigationView.OnNavigationItemReselectedListener() {
        @Override
        public void onNavigationItemReselected(@NonNull MenuItem item) {

        }
    });
 mBottomNavigationView.setSelectedItemId(R.id.ic_home);
 pushFragmentIntoStack(R.id.ic_home);
}

private void pushFragmentIntoStack(int id)
{
    if(mStack.size() < 3)
    {
        mStack.push(id);
    }
    else
    {
        mStack.removeLast();
        mStack.push(id);
    }
}

private void setFragment(Fragment fragment, String tag) {
    FragmentTransaction transaction = mFragmentManager.beginTransaction();
    transaction.replace(R.id.container, fragment, tag);
    transaction.commit();
}

@Override
public void onBackPressed() {
    if(mStack.size() > 1)
    {
        isBackPressed = true;
        mStack.pop();
        mBottomNavigationView.setSelectedItemId(mStack.peek());
    }
    else 
    {
        super.onBackPressed();
    }
}
