底部有五个项目导航栏。当从第三个开始的项目返回到前两个时，它将闪回。我只在第一项中使用了幻灯片。
在mainactivity中使用bottomnavigationview

public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            switch (item.getItemId()) {
                case R.id.tab_one:
                    viewPager.setCurrentItem(0);
                    return true; //返回true,否则tab按钮不变色,未被选中
                case R.id.tab_two:
                    viewPager.setCurrentItem(1);
                    return true;
                case R.id.tab_three:
                    viewPager.setCurrentItem(2);
                    return true;
                case R.id.tab_four:
                    viewPager.setCurrentItem(3);
                    return true;
                case R.id.tab_five:
                    viewPager.setCurrentItem(4);
                    return true;
                default:
                    break;
            }

            return false;

在碎片中使用滑动布局

fragments.add(new AFFragment());
        fragments.add(new ASFragment());
        fragments.add(new ATFragment());
        tabLayout.setViewPager(viewPager,titles, getActivity(),fragments);

>   java.lang.ArrayIndexOutOfBoundsException: length=3; index=3
