在Android中为Tab设置安全Args

Question

我在设置片段页面适配器的安全参数时遇到麻烦。我无法设置该值，当它创建片段时会出现以下错误：

kotlin.KotlinNullPointerException at com.eae.mealbook.sleepquality.tabs.TabIngredienteFragment.onCreateView

我想问题出在设置包值的方式上，但是我在网络上找不到任何线索。这是我的适配器代码：

class PaginasSleepQualityAdapter(fm: FragmentManager, aux: Long) : FragmentPagerAdapter(fm)
{
    val ppp = aux

    override fun getItem(position: Int): Fragment {
        return when (position) {
            0 -> {
                val args = TabIngredienteFragmentArgs.Builder(ppp).build().toBundle()
                TabIngredienteFragment().arguments = args
                return TabIngredienteFragment()
            }
            //1 -> TabPasoFragment()//("Pescaderia")
            else -> {
                val args = TabPasoFragmentArgs.Builder(ppp).build().toBundle()
                TabIngredienteFragment().arguments = args
                return TabPasoFragment()//("Otros")
            }
        }
    }

和其中一个片段代码

class TabIngredienteFragment() : Fragment() {

    /**
     * Called when the Fragment is ready to display content to the screen.
     *
     * This function uses DataBindingUtil to inflate R.layout.fragment_sleep_quality.
     */
    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {

        // Get a reference to the binding object and inflate the fragment views.
        val binding: FragmentTabInputIngredienteBinding = DataBindingUtil.inflate(
            inflater, R.layout.fragment_tab_input_ingrediente, container, false)

        val application = requireNotNull(this.activity).application

        val arguments = TabIngredienteFragmentArgs.fromBundle(arguments!!)
