我目前正在创建一个基本应用程序，试图在android的导航栏中使用片段。每当我运行该应用程序并按相应的菜单项（调用一个片段）时，该应用程序就会崩溃。
我对android开发和Kotlin还是很陌生，目前正在做一个高中设计项目，没有任何编码和应用程序开发方面的知识，因此我对很多术语不熟悉。 。这个应用程序主要是根据我从多个YouTube视频中收集的点点滴滴制作而成。我认为此崩溃可能是由于我的经验不足造成的，因此在解决此问题方面将提供任何帮助。
只要我的应用崩溃，这就是我从Logcat获得的信息。

这是我MainActivity的一部分（主要只是用于创建导航视图的模板）
override fun onNavigationItemSelected(item: MenuItem): Boolean {
when (item.itemId) {
R.id.intro -> {
startActivity(Intent(this, MainActivity::class.java))
}
R.id.benefits -> {
loadBenefits(fragl = BenefitsFragment())
}
R.id.connecting-> {
}
R.id.socialmedia -> {
}
R.id.internetcomms -> {
}
R.id.setupandsafety -> {
}
R.id.newsmedia -> {
}
R.id.fakenews -> {
}
R.id.utilities -> {
}
R.id.onlineshopping -> {
}
R.id.onlinesafety -> {
}
}
drawer_layout.closeDrawer(GravityCompat.START)
return true
}
private fun loadBenefits (fragl: BenefitsFragment) {
val fm = supportFragmentManager.beginTransaction()
fm.replace(R.id.benefits, fragl)
fm.commit()
我认为BenefitsFragment可能与此有关，因为它在Logcat中被提及，所以这里是
package com.example.first_try
import android.os.Bundle
import android.support.v4.app.Fragment
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
class BenefitsFragment : Fragment() {
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
return LayoutInflater.from(container?.context).inflate(R.layout.fragment_benefits, container, false)
}
}
