Android 错误：二进制XML文件行：正在膨胀类片段

我有一个activity

main activity

，其中我有一个片段

signup\u fragment

我想从一个activity调用fragment，但它给出了一个异常，即

Binary-XML文件行#23:Binary-XML文件行#23:Error-inflating class fragment

和

由以下原因引起：java.lang.RuntimeException:com.example.PickComponents。MainActivity@d9ff1e7必须实现OnFragmentInteractionListener

下面是我的代码

main活动

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val fragment=Signup()
            supportFragmentManager.beginTransaction().add(R.id.sigup_fragment,fragment).commit()

    }

SignupFragment

class Signup : Fragment() {
    // TODO: Rename and change types of parameters
    private var param1: String? = null
    private var param2: String? = null
    private var listener: OnFragmentInteractionListener? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        arguments?.let {
            param1 = it.getString(ARG_PARAM1)
            param2 = it.getString(ARG_PARAM2)
        }
    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_signup, container, false)
    }

    // TODO: Rename method, update argument and hook method into UI event
    fun onButtonPressed(uri: Uri) {
        listener?.onFragmentInteraction(uri)
    }

    override fun onAttach(context: Context) {
        super.onAttach(context)
        if (context is OnFragmentInteractionListener) {
            listener = context
        } else {
            throw RuntimeException(context.toString() + " must implement OnFragmentInteractionListener")
        }
    }

    override fun onDetach() {
        super.onDetach()
        listener = null
    } }

问题就在这里
com.example.pickComponents.ImagesliderFragment
。未找到此片段或该片段存在问题

您应该在xml中使用
FrameLayout
而不是
Fragment

此外，您的
main活动应该在FragmentInteractionListener上实现
只需从..中删除
android:name
标记

并使用
FrameLayout
而不是fragment

或者你可以使用下面的代码

<FrameLayout
        android:layout_width="362dp"
        android:layout_height="98dp"
        android:id="@+id/sigup_fragment" app:layout_constraintEnd_toEndOf="parent"
        android:layout_marginEnd="8dp" app:layout_constraintStart_toStartOf="@+id/guideline"
        android:layout_marginStart="8dp" app:layout_constraintTop_toBottomOf="@+id/mood_tv"
        android:layout_marginTop="16dp"/>


您的XML在哪里？编辑后，这一行的问题仍然存在
android:name=“com.example.pickComponents.Signup”
它也在Signup.kt上给出了一个异常，
必须实现OnFragmentInteractionListener
我看到了您的代码。。据我所知，OnFragmentInteractionListener是不需要的，所以您可以删除与该侦听器相关的所有内容。
