Navigation Compopent的使用之从一个Fragment跳转到另一个Fragment

1、在build.gradle中添加依赖

   implementation 'androidx.navigation:navigation-fragment-ktx:2.4.2'
   implementation 'androidx.navigation:navigation-ui-ktx:2.4.2'
   implementation 'androidx.legacy:legacy-support-v4:1.0.0'

2、创建EnterDetailsFragment

package com.example.mykotlin2

import android.os.Bundle
import androidx.fragment.app.Fragment
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup


class EnterDetailsFragment : Fragment() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

    }

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

}

布局：fragment_enter_details.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16sp"
    tools:context=".EnterDetailsFragment">

    <!-- TODO: Update blank fragment layout -->
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:layout_marginBottom="16dp"
        android:gravity="center_horizontal"
        android:text="Enter your details below :"
        android:textColor="#212121"
        android:textSize="22sp"/>

    <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/til_name"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
        android:layout_width="match_parent"
        android:layout_
