Android学习--Fragment，androidkotlin面试题

android:text=“button”/>

新建一个右侧Fragment布局叫right_fragment_xml,一个文本框

然后分别新建LeftFragmet和RightFragment两个类继承Fragment，并且重写onCreateView()方法

package com.example.fragmenttest

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

class LeftFragment:Fragment() {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.left_fragment,container,false)
}
}

package com.example.fragmenttest

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