buttons in fragment(android studio)

Question

I'm working on my app, and came to a huge problem. I need to implement buttons in my fragments and can't find a normal solution that works. this is the code:

package com.example.konjicdiscover10;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;

public class SettingsFragment extends Fragment {

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, 
@Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.fragment_settings, container, false);


    }
}

and XML

<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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:paddingTop="60dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingBottom="14dp"
android:background="@color/white">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">


    <Button
        android:id="@+id/button"
        android:layout_width="350sp"
        android:layout_height="50sp"
        android:layout_centerHorizontal="true"
        android:textSize="11sp"
        android:layout_marginVertical="20dp"
        android:text="dark mode(in preparation)" />

    <Button
        android:id="@+id/button2"
        android:layout_width="350sp"
        android:layout_height="50sp"
        android:layout_centerHorizontal="true"
        android:layout_marginVertical="80dp"
        android:text="Languages(in preparation)"
        android:textSize="11sp"/>
</RelativeLayout>

</ScrollView>

basically what I'm looking for is that a buttons can lead to a new fragments or activities where content will be.
