 Here we learn , How to Create  a button Activity in Android studio Project. Follow this steps 

Here we use intent function to move another activity

Step 1:- open xml file and write code

activity.xml code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <Button
        android:id="@+id/bu2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="click here"/>

</RelativeLayout> 

Step 2:- create another Activity(which activity you want to go when button clicked)

path :- go res folder --> laylout folder then right click---> New--->Activity ---> empty Activity

Step 3:- go main activity .java File 

package com.ehowsongs.newapp;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {
    private Button bu2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bu2 = findViewById(R.id.bu2);

        bu2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                openactivity2();
            }
        });

    }

    private void openactivity2() {

        Intent intent = new Intent(this,Activity2.class);
        startActivity(intent);
    }
}

This the code you need to write to button Activity:-

 bu2 = findViewById(R.id.bu2);

    bu2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openactivity2();
        }
    });

}

private void openactivity2() {

    Intent intent = new Intent(this,Activity2.class);
    startActivity(intent);
}
