I have added buttons to my code, but when I go to "resize", they get bigger or wider and it looks very bad. How can I resize the window and keep the button aspect ratio?

This is my code:


package com.mygdx.game;

import com.badlogic.gdx.Game;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

import com.mygdx.game.screen.MainMenuScreen;

public class gamename extends Game {

    public static final int WIDTH = 760;
    public static final int HEIGHT = 520;
    public SpriteBatch batch;

    public void create() {  
        batch = new SpriteBatch();
        this.setScreen(new MainMenuScreen(this)); 
    public void render(){  

2)And this is the menu, here i use the image to view the buttons. MainMenu: package com.mygdx.game.screen;

import com.badlogic.gdx.Gdx;

import com.badlogic.gdx.Screen;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;

import com.mygdx.game.gamename;

public class MainMenuScreen implements Screen{
    private static final int PLAY_BUTTON_WIDTH = 150;
    private static final int PLAY_BUTTON_HEIGHT = 80;
    private static final int OPTIONS_BUTTON_WIDTH = 150;
    private static final int OPTIONS_BUTTON_HEIGHT = 80;
    gamename game;
    Texture playButtonActive;
    Texture playButtonInactive;
    Texture optionsButtonActive;
    Texture optionsButtonInactive;
    public MainMenuScreen (gamename game){
        this.game = game;
        playButtonActive = new Texture("play1.png");
        playButtonInactive = new Texture("play2.png");
        optionsButtonActive = new Texture("options1.png");
        optionsButtonInactive = new Texture("options2.png");

    public void show() {

    public void render(float f) {  //Colore e carica bottoni
        Gdx.gl.glClearColor(1, 1, 1, 1);
        game.batch.draw(playButtonActive, 240, 150, PLAY_BUTTON_WIDTH, PLAY_BUTTON_HEIGHT);

    public void resize(int i, int i1) {

    public void pause() {

    public void resume() {

    public void hide() {

    public void dispose() {

I would like the button to be the same even if I manually increase the page size. Maybe i need to use ViewPort, but the tutorial doesn't explain how to use it. Can anyone help me insert it into my code?
