如何在libGDX中的sprite类中插入背景图片？

Sprite sprite = new Sprite();

Texture texture = new Texture(Gdx.files.internal("background.png"));

sprite.setTexture(texture);

sprite.setPosition(x, y); // 设置Sprite的位置，x和y分别是横纵坐标
sprite.setSize(width, height); // 设置Sprite的大小，width和height分别是宽度和高度

sprite.draw(batch);

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class MyGame extends ApplicationAdapter {
    private SpriteBatch batch;
    private Sprite sprite;
    
    @Override
    public void create() {
        batch = new SpriteBatch();
        
        // 加载背景图片资源
        Texture texture = new Texture(Gdx.files.internal("background.png"));
        
        // 创建Sprite对象并设置背景图片
        sprite = new Sprite(texture);
        
        // 设置Sprite对象的位置和大小
        sprite.setPosition(0, 0);
        sprite.setSize(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
    }
    
    @Override
    public void render() {
        Gdx.gl.glClearColor(0, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        
        batch.begin();
        
        // 绘制Sprite对象
        sprite.draw(batch);
        
        batch.end();
    }
    
    @Override
    public void dispose() {
        batch.dispose();
        sprite.getTexture().dispose();
    }
}
