Question

当我在桌面上运行它时，我得到了正确的结果：

但是当我在我的Android手机（HTC One M8 1080p屏幕）上运行它时，它会显示更大的屏幕部分。我只希望它显示你在上面看到的内容，但它会在左下角显示该部分以及我希望在屏幕外显示的其他一些内容。

问题是，我的相机和视口设置与另一个屏幕完全相同，并且可以在另一个屏幕中使用。请帮我解决这个问题！

这是整个MenuScreen类：

这是MenuBackground类（创建以便后台可以移动）：

package com.xx4everPixelatedxx.gaterunner.sprites;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.math.Vector3;
import com.xx4everPixelatedxx.gaterunner.GateRunner;

/**

 */
public class MenuBackground {
    private Texture texture;
    private Sprite sprite;
    private Vector3 position;
    private Vector3 velocity;

    public MenuBackground(int i)
    {
        if(i == 1)
            position = new Vector3(0, 0, 0);
        else if(i == 2)
            position = new Vector3(0, GateRunner.HEIGHT * 2, 0);

        texture = new Texture(Gdx.files.internal("menu/title_background2.png"));
        sprite = new Sprite(texture);
        sprite.setSize(GateRunner.WIDTH, GateRunner.HEIGHT * 2 + 2);

        velocity = new Vector3(0, -3, 0);
    }

    public void update()
    {
        position.add(0, velocity.y, 0);
        if(position.y - 6 <= -2 * GateRunner.HEIGHT)
        {
            position.y = GateRunner.HEIGHT * 2;
        }
    }

    public Vector3 getVelocity() {
        return velocity;
    }

    public void setVelocity(Vector3 velocity) {
        this.velocity = velocity;
    }

    public Vector3 getPosition() {
        return position;
    }

    public void setPosition(Vector3 position) {
        this.position = position;
    }

    public Sprite getSprite() {
        return sprite;
    }

    public void setSprite(Sprite sprite) {
        this.sprite = sprite;
    }

    public Texture getTexture() {
        return texture;
    }

    public void setTexture(Texture texture) {
        this.texture = texture;
    }
}

GateRunner.WIDTH为480，GateRunner.HEIGHT为800。

问题得到解决。我所做的只是删除标题精灵，并重新创建它。我不知道为什么会这样。
