相機和視口無法按預期工作（Android LibGDX）

Question

當我在桌面上運行它時，我得到正確的結果：

但是，當我在Android手機（HTC One M8 1080p屏幕）上運行它時，它會在屏幕上顯示更大的部分。 我只希望它顯示您在上方看到的內容，但是它在左下角顯示該部分以及其他一些我想在屏幕外顯示的內容。

問題是，我的攝像頭和視口的設置與另一個屏幕完全相同，並且可以在另一個屏幕上正常工作。 請幫我解決這個問題！

這是整個MenuScreen類：

這是MenuBackground類（已創建，因此背景可以移動）：

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是480，GateRunner.HEIGHT是800。

該問題已解決。 我要做的就是刪除標題精靈，然后重新創建它。 我不知道為什么會這樣。
