所以这就是我的困境，我真的很接近在游戏商店发布我的游戏。
在设备上测试我的应用时，我意识到点击主页按钮后，再次打开应用。一切都处理得很好。
然而，当按下后退按钮并再次打开应用程序时，我游戏中的纹理加载很奇怪，就像真的很奇怪。
Heres是应该看起来像什么的屏幕截图以及它不应该是什么......
这是显示应该是什么样子的链接 http://imgur.com/20QS2bx,bGyhbDJ#0
这是按下后退按钮后加载的那个http://imgur.com/20QS2bx,bGyhbDJ#1
经过一段时间的测试后，我认为问题在于，当单击后退按钮时，它会触发一个“退出”类型的功能，该功能应该退出应用程序。但是，由于某种原因，应用程序仍然存在于手机的背景中，导致在单击后退按钮后加载奇怪的纹理。如果我是正确的，我需要做什么才能处理这种行为。

修改
据我所知，将资产管理器更改为下面的内容应该可以正常工作，但是当我这样做时，我不能再使用管理器了，它会以红色突出显示并给出错误非静态字段管理器不能从非静态内容引用？
AssetManager manager = new AssetManager();
public static final String font = "fonts/mario.fnt";
public static final String jumpSound = "sounds/jumpSound.wav";
public static final String buttonClicked = "sounds/buttonClicked.wav";
public static final String passSound = "sounds/passSound.wav";
public static final String gameOver = "sounds/gameOver.mp3";
public static final String backgroundMusic = "sounds/backgroundMusic.wav";
public static final String background = "background.png";
public static final String floor = "floor.png";
public static final String foreground = "foreground.png";
public static final String fishAtlas = "sprite_animations/fishy_sprite_ani.atlas";
public static final String buttonAtlas = "ui/buttons.atlas";
public Assets() {
}
public static void load() {
manager.load(font, BitmapFont.class);
manager.load(jumpSound, Sound.class);
manager.load(buttonClicked, Sound.class);
manager.load(passSound, Music.class);
manager.load(gameOver, Music.class);
manager.load(backgroundMusic, Music.class);
manager.load(background, Texture.class);
manager.load(floor, Texture.class);
manager.load(foreground, Texture.class);
manager.load(fishAtlas, TextureAtlas.class);
manager.load(buttonAtlas, TextureAtlas.class);
}
答案 0 :(得分：0)
即使您关闭应用，背景中存在的对象的静态实例也存在问题。
当应用程序打开资产管理器的所有实例时，请确保您正在处置，归零和创建新文件。
使用
AssetManager manager;
...
manager.clear();
如果你使用了一些处理皮肤，并且如果你使用一些作为单例，那么将 null 设置为处理程序
