LibGDX 游戏在桌面上按预期运行，但在 Android 设备上不正常

Question

我遇到了一些问题。我对 libGDX 有点陌生，对出了什么问题一无所知。
在这里，我有一个包含三个文本按钮实例的状态。它在我的桌面上运行良好，但在我的手机上崩溃。我不确定问题出在哪里，但是当我注释掉其中两个实例的代码时，它可以在我的手机上运行。

public class MenuStateTest extends State {

Stage stage;
TextButton button, button2, button3;
TextButton.TextButtonStyle textButtonStyle;
BitmapFont font;
Skin skin;
TextureAtlas buttonAtlas, button2Atlas, button3Atlas;

public MenuStateTest(GameStateManager gsm) {
    super(gsm);
    stage = new Stage();
    Gdx.input.setInputProcessor(stage);
    font = new BitmapFont();
    skin = new Skin();

    buttonAtlas = new TextureAtlas("buttonTest.pack");
    skin.addRegions(buttonAtlas);
    textButtonStyle = new TextButton.TextButtonStyle();
    textButtonStyle.font = font;
    textButtonStyle.up = skin.getDrawable("1BBlock");
    textButtonStyle.down = skin.getDrawable("T1BBlock");
    button = new TextButton("", textButtonStyle);
    stage.addActor(button);
    button.setPosition(20,200);

    button2Atlas = new TextureAtlas("button2Test.pack");
    skin.addRegions(button2Atlas);
    textButtonStyle = new TextButton.TextButtonStyle();
    textButtonStyle.font = font;
    textButtonStyle.up = skin.getDrawable("2BBlock");
    textButtonStyle.down = skin.getDrawable("T2BBlock");
    button2 = new TextButton("", textButtonStyle);
    stage.addActor(button2);
    button2.setPosition(175,200);

    button3Atlas = new TextureAtlas("button3Test.pack");
    skin.addRegions(button3Atlas);
    textButtonStyle = new TextButton.TextButtonStyle();
    textButtonStyle.font = font;
    textButtonStyle.up = skin.getDrawable("3BBlock");
    textButtonStyle.down = skin.getDrawable("T3BBlock");
    button3 = new TextButton("", textButtonStyle);
    stage.addActor(button3);
    button3.setPosition(330,200);
}

@Override
protected void render(SpriteBatch sb) {
    stage.draw();

任何帮助将不胜感激。
谢谢。

编辑：这是我从 logcat 中得到的结果

Answer 1

如果它运行在桌面上而不运行在Android上，我能想到的可能有两种：

1. 检查包含button2Test.pack 的文件夹的路径 文件。 Android 路径是相对于 assets 文件夹的，而 desktop 使用相对于根文件夹的路径。
2. 例如检查文件名button2Test.pack的大小写 是否应该是Button2Test.pack、button2test.PACK 或 类似的组合。因为 Windows 接受任何案例文件，但 Android 没有。
