Android 加载时应用程序崩溃 uiskin.json
Android application crashes when loading uiskin.json
我在将 uiskin.json 文件加载到我的 Android 应用程序时遇到问题。
这是我写的一段测试代码：
private TextureAtlas buttonsAtlas;
private Skin skin;
private Skin buttonSkin;
private Stage stage;
private TextButton textButton;
private ImageButton imageButton;
@Override
public void create () {
stage = new Stage();
buttonsAtlas = new TextureAtlas(Gdx.files.internal("buttons.pack"));
buttonSkin = new Skin(buttonsAtlas);
skin = new Skin(Gdx.files.internal("uiskin.json"));
textButton = new TextButton("test", skin);
textButton.setPosition(Gdx.graphics.getWidth() / 4, Gdx.graphics.getHeight() / 4);
imageButton = new ImageButton(buttonSkin.getDrawable("imageUp"), buttonSkin.getDrawable("imageDown"));
imageButton.setPosition(Gdx.graphics.getWidth() / 2, Gdx.graphics.getHeight() / 2);
stage.addActor(imageButton);
stage.addActor(textButton);
Gdx.input.setInputProcessor(stage);
}
@Override
public void render () {
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
stage.act(Gdx.graphics.getDeltaTime());
stage.draw();
}
此代码在从桌面启动器启动时完美运行。但是，当导出 android 文件并将 APK 加载到模拟器中时（我使用的是 BlueStacks），程序就会崩溃。
当我评论这些行时
// skin = new Skin(Gdx.files.internal("uiskin.json"));
// textButton = new TextButton("test", skin);
// textButton.setPosition(Gdx.graphics.getWidth() / 4, Gdx.graphics.getHeight() / 4);
然后将应用程序导出到 Android，它在模拟器上运行得很好（所以当我使用带有我创建的按钮的 .pack 文件并将其加载到皮肤中时没有问题）。
我将问题缩小到这一行：skin = new Skin(Gdx.files.internal("uiskin.json"));
我正在使用 uiskin.json 文件以及来自 GitHub 的相关 uiskin.atlas 和 uiskin.png 文件：uiskin files.
对此有什么想法吗？我觉得很奇怪，我似乎无法在 Android 应用程序中使用皮肤。欢迎任何帮助，谢谢。

我解决了这个问题。根据堆栈跟踪，未找到文件 default.fnt，抛出一个 SerializationException.
显然，文件 default.fnt 和 default.png 也必须位于 Assets 文件夹中才能在 Android 上启动，但从桌面启动时则不需要。 （如果我错了纠正我）。
添加文件后，皮肤加载成功，应用程序不再崩溃。
我将此标记为解决了其他有相同问题的人的问题，以及对文件的 link：
default.fnt & default.png.
我在将 uiskin.json 文件加载到我的 Android 应用程序时遇到问题。
这是我写的一段测试代码：
private TextureAtlas buttonsAtlas;
private Skin skin;
private Skin buttonSkin;
private Stage stage;
private TextButton textButton;
private ImageButton imageButton;
@Override
public void create () {
stage = new Stage();
buttonsAtlas = new TextureAtlas(Gdx.files.internal("buttons.pack"));
buttonSkin = new Skin(buttonsAtlas);
skin = new Skin(Gdx.files.internal("uiskin.json"));
textButton = new TextButton("test", skin);
textButton.setPosition(Gdx.graphics.getWidth() / 4, Gdx.graphics.getHeight() / 4);
imageButton = new ImageButton(buttonSkin.getDrawable("imageUp"), buttonSkin.getDrawable("imageDown"));
imageButton.setPosition(Gdx.graphics.getWidth() / 2, Gdx.graphics.getHeight() / 2);
stage.addActor(imageButton);
stage.addActor(textButton);
Gdx.input.setInputProcessor(stage);
}
@Override
public void render () {
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
stage.act(Gdx.graphics.getDeltaTime());
stage.draw();
}
此代码在从桌面启动器启动时完美运行。但是，当导出 android 文件并将 APK 加载到模拟器中时（我使用的是 BlueStacks），程序就会崩溃。
当我评论这些行时
// skin = new Skin(Gdx.files.internal("uiskin.json"));

然后将应用程序导出到 Android，它在模拟器上运行得很好（所以当我使用带有我创建的按钮的 .pack 文件并将其加载到皮肤中时没有问题）。

我解决了这个问题。根据堆栈跟踪，未找到文件 default.fnt，抛出一个 SerializationException.
显然，文件 default.fnt 和 default.png 也必须位于 Assets 文件夹中才能在 Android 上启动，但从桌面启动时则不需要。 （如果我错了纠正我）。
添加文件后，皮肤加载成功，应用程序不再崩溃。
我将此标记为解决了其他有相同问题的人的问题，以及对文件的 link： default.fnt & default.png.
