我正在尝试从应用程序的数据目录中访问数据。我可以加载default.fnt
文件,但它告诉我无法找到关联的default.png
。 如何让系统识别文件?有没有我设置错误的东西?

我已检查过文件是否存在以及他们是否拥有合适的所有者/组,甚至将权限设置为777只是为了测试。
我已经看到了其他一些问题,其中问题出在项目中的 assets 文件夹中,但我没有使用assets文件夹。并且代码能够找到位于.png。
旁边的.fnt文件info face =“Droid Sans”size = 17 bold = 0 italic = 0 charset =“”unicode = 0 stretchH = 100 smooth = 1 aa = 1 padding = 0,0,0,0 spacing = 1,1 common lineHeight = 20 base = 18 scaleW = 256 scaleH = 128 pages = 1 packed = 0 page id = 0 file =“default.png”chars count = 95
如果有帮助,这是我用来获取文件句柄的代码:
FileHandle dataDir = Gdx.files.local("data");
FileHandle gfxDir = dataDir.child("gfx");
if(!gfxDir.isDirectory())
{
//mkdirs will make all directories, so this includes the "data" dir
gfxDir.mkdirs();
}
FileHandle spritesDir = gfxDir.child("sprites");
if(!spritesDir.isDirectory())
{
spritesDir.mkdirs();
}
FileHandle fontsDir = gfxDir.child("fonts");
if(!fontsDir.isDirectory())
{
fontsDir.mkdirs();
}
P.S。字体文件和png在属于assets文件夹时工作。所以我假设它们设置得当。

您遇到来自FileNotFound
的{{1}}个例外,但该文档明确指出android.content.res.AssetManager.open
。
但是,你不直接打电话......
啊,only works with "files bundled as assets"使用Gdx.files.internal
加载字体纹理:
public BitmapFont (BitmapFontData data, TextureRegion region, boolean integer) {
this.region = region == null ? new TextureRegion(new Texture(Gdx.files.internal(data.imagePath), false)) : region;
...
(看起来像Libgdx中的一个错误就是假设字体纹理文件是“内部的”,但我不确定它们应该如何解决...)
我认为您可以通过在loadFonts
方法中调用Libgdx BitmapFont constructor来解决此问题。
