java - Resources.getSystem().openRawResource(random.txt) 返回 Resource$NotFoundException

Question

基于 1.6 SDK4

InputStream is = Resources.getSystem().openRawResource(R.raw.vortexrules);

这条线给我带来了无尽的麻烦......

我的 R.java 显示:

public static final class raw {
    public static final int vortexrules=0x7f040000;

这告诉我编译器正在识别文本文件和文件夹并将它们设置为资源。

当我运行上面的代码时，试图将 InputStream 设置为我得到的文本文件:

在 LogCat 之外。

这告诉我它找不到具有该 ID 的资源，但它只是从 R.java 获得了 ID，R.java 正在从编译器获取信息。

此时我完全迷失了。

任何帮助将不胜感激...

正如 stealthcopter 在评论中所说，您不需要文件扩展名!
