没有得到的包名 [英] Not getting the package name

问题描述

我试图找回从原始文件夹中的动态code中的文件，如下

I'm trying to retrieve the file from the raw folder dynamically the code as below

try{
        DataInputStream dataIO= new DataInputStream(getResources().getIdentifier("raw/"+chapter, null ,<what to write>);
        String strLine= null;
        while((strLine = dataIO.readLine())!=null){
            buffer.append(strLine);
            buffer.append("\n");
        }
        dataIO.close();
    }catch(Exception e){}

如果我直接在写什么中输入包的名称，它显示错误。请给一些关于它的主意。

If I type the package name directly in the "what to write" section, it showing the error. Please give some idea about it.

推荐答案

假设你想要动态检索原始资源的ID，下面的code段将是有益的：

Assuming that you want to retrieve the id of a raw resource dynamically, the following code snippet would be useful:

int id = getResources().getIdentifier(chapter, "raw", getPackageName());

和您的DataInputStream以对象应该被这样构成：

and your DataInputStream object should be constructed thus:

DataInputStream dataIO= new DataInputStream(getResources().openRawResource(id));
