How to get access to object

Question

I am new to java.
I have a directory with a txt file (R.raw). I want to get access with a command

InputStream in_s = res.openRawResource(R.raw.itemname);

where itemname is a dynamic string with a filename from a previous activity.

How do I can get open file in R.raw by a string "n0.txt"?

In javascript I can implement it like R.raw["n0.txt"] or R.raw.itemname.

Thanks in advance.

Write here the object please.. We need more details.. It is not clear — Aviad, May 29 '14 at 14:08
Your question is quite misleading.What do you mean by R.raw includes n0.txt and n1.txt ? — saurzcode, May 29 '14 at 14:09
If it's just a POJO, it probably has some getters you can call. In any case, you need to edit your question to show us what `R.raw` ***is***. — azurefrog, May 29 '14 at 14:14
Do you mean that you want to read the file called `itemname` (in this case `n0.txt`) in the `R.raw` directory? — azurefrog, May 29 '14 at 14:26

You need to use method getIdentifier().

Context context;
Resources res;

int itemId = res.getIdentifier("itemname", "raw", context.getPackageName());
InputStream is = res.openRawResource(itemId);

make sure you don't add file extension! ``"itemname.txt"`` is **wrong**, but ``"itemname"`` is correct – Oleksii K. May 29 '14 at 14:52
