    int res = 0;
    for (int i = 0; i <=79; i = i + 1) {
        if (s.equals(d[i])){
            res=R.raw.(d[i])
        }
    } 
    inputstream = getResources().openRawResource(res);

You can use getIdentifier (String name, String defType, String defPackage) for fetching resource id dynamically,

ArrayList<Integer> id = new ArrayList<Integer>();
for (int i = 0; i <= 79; i++) {
  id.add(getResources().getIdentifier("d"+i, "raw", getPackageName()));
}

Now you will have all the resources id's inside id ArrayList

i put this , but i get force close ??? int id[] = new int[79]; for (int i = 0; i <= 79; i++) { id[i] = getResources().getIdentifier("d"+i, "raw", getPackageName()); if (s.equals(d[i])) {res=id[i];z=d[i];} } – hkh114 Sep 18 '12 at 10:28

I have 6 variations of resources in one place I need to read.

    try
     {
        for (int i = 0; i < 6; i++ )
         {
              String fname = "p" + i;
              int id = context.getResources().getIdentifier(fname, "drawable", "com.example.yourproject");
              if (id == 0)
              {
                  Log.e(TAG, "Lookup id for resource '"+fname+"' failed");
                  // graceful error handling code here
              }
             scoresBm[i] =  (Bitmap) BitmapFactory.decodeResource(context.getResources(), id);
         }
    }
    catch(Exception E)
    {
    }
