I have a file in the resource folder. How can you get his way, in order to read?

Here is the function that reads the file.

public String readTextFile(Context ctx, int resId) { InputStream inputStream = ctx.getResources().openRawResource(resId); InputStreamReader inputreader = new InputStreamReader(inputStream); BufferedReader bufferedreader = new BufferedReader(inputreader); String line; StringBuilder stringBuilder = new StringBuilder(); try { while ((line = bufferedreader.readLine()) != null) { stringBuilder.append(line); stringBuilder.append('\n'); } } catch (IOException e) { return null; } return stringBuilder.toString(); }

but how can I give him the path to the file (resId) if his name is not known?

I can get an array of all the elements that are there like this

 Field[] raw = R.raw.class.getFields();

But how to get from it the path to the file to transfer it to the function that I described above for reading? Suppose I need the path to the first file in this array ...

    Apparently this code for the drawable folder should help you if you replace it with raw:

     Field[] ID_Fields = R.raw.class.getFields(); int[] resArray = new int[ID_Fields.length]; for(int i = 0; i < ID_Fields.length; i++) { try { resArray[i] = ID_Fields[i].getInt(null); System.out.println(resArray[i]); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); } }
