read a text file android

Question

I am trying to make the computer read a text file full of words and add it to an ArrayList. I made it work on a regular Java application, but can't get it to work on Android. Can someone help me out?

try { FileInputStream textfl = (FileInputStream) getAssets().open("test.txt"); DataInputStream is = new DataInputStream(textfl); BufferedReader r = new BufferedReader(new InputStreamReader(is)); String strLine; while ((strLine = r.readLine()) != null) { tots.add(strLine); //tots is the array list } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }

I keep getting a error. The text file is 587kb, so could that be a problem?

What error are you getting? Edit your question to include this! — Argyle

How do you want it to be displayed? In a ListView so that each item is clickable? Or in a TextView? — FoamyGuy

i use to have FileInputStream textfl =new FileInputStream("test.txt"); but when i printed the size of the array list it was 0. i posted a question and someone told me to change it to FileInputStream textfl = (FileInputStream) getAssets().open("test.txt"); the first way worked in as regular java gui — steven minkus

try this.

private static String readTextFile(String fileName) { BufferedReader in = null; try { in = new BufferedReader(new InputStreamReader(getAssets().open(fileName))); String line; final StringBuilder buffer = new StringBuilder(); while ((line = in.readLine()) != null) { buffer.append(line).append(System.getProperty("line.separator")); } return buffer.toString(); } catch (final IOException e) { return ""; } finally { try { in.close(); } catch (IOException e) { // ignore // } } }
