public class QuizHelpActivity extends QuizActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help);

InputStream iFile = getResources().openRawResource(R.raw.quizhelp);
try {
TextView helpText = (TextView) findViewById(R.id.TextView_HelpText);
String strFile = inputStreamToString(iFile);
helpText.setText(strFile);
} catch (Exception e) {
Log.e(DEBUG_TAG, "InputStreamToString failure", e);

public String inputStreamToString(InputStream is) throws IOException {
StringBuffer sBuffer = new StringBuffer();
DataInputStream dataIO = new DataInputStream(is);
String strLine = null;
while ((strLine = dataIO.readLine()) != null) {
sBuffer.append(strLine + "\n");
