Question

I have a helpdoc.txt file stored in res/raw within eclipse. It displays inside my application by using the below code:

public class HelpPage extends Activity {
/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.help);
    //read in
    InputStream iFile = getResources().openRawResource(R.raw.helpdoc);
        try {
            TextView helpText = (TextView) findViewById(R.id.TextView_HelpText);
            String strFile = inputStreamToString(iFile);
            helpText.setText(strFile);
        } catch (Exception e) {
            //nothing here
        }
}//end onCreate

    /**
         * Converts an input stream to a string
            */
        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");
            }//end while
                dataIO.close();
                is.close();
                return sBuffer.toString();
        }//end method  

It loads correctly, but does not all fit on the screen, when I try to scroll, I cannot read the rest of the text.

This is the related XML layout file for completeness: http://pastebin.com/PtskJbqt

Can anyone advise how I can scroll down to ensure the user can read the entire file?

Thanks.

Set: helpText.setMovementMethod(new ScrollingMovementMethod());
