Question

I am working on an RSS reader and I can’t seem to figure out why me text is not lining up properly.

I have looked at posts similar in nature such as:

• android – TwoLineListItem text alignment
• http://blog.thisisfeifan.com/2011/10/2-lines-text-in-single-choice-listview.html
• http://developerlife.com/tutorials/?p=327

I just can’t understand why mine won’t work right.

Can anyone explain why my text is not lining up properly inside of my listview?

This is the class that the view is based on:

public class RSSReader extends Activity implements OnItemClickListener
{

public final String RSSFEEDOFCHOICE = "http://app.calvaryccm.com/mobile/android/v1/devos";

public final String tag = "RSSReader";
private RSSFeed feed = null;
private static final DateFormat PARSING_PATTERN = 
        new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss z", Locale.US); 
    private static final DateFormat FORMATTING_PATTERN = 
        new SimpleDateFormat("EEEE, MMMM dd, yyyy"); 

/** Called when the activity is first created. */

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);

    // go get our feed!
    feed = getFeed(RSSFEEDOFCHOICE);

    // display UI
    UpdateDisplay();

}


private RSSFeed getFeed(String urlToRssFeed)
{
    try
    {
        // Setup the URL
       URL url = new URL(urlToRssFeed);

       // Create the factory
       SAXParserFactory factory = SAXParserFactory.newInstance();
       // create a parser
       SAXParser parser = factory.newSAXParser();

       // Create the reader (scanner)
       XMLReader xmlreader = parser.getXMLReader();
       // Instantiate our handler
       RSSHandler theRssHandler = new RSSHandler();
       // Assign our handler
       xmlreader.setContentHandler(theRssHandler);
       // Get our data via the url class
       InputSource is = new InputSource(url.openStream());
       // Perform the synchronous parse           
       xmlreader.parse(is);
       // Get the results - should be a fully populated RSSFeed instance, or null on error
       return theRssHandler.getFeed();
    }
    catch (Exception ee)
    {
        // If we have a problem, simply return null
        System.out.println(ee.getMessage());
        System.out.println(ee.getStackTrace());
        System.out.println(ee.getCause());
        return null;
    }
}
public boolean onCreateOptionsMenu(Menu menu) 
{
    super.onCreateOptionsMenu(menu);
    menu.add(Menu.NONE, 0, 0, "Refresh");
    Log.i(tag,"onCreateOptionsMenu");
    return true;
}

public boolean onOptionsItemSelected(MenuItem item){
    switch (item.getItemId()) {
    case 0:

        Log.i(tag,"Set RSS Feed");
        return true;
    case 1:
        Log.i(tag,"Refreshing RSS Feed");
        return true;
    }
    return false;
}


private void UpdateDisplay()
{
    ListView itemlist = (ListView) findViewById(R.id.itemlist);     

    //ArrayAdapter<RSSItem> adapter = new ArrayAdapter<RSSItem>(this,android.R.layout.simple_list_item_1,feed.getAllItems());

    List<Map<String, String>> data = new ArrayList<Map<String, String>>();
    for (RSSItem item : feed.getAllItems()) {
        Map<String, String> datum = new HashMap<String, String>(2);
        datum.put("title", item.getTitle());

        String outputDate;
        try {
           Date date = PARSING_PATTERN.parse(item.getPubDate());
           outputDate = FORMATTING_PATTERN.format(date);
        } catch (ParseException e) {
           outputDate = "Invalid date"; // Date parse error
        } 
        datum.put("date", outputDate);
        data.add(datum);
    }
    SimpleAdapter adapter = new SimpleAdapter(this, data,
                                              android.R.layout.simple_list_item_2,
                                              new String[] {"title", "date"},
                                              new int[] {android.R.id.text1,
                                                         android.R.id.text2});

    itemlist.setAdapter(adapter);

    itemlist.setOnItemClickListener(this);

    itemlist.setSelection(0);

}

 @Override
 public void onItemClick(AdapterView parent, View v, int position, long id)
 {

     //Log.i(tag,"item clicked! [" + feed.getItem(position).getTitle() + "]");      

     Intent itemintent = new Intent(this,ShowDescription.class);

     Bundle b = new Bundle();
     b.putString("title", feed.getItem(position).getTitle());
     b.putString("description", feed.getItem(position).getDescription());
     b.putString("link", feed.getItem(position).getLink());
     b.putString("pubdate", feed.getItem(position).getPubDate());
     b.putString("enclosure", feed.getItem(position).getEnclosure());

     itemintent.putExtra("android.intent.extra.INTENT", b);

     startActivity(itemintent);

 }

}

This is my XML for the previous class:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>

<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/itemlist" android:layout_gravity="left"
/>    
</LinearLayout>

This a visual of what is happening:

Answer 1

Looks good. Could it be that the fields are coming in with spaces? Try pulling the title off with a trim, or running the debugger to see if it’s not your code but rather the data.

item.getTitle().trim();
