    <p>I'm writing an Android App that loads in data from an RSS Feed and lists the available items, and their description. There are 2 instances in which I use ArrayAdaptor. One works and one does not. The first one lists available feeds (right now the feed URLs are hard coded), and that one works. MainActivity.java</p> <pre><code>public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(R.layout.main); UpdateDisplay(); } private void UpdateDisplay() { ListView itemlist = (ListView) findViewById(R.id.itemlist); java.util.ArrayList&lt;String&gt; channels = new java.util.ArrayList&lt;String&gt;(); for(int i=0;i&lt;RSS_FEEDS.length;i++){ channels.add(RSS_FEEDS[i][0]); } ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, channels); itemlist.setAdapter(adapter); itemlist.setOnItemClickListener(this); } </code></pre> <p>The second ArrayAdaptor is used in another Activity that the first generates by selecting a feed to view. The RSSFeed is parsed, and it returns valid data (I have tested it outside of teh android environment, and it worked, recompiled it in android, and it still works, so the RSSParser is not the issue). RSSFeed.java </p> <pre><code>public void onCreate(Bundle b){ super.onCreate(b); setContentView(R.layout.feedlayout); UpdateDisplay(); } private void UpdateDisplay() { String feedUrl = null; Intent startingIntent = getIntent(); if(startingIntent != null){ Bundle args = startingIntent.getBundleExtra("android.intent.extra.INTENT"); if(args != null){ feedUrl = args.getString("URL"); feedTitle = args.getString("title"); }else{ feedTitle = "No Available RSS Feed"; } }else{ feedTitle = "Error finding parent Intent"; } ListView lv = (ListView)findViewById(R.id.storylist); if(feedUrl != null){ // Get Feed Items RSSFeed feed = getFeed(feedUrl); ArrayList&lt;String&gt; values = loadItems(feed); ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this,android.R.layout.simple_list_item_1,values); lv.setAdapter(adapter); lv.setOnItemClickListener(this); } TextView title = (TextView)this.findViewById(R.id.feedtitle); title.setText(feedTitle); Button backbutton = (Button)findViewById(R.id.backbutton_2); backbutton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { finish(); } }); } </code></pre> <p>I'm using the android.R.layout.simple_list_item_1 layout in both places, but it only works in the first. The backbutton Button also isn't displayed for some reason. Here's the feedlayout.xml file </p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;TextView android:id="@+id/feedtitle" android:layout_width="fill_parent" android:layout_height="wrap_content" /&gt; &lt;ListView android:id="@+id/storylist" android:layout_width="fill_parent" android:layout_height="wrap_content" /&gt; &lt;Button android:id="@+id/backbutton_2" android:text="Back" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; &lt;/LinearLayout&gt; </code></pre>

    2. COI have 3 layouts, and 2 of them have a back button, so I named one backbutton, and the other backbutton_2. the xml layout posted has backbutton_2. When I enter the Feed Activity, all that I can see onscreen is the first View - the TextView called "feedtitle".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
