    <p>I'm trying to use a list view, and when I add an item to the ArrayList of its ListAdapter and call notifyDataSetChanged, it throws an exception. Calling the addItem routine below will throw an exception.</p> <p>The message says Source not Found, and then this: // Compiled from DataSetObservable.java (version 1.5 : 49.0, super bit) // Signature: Landroid/database/Observable; public class android.database.DataSetObservable extends android.database.Observable {</p> <p>// Method descriptor #8 ()V // Stack: 3, Locals: 1 public DataSetObservable(); 0 aload_0 [this] 1 invokespecial android.database.Observable() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 5] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: android.database.DataSetObservable</p> <p>My initialization code:</p> <pre><code> tickerList = (ListView)findViewById(R.id.ListView01); tickerModel = new StockAdapter(stocks); tickerList.setAdapter(tickerModel); </code></pre> <p>I've included my custom adapter class. (Modified from an online example)</p> <pre><code>private class StockAdapter extends BaseAdapter { private ArrayList &lt;Stockdata&gt;mData = new ArrayList&lt;Stockdata&gt;(); private LayoutInflater mInflater; public StockAdapter(ArrayList&lt;Stockdata&gt;rows) { mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); mData = rows; } public void addItem(Stockdata item) { mData.add(item); notifyDataSetChanged(); } @Override public int getCount() { return mData.size(); } @Override public Stockdata getItem(int position) { return mData.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { System.out.println("getView " + position + " " + convertView); ViewHolder holder = null; if (convertView == null) { convertView = mInflater.inflate(R.layout.row, null); holder = new ViewHolder(); holder.textView = (TextView)convertView.findViewById(R.id.SYMBOL_CELL); convertView.setTag(holder); } else { holder = (ViewHolder)convertView.getTag(); } holder.textView.setText(mData.get(position).getSymbol()); return convertView; } } public static class ViewHolder { public TextView textView; } </code></pre>

    1. COtry passing `tickerList` as the second argument to `mInflater.inflate()`. That is a really strange exception. Can you try to paste it with a four space indent so it can be read more easily?

    2. COI don't believe that is a stack trace. That looks a bit like an Eclipse window showing the halted thread. Try using `adb logcat`, DDMS, or the DDMS perspective in Eclipse to get the exception information.

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.
