    <p>I've been trying for a long time, and I think I have the code in place, but something is wrong because the item is not being added to the listView. Follows my code:</p> <pre><code>public class EditDoctors extends Activity implements OnClickListener { SimpleAdapter adapter; List&lt;HashMap&lt;String, String&gt;&gt; painItems = new ArrayList&lt;HashMap&lt;String, String&gt;&gt;(); ListView editDoc; int[] to; String[] from; EditText addDoc, docPos; String row1, row2; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.editdoc); addDoc = (EditText) findViewById(R.id.newDoc); docPos = (EditText)findViewById(R.id.docPos); editDoc = (ListView) findViewById(R.id.editDoc); TextView textview = new TextView(this); textview.setText("This is the Songs tab"); Button adddocs = (Button)findViewById(R.id.addbutton); adddocs.setOnClickListener(this); from = new String[] { "row_1", "row_2" }; to = new int[] { R.id.row1, R.id.row2 }; adapter = new Adapter(this, painItems, R.layout.mylistlayout,from, to); editDoc.setAdapter(adapter); } public class Adapter extends SimpleAdapter { HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); View row; public Adapter(Context context, List&lt;? extends Map&lt;String, String&gt;&gt; data, int resource, String[] from, int[] to) { super(context, data, resource, from, to); } } private void addItem() { HashMap&lt;String, String&gt; map = new HashMap&lt;String, String&gt;(); map.put("row_1", row1); map.put("row_2", row2); painItems.add(map); adapter.notifyDataSetChanged(); } @Override public void onClick(View arg0) { row1 = addDoc.getText().toString(); Toast.makeText(this, row1, Toast.LENGTH_SHORT).show(); row2 = docPos.getText().toString(); adapter.notifyDataSetChanged(); addItem(); } </code></pre> <p>}</p> <p>This should create a 2-lined listItem, but it doesn't, the lines are empty(no text). The Toast you see in the OnClickMethod returns the text just fine, but the item I add has nothing in it. Thanks in advance.</p>

Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
