    <p>I used an <code>EditText</code> to do the job.</p> <p>First I created two copies of the array to hold the list of data to search:</p> <pre><code>List&lt;Map&lt;String,String&gt;&gt; vehicleinfo; List&lt;Map&lt;String,String&gt;&gt; vehicleinfodisplay; </code></pre> <p>Once I've got my list data from somewhere, I copy it:</p> <pre><code>for(Map&lt;String,String&gt;map : vehicleinfo) { vehicleinfodisplay.add(map); } </code></pre> <p>and use a <code>SimpleAdapter</code> to display the display (copied) version of my data:</p> <pre><code>String[] from={"vehicle","dateon","dateoff","reg"}; int[] to={R.id.vehicle,R.id.vehicledateon,R.id.vehicledateoff,R.id.vehiclereg}; listadapter=new SimpleAdapter(c,vehicleinfodisplay,R.layout.vehiclelistrow,from,to); vehiclelist.setAdapter(listadapter); </code></pre> <p>Then I added a <code>TextWatcher</code> to the <code>EditText</code> which responds to an <code>afterTextChanged</code> event by clearing the display version of the list and then adding back only the items from the other list that meet the search criteria (in this case the "reg" field contains the search string). Once the display list is populated with the filtered list, I just call <code>notifyDataSetChanged</code> on the list's <code>SimpleAdapter</code>.</p> <pre><code>searchbox.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable s) { vehicleinfodisplay.clear(); String search=s.toString(); for(Map&lt;String,String&gt;map : vehicleinfo) { if(map.get("reg").toLowerCase().contains(search.toLowerCase())) vehicleinfodisplay.add(map); listadapter.notifyDataSetChanged(); } }; ... other overridden methods can go here ... }); </code></pre> <p>Hope this is helpful to someone.</p>

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).
