    <p>I have an Activity with an AutoComplete box on it. Whenever the text changes, I want to call a web service and populate the ArrayAdapter with the new String[] returned. This part all works great, except the list in the UI isn't being refreshed when there are all new values in String[] schools. The original list populated in my onCreate always remains. </p> <p>I read somewhere I needed to update it on the same thread the UI is running on, so I tried the Runnable listed in my code below. But that, as well as just updating my class variable schools does not work alongside notifyOnDataSetChange()</p> <p>Where am I going wrong?</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); schools = SchoolProxy.search("Co"); autoCompleteAdapter = new ArrayAdapter(this,android.R.layout.simple_dropdown_item_1line, schools); autoComplete = (AutoCompleteTextView) findViewById(R.id.edit); autoComplete.addTextChangedListener(textChecker); autoComplete.setAdapter(autoCompleteAdapter); } ... .... ... final TextWatcher textChecker = new TextWatcher() { public void afterTextChanged(Editable s) {} public void beforeTextChanged(CharSequence s, int start, int count, int after) {} public void onTextChanged(CharSequence s, int start, int before, int count) { schools = SchoolProxy.search(s.toString()); runOnUiThread(updateAdapter); } }; private Runnable updateAdapter = new Runnable() { public void run() { autoCompleteAdapter.notifyDataSetChanged(); } }; </code></pre> <p>As a less important side note, if each item in schools has a name \n city,state. Is it possible to have the city &amp; state on a second line within the auto drop down box? Just for formatting purposes. Would look cleaner if I could. </p> <p>Thank you!</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.
