    copied!<p>I'm using a custom ArrayAdapter to set the adapter on an AutocompleteTextView (AddressAdapter extends ArrayAdapter).</p> <pre><code>public class AutoCompleteAdapter extends ArrayAdapter&lt;String&gt; implements Filterable { private ArrayList&lt;String&gt; mData; ArrayList&lt;String&gt; listTempPrefix = new ArrayList&lt;String&gt;(); ArrayList&lt;String&gt; listTemp = new ArrayList&lt;String&gt;(); String valueText; String[] words; String ulcase; public AutoCompleteAdapter(Context context, int textViewResourceId, ArrayList&lt;String&gt; bS) { super(context, textViewResourceId); mData = bS;//new ArrayList&lt;String&gt;(); } @Override public int getCount() { synchronized (listTempPrefix) { return listTempPrefix.size(); } } @Override public String getItem(int index) { synchronized (listTempPrefix) { try { //Log.e("Error", listTempPrefix.get(index)); return listTempPrefix.get(index); } catch(IndexOutOfBoundsException e) { Log.e("Error", "IndexOutOfBoundsException"); return ""; } } } @Override public Filter getFilter() { Filter myFilter = new Filter() { @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults filterResults = new FilterResults(); synchronized (filterResults) { listTempPrefix.clear(); listTemp.clear(); //Log.e("1", "1"); try { if(constraint != null) { // A class that queries a web API, parses the data and returns an ArrayList&lt;Style&gt; //StyleFetcher fetcher = new StyleFetcher(); //try { //mData = fetcher.retrieveResults(constraint.toString()); //} //catch(Exception e) {} // Now assign the values and count to the FilterResults object for(String value: mData) { valueText = value.toLowerCase(); //System.out.println("constraintH - " + constraint); constraint.toString().toLowerCase(); ulcase = constraint.toString().toLowerCase(); //System.out.println("ulcase - " + ulcase); if (valueText.startsWith(ulcase)) { listTempPrefix.add(value); } else { words = valueText.split(" "); //final int wordCount = words.length; // Start at index 0, in case valueText starts with space(s) for (int k = 0; k &lt; words.length; k++) { if (words[k].startsWith(ulcase)) { listTemp.add(value); break; } } } ///listTemp.add(mData.get(i)); //filterResults.count = mData.size(); // System.out.println("mData" + i + mData.get(i)); } //Log.e("2", "2"); // System.out.println("size " + listTemp.size() + " value" + listTemp); listTempPrefix.addAll(listTemp); filterResults.values = listTempPrefix; filterResults.count = listTempPrefix.size(); //System.out.println("size " + filterResults.count + " value" + filterResults.values); //System.out.println("constraint" + constraint); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return filterResults; } } @Override protected void publishResults(CharSequence contraint, FilterResults filterResults) { synchronized (filterResults) { if(filterResults != null &amp;&amp; filterResults.count &gt; 0) { notifyDataSetChanged(); //Log.e("notifyDataSetChanged", "notifyDataSetChanged"); } else { notifyDataSetInvalidated(); //Log.e("notifyDataSetInvalidated", "notifyDataSetInvalidated"); } } } }; return myFilter; } </code></pre> <p>}</p> <p>What I got sometimes: please notice, it happens really rarely. But I'd like to get rid of this bug completely. Here is partial stacktrace:</p> <pre><code>java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ListView(-1, class android.widget.AutoCompleteTextView$DropDownListView) with Adapter(class com.example.test.AutoCompleteAdapter)]. </code></pre> <p>The problem maybe that the fast input from keybord, method notifyDataSetChanged () issn't call. But i'am not sure. </p>
