    copied!<p>Looking at the part:</p> <pre><code>runOnUiThread(new Runnable() { </code></pre> <p>I have the problem:</p> <pre><code>The method runOnUiThread(new Runnable(){}) is undefined for the type new Thread(){} </code></pre> <p>So I understand that runOnUiThread must come from an activity. But Im not sure how this will be implemented? Its a dialog from within a Preference / settings view</p> <p>This where the ChannelsDialogPreference comes form: <strong>pref_channels.xml</strong></p> <pre><code>&lt;PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;com.example.tvrplayer.ChannelsDialogPreference android:title="@string/pref_channels_dialog_title" android:dialogMessage="@string/pref_channels_dialog_message" android:negativeButtonText="test"/&gt; &lt;/PreferenceScreen&gt; </code></pre> <p><strong>ChannelsDialogPreference:</strong></p> <pre><code>package com.example.tvrplayer; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; import android.app.Activity; import android.content.Context; import android.content.DialogInterface; import android.preference.DialogPreference; import android.util.AttributeSet; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.widget.AdapterView; import android.widget.ListView; public class ChannelsDialogPreference extends DialogPreference { public static Context ctx; // Activity activity; public ChannelsDialogPreference(Context context, AttributeSet attrs) { super(context, attrs); this.ctx = context; } @Override protected View onCreateDialogView() { // Set loading spinner // Start looking for channels // When complete, show channels LayoutInflater inflater = ((SettingsActivity) ctx).getLayoutInflater(); final View vw = inflater.inflate(R.layout.channel_content_view, null); // Do this in a new Thread Thread thread = new Thread() { @Override public void run() { try { final JSONArray channels; String username = null; String linkid = null; final String apiurl = "http://192.168.2.136:8080"; final String channelID = null; final DatabaseHandler db = new DatabaseHandler(ctx); List&lt;User&gt; users = db.getAllUsers(); for (User cn : users) { linkid = cn.getLinkID(); username = cn.getUserName(); } db.close(); final ArrayList&lt; HashMap &lt; String, String &gt; &gt; channelList = new ArrayList &lt; HashMap &lt; String, String &gt; &gt; (); try { if ( channelID != null ) { channels = Json.getJson(apiurl + "/rest/channel/"+ linkid +"/"+ username + "/" + channelID, "GET"); Log.i("CHANNELS", channels.toString()); for (int i=0; i &lt; channels.length(); i++) { JSONObject json_data = channels.getJSONObject(i); String name = json_data.getString("Name"); String channelid = json_data.getString("ChannelID"); HashMap&lt;String, String&gt; channelObject = new HashMap&lt;String, String&gt;(); // if ( json_data.getString("ParentPath") == "" ) { channelObject.put("id", channelid); channelObject.put("name", name); channelList.add(channelObject); // } } } else { channels = Json.getJson(apiurl + "/rest/channel/"+ linkid +"/"+ username, "GET"); Log.i("CHANNELS", channels.toString()); for (int i=0; i &lt; channels.length(); i++) { JSONObject json_data = channels.getJSONObject(i); String name = json_data.getString("Name"); String channelid = json_data.getString("ChannelID"); HashMap&lt;String, String&gt; channelObject = new HashMap&lt;String, String&gt;(); Log.i("CHANNEL LEN", ""+ json_data.getString("ParentID").length()); if ( json_data.getString("ParentID").length() &lt; 32 ) { channelObject.put("id", channelid); channelObject.put("name", name); channelList.add(channelObject); } } } runOnUiThread(new Runnable() { public void run() { HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(ctx, channelList); ListView lv = (ListView) vw.findViewById(R.id.list); lv.setAdapter(adapter); lv.isClickable(); lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1, int arg2, long arg3) { Log.i("CLICKED ON LV ITEM", "YEA"); } }); } }); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } catch (Exception e) { e.printStackTrace(); } } }; thread.start(); // new ChannelHandler().execute(apiurl, username, linkid, vw, ctx, channelID); return vw; } @Override protected void onDialogClosed(boolean positiveResult) { super.onDialogClosed(positiveResult); persistBoolean(positiveResult); } @Override public void onClick (DialogInterface dialog, int which) { super.onClick(dialog, which); // Log.v("which", Integer.toString(which)); // if(which == -1) { //Clear all // new ChannelHandler().execute(apiurl, username, linkid, vw, ctx, channelID); } } } </code></pre>
