    <p>To display your activities' names correctly in the list, you should override the <code>getView</code> method of your <code>ListAdapter</code>, and set some of your local variables as final (to work with inner class):</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final PackageManager pm = this.getPackageManager(); Intent intent = new Intent(Intent.ACTION_MAIN, null); intent.addCategory(Intent.CATEGORY_LAUNCHER); final ArrayList&lt;ResolveInfo&gt; list = (ArrayList&lt;ResolveInfo&gt;) pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED); for (ResolveInfo rInfo : list) { Log.i(TAG, ": Installed Applications " + rInfo.activityInfo. applicationInfo.loadLabel(pm).toString()); } final ArrayAdapter&lt;ResolveInfo&gt; adapter = new ArrayAdapter&lt;ResolveInfo&gt;(this, R.layout.list_item, list) { @Override public View getView(int position, View convertView, ViewGroup parent) { convertView = super.getView(position, convertView, parent); final String text = list.get(position).activityInfo. applicationInfo.loadLabel(pm).toString(); ((TextView)convertView).setText(text); return convertView; } }; setListAdapter(adapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); } </code></pre> <p>This way you have your custom <code>ArrayAdapter</code> implementation, which displays the proper label of applicationinfo in the <code>TextView</code>.</p> <p>You can also achieve this, if you create a new <code>ArrayList&lt;String&gt;</code>, and populate it inside the for cycle where you log the applications: </p> <pre><code>final ArrayList&lt;String&gt; labelList = new ArrayList&lt;String&gt;(); for (ResolveInfo rInfo : list) { Log.i(TAG, ": Installed Applications " + rInfo.activityInfo. applicationInfo.loadLabel(pm).toString()); labelList.add(rInfo.activityInfo. applicationInfo.loadLabel(pm).toString()); } final ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this, R.layout.list_item, labelList); setListAdapter(adapter); </code></pre> <p>Then you use this new <code>labelList</code> as the source of your <code>adapter</code>.</p> <p><strong>Update</strong><br /> To include the icon into the item renderers, the overridden <code>getView</code> method would look like:</p> <pre><code>@Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) convertView = LayoutInflater.from(parent.getContext()). inflate(R.layout.list_item, parent, false); final String text = list.get(position).activityInfo. applicationInfo.loadLabel(pm).toString(); ((TextView)convertView.findViewById(R.id.text)).setText(text); final Drawable drawable = list.get(position).activityInfo.applicationInfo.loadIcon(pm); ((ImageView)convertView.findViewById(R.id.image)).setImageDrawable(drawable); return convertView; } </code></pre> <p>and your <code>res/layout/list_item.xml</code> layout file has to contain the <strong><code>text</code></strong> <code>TextView</code> and the <strong><code>image</code></strong> <code>ImageView</code>: </p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;ImageView android:id="@+id/image" android:layout_width="50dp" android:layout_height="50dp" /&gt; &lt;TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" android:textSize="16sp" /&gt; &lt;/LinearLayout&gt; </code></pre>

    2. COeither `Ctrl + Space` after them, or just add the necessary imports manually: `import android.view.ViewGroup;` and `import android.widget.TextView;` at the top of your class.

    3. COThanks so much... I don't know why Eclipse didn't suggest importing them.... odd. I am probably asking too much here, but do you know of an easy way to include the app's icon in the listview?

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.

SQuiL has stopped working due to an internal error.

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