/**
* An activity that displays a list of items by binding to a data source such as
* an array or Cursor, and exposes event handlers when the user selects an item.
* <p>
* ListActivity hosts a {@link android.widget.ListView ListView} object that can
* be bound to different data sources, typically either an array or a Cursor
* holding query results. Binding, screen layout, and row layout are discussed
* in the following sections.
* <p>
* <strong>Screen Layout</strong>
* </p>
* <p>
* ListActivity has a default layout that consists of a single, full-screen list
* in the center of the screen. However, if you desire, you can customize the
* screen layout by setting your own view layout with setContentView() in
* onCreate(). To do this, your own view MUST contain a ListView object with the
* id "@android:id/list" (or {@link android.R.id#list} if it's in code)
* <p>
* Optionally, your custom view can contain another view object of any type to
* display when the list view is empty. This "empty list" notifier must have an
* id "android:id/empty". Note that when an empty view is present, the list view
* will be hidden when there is no data to display.
* <p>
* The following code demonstrates an (ugly) custom screen layout. It has a list
* with a green background, and an alternate red "no data" message.
* </p>
*
* <pre>
* &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
* &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
* android:orientation=&quot;vertical&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;match_parent&quot;
* android:paddingLeft=&quot;8dp&quot;
* android:paddingRight=&quot;8dp&quot;&gt;
*
* &lt;ListView android:id=&quot;@android:id/list&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;match_parent&quot;
* android:background=&quot;#00FF00&quot;
* android:layout_weight=&quot;1&quot;
* android:drawSelectorOnTop=&quot;false&quot;/&gt;
*
* &lt;TextView android:id=&quot;@android:id/empty&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;match_parent&quot;
* android:background=&quot;#FF0000&quot;
* android:text=&quot;No data&quot;/&gt;
* &lt;/LinearLayout&gt;
* </pre>
*
* <p>
* <strong>Row Layout</strong>
* </p>
* <p>
* You can specify the layout of individual rows in the list. You do this by
* specifying a layout resource in the ListAdapter object hosted by the activity
* (the ListAdapter binds the ListView to the data; more on this later).
* <p>
* A ListAdapter constructor takes a parameter that specifies a layout resource
* for each row. It also has two additional parameters that let you specify
* which data field to associate with which object in the row layout resource.
* These two parameters are typically parallel arrays.
* </p>
* <p>
* Android provides some standard row layout resources. These are in the
* {@link android.R.layout} class, and have names such as simple_list_item_1,
* simple_list_item_2, and two_line_list_item. The following layout XML is the
* source for the resource two_line_list_item, which displays two data
* fields,one above the other, for each list row.
* </p>
*
* <pre>
* &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
* &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;wrap_content&quot;
* android:orientation=&quot;vertical&quot;&gt;
*
* &lt;TextView android:id=&quot;@+id/text1&quot;
* android:textSize=&quot;16sp&quot;
* android:textStyle=&quot;bold&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;wrap_content&quot;/&gt;
*
* &lt;TextView android:id=&quot;@+id/text2&quot;
* android:textSize=&quot;16sp&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;wrap_content&quot;/&gt;
* &lt;/LinearLayout&gt;
* </pre>
*
* <p>
* You must identify the data bound to each TextView object in this layout. The
* syntax for this is discussed in the next section.
* </p>
* <p>
* <strong>Binding to Data</strong>
* </p>
* <p>
* You bind the ListActivity's ListView object to data using a class that
* implements the {@link android.widget.ListAdapter ListAdapter} interface.
* Android provides two standard list adapters:
* {@link android.widget.SimpleAdapter SimpleAdapter} for static data (Maps),
* and {@link android.widget.SimpleCursorAdapter SimpleCursorAdapter} for Cursor
* query results.
* </p>
* <p>
* The following code from a custom ListActivity demonstrates querying the
* Contacts provider for all contacts, then binding the Name and Company fields
* to a two line row layout in the activity's ListView.
* </p>
*
* <pre>
* public class MyListAdapter extends ListActivity {
*
* &#064;Override
* protected void onCreate(Bundle savedInstanceState){
* super.onCreate(savedInstanceState);
*
* // We'll define a custom screen layout here (the one shown above), but
* // typically, you could just use the standard ListActivity layout.
* setContentView(R.layout.custom_list_activity_view);
*
* // Query for all people contacts using the {@link android.provider.Contacts.People} convenience class.
* // Put a managed wrapper around the retrieved cursor so we don't have to worry about
* // requerying or closing it as the activity changes state.
* mCursor = this.getContentResolver().query(People.CONTENT_URI, null, null, null, null);
* startManagingCursor(mCursor);
*
* // Now create a new list adapter bound to the cursor.
* // SimpleListAdapter is designed for binding to a Cursor.
* ListAdapter adapter = new SimpleCursorAdapter(
* this, // Context.
* android.R.layout.two_line_list_item, // Specify the row template to use (here, two columns bound to the two retrieved cursor
* rows).
* mCursor, // Pass in the cursor to bind to.
* new String[] {People.NAME, People.COMPANY}, // Array of cursor columns to bind to.
* new int[] {android.R.id.text1, android.R.id.text2}); // Parallel array of which template objects to bind to those columns.
*
* // Bind to our new adapter.
* setListAdapter(adapter);
* }
* }
* </pre>

* @see android.widget.ListView
