Android Naming Layout Scheme
<p>I have a piece of code </p>

<pre><code>public class Radio_groupActivity extends ListActivity {
TextView selection;
String[] items={"One", "Two", "Three"};

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    setListAdapter(new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1));

}
</code></pre>

<p>}</p>

<p>Now I have the main.xml in the folder but I don't have any xml file called simple_list_item_1</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="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
&gt;


&lt;TextView  
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:id="@+id/selection"
/&gt;


&lt;ListView android:layout_height="fill_parent"
android:id="@+id/list" 
android:layout_width="fill_parent"&gt;&lt;/ListView&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>So, what's the relationship of the listview with @id/list and that android.R.layout.simple_list_item_1?</p>
