  <p>is marking todolist_item.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;TodoListItemView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"

  <p>I pointed TodoListItemView, but that name does not work, there was an error opening the markup. There is an example in Java, as well, so there packages, all clear</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;com.paad.todolist.TodoListItemView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:padding="10dp"
  android:scrollbars="vertical"
  android:textColor="@color/notepad_text"
  android:fadingEdge="vertical"
  /&gt;
