Correct.
If you look in res/layout/lunar_layout.xml, you will see the declaration:
<com.example.android.lunarlander.LunarView
android:id="@+id/lunar"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
When the layout is inflated via setContentView(), the constructors for
each widget and container are called. For built-in widgets like
FrameLayout, Android knows they are in the package android.widget; for
custom ones, the full namespace is spelled out in the layout
(com.example.android.lunarlander.LunarView).
