Where is the code that controls the reuse view in Android?

Question

Where is the source code that controls reuse Viewin Android? I can think of three different parts of this process, but maybe more:

• The logic that determines whether Viewto reuse
• Code that manages pools Viewthat can be reused
• Code that removes reusable Viewfrom the pool and resets its property values ​​to represent logically differentView

EDIT: Android App Development Blog post - gotchas and quirks give the following example:

public class PencilWise extends ListActivity {
    View activeElement;
    // ...
    @Override
    public void onCreate ( Bundle savedInstanceState ) {
        // ...
        this.getListView( ).setOnItemClickListener ( new OnItemClickListener ( ) {
            public void onItemClick ( AdapterView<?> parent, View view, int position, long id ) {
                MyActivity.this.activeElement = view;
                MyActivity.this.showDialog ( DIALOG_ANSWER );
            }
        } );
    }
}

showDialog , , . , , onItemClick, , activeElement , , !
