SearchAutoCompleteTextView

public class SearchAutoCompleteTextView extends android.widget.AutoCompleteTextView
This class is not for the faint of heart. Home works in the pan & scan soft input mode. However, this mode gets rid of the soft keyboard on rotation, which is a probelm when the Search widget has focus. This special class changes Home's soft input method temporarily as long as the Search widget holds the focus. This way, the soft keyboard remains after rotation.
