AndroidWidgetBuilder is the default WidgetBuilder for AndroidMetawidget. It instantiates the following widgets for the following Metawidget attributes:

Widget		Metawidget Attribute
android.widget
	CheckBox	type="boolean" (and type="java.lang.Boolean" when also required)
	DatePicker	type="java.utils.Date" when also required
	EditText	type of primitive wrapper (e.g. Integer or Float) except java.lang.Boolean. Also if property is of unknown type but dont-expand. If large, calls setMinLines. If masked, sets a PasswordTransformationMethod. If numeric, sets a DigitsKeyListener. If maximum-length, sets a InputFilter.LengthFilter. If type is a Date, sets a DateKeyListener
	PasswordTextBox	masked (except when also read-only)
	Spinner	lookup
org.metawidget.gwt.client.ui
	Stub	hidden

OverriddenWidgetBuilder locates child widgets designed to override default generation. It matches Views whose tag equals the same tag Metawidget would have generated.

ReadOnlyWidgetBuilder returns read-only widgets when either the business property is read-only or the Metawidget has setReadOnly. It instantiates the following widgets for the following Metawidget attributes:

Widget		Metawidget Attribute
android.widget
	TextView	read-only (except when also type="java.util.Collection"). If masked sets View.INVISIBLE
org.metawidget.gwt.client.ui
	Stub	action when also read-only, masked when also read-only, type="java.util.Collection" when also read-only
