setWidgetLayoutResource
Sets the layout for the controllable widget portion of this preference. This is inflated into the main layout. For example, a CheckBoxPreference would specify a custom layout (consisting of just the CheckBox) here, instead of creating its own main layout.
It is an error to change the layout after adding the preference to a PreferenceGroup.
Parameters
widgetLayoutResId
The layout resource ID to be inflated into the main layout
