Public methods

requireViewById

public static View requireViewById (Dialog dialog, 
                int id)

Finds the first descendant view with the given ID or throws an IllegalArgumentException if the ID is invalid (< 0), there is no matching view in the hierarchy, or the dialog has not yet been fully created (for example, via Dialog.show() or Dialog.create()).

Note: In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.

Parameters
`dialog`	`Dialog`: the Dialog to search the View in
`id`	`int`: the ID to search for

Returns
`View`	a view with given ID
