DialogCompat

Kotlin |Java

public class DialogCompat

Helper for accessing features in android.app.Dialog in a backwards compatible fashion.

Summary

Public methods
`static @NonNull View`	`requireViewById(@NonNull 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 `show` or `create`).

Public methods

requireViewById

public static @NonNull View requireViewById(@NonNull 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 show or 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
`@NonNull Dialog dialog`	the Dialog to search the View in
`int id`	the ID to search for

Returns
`@NonNull View`	a view with given ID
