`AppCompatDialogFragment(contentLayoutId: @LayoutRes Int)`

Public functions
`Dialog`	`onCreateDialog(savedInstanceState: Bundle?)` Override to build your own custom Dialog container.

Inherited Constants

From androidx.fragment.app.DialogFragment

`const Int`	`STYLE_NORMAL = 0` Style for `setStyle`: a basic, normal dialog.
`const Int`	`STYLE_NO_FRAME = 2` Style for `setStyle`: don't draw any frame at all; the view hierarchy returned by `onCreateView` is entirely responsible for drawing the dialog.
`const Int`	`STYLE_NO_INPUT = 3` Style for `setStyle`: like `STYLE_NO_FRAME`, but also disables all input to the dialog.
`const Int`	`STYLE_NO_TITLE = 1` Style for `setStyle`: don't include a title area.

Public functions

onCreateDialog

fun onCreateDialog(savedInstanceState: Bundle?): Dialog

Override to build your own custom Dialog container. This is typically used to show an AlertDialog instead of a generic Dialog; when doing so, onCreateView does not need to be implemented since the AlertDialog takes care of its own content.

This method will be called after onCreate and immediately before onCreateView. The default implementation simply instantiates and returns a Dialog class.

Note: DialogFragment own the Dialog.setOnCancelListener and Dialog.setOnDismissListener callbacks. You must not set them yourself. To find out about these events, override onCancel and onDismiss.

Parameters
`savedInstanceState: Bundle?`	The last saved instance state of the Fragment, or null if this is a freshly created Fragment.

Returns
`Dialog`	Return a new Dialog instance to be displayed by the Fragment.
