Inherited methods

From class


        
          android.app.Dialog

`void`	`addContentView(View view, ViewGroup.LayoutParams params)` Add an additional content view to the screen.
`void`	`cancel()` Cancel the dialog.
`void`	`closeOptionsMenu()`
`void`	`create()` Forces immediate creation of the dialog.
`void`	`dismiss()` Dismiss this dialog, removing it from the screen.
`boolean`	`dispatchGenericMotionEvent(MotionEvent ev)` Called to process generic motion events.
`boolean`	`dispatchKeyEvent(KeyEvent event)` Called to process key events.
`boolean`	`dispatchKeyShortcutEvent(KeyEvent event)` Called to process a key shortcut event.

`boolean`	`dispatchTouchEvent(MotionEvent ev)` Called to process touch screen events.
`boolean`	`dispatchTrackballEvent(MotionEvent ev)` Called to process trackball events.
`<T extends View> T`	`findViewById(int id)` Finds the first descendant view with the given ID or `null` 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()`).
`ActionBar`	`getActionBar()` Retrieve the `ActionBar` attached to this dialog, if present.
`final Context`	`getContext()` Retrieve the Context this Dialog is running in.
`View`	`getCurrentFocus()` Call `Window.getCurrentFocus()` on the Window if this Activity to return the currently focused view.
`LayoutInflater`	`getLayoutInflater()`
`OnBackInvokedDispatcher`	`getOnBackInvokedDispatcher()` Returns the `OnBackInvokedDispatcher` instance associated with the window that this dialog is attached to.
`final Activity`	`getOwnerActivity()` Returns the Activity that owns this Dialog.
`final SearchEvent`	`getSearchEvent()` During the onSearchRequested() callbacks, this function will return the `SearchEvent` that triggered the callback, if it exists.
`final int`	`getVolumeControlStream()`
`Window`	`getWindow()` Retrieve the current Window for the activity.
`void`	`hide()` Hide the dialog, but do not dismiss it.
`void`	`invalidateOptionsMenu()`
`boolean`	`isShowing()`
`void`	`onActionModeFinished(ActionMode mode)` Called when an action mode has been finished. Note that if you override this method you should always call through to the superclass implementation by calling super.onActionModeFinished(mode).
`void`	`onActionModeStarted(ActionMode mode)` Called when an action mode has been started. Note that if you override this method you should always call through to the superclass implementation by calling super.onActionModeStarted(mode).

`void`	`onBackPressed()` This method was deprecated in API level 33. Use `OnBackInvokedCallback` or `androidx.activity.OnBackPressedCallback` to handle back navigation instead. Starting from Android 13 (API level 33), back event handling is moving to an ahead-of-time model and `onBackPressed()` and `KeyEvent#KEYCODE_BACK` should not be used to handle back events (back gesture or back button click). Instead, an `OnBackInvokedCallback` should be registered using `Dialog#getOnBackInvokedDispatcher()` `.registerOnBackInvokedCallback(priority, callback)`.
