Remarks

Base class for Dialogs.

Note: Activities provide a facility to manage the creation, saving and restoring of dialogs. See Activity#onCreateDialog(int), Activity#onPrepareDialog(int, Dialog), Activity#showDialog(int), and Activity#dismissDialog(int). If these methods are used, #getOwnerActivity() will return the Activity that managed this dialog.

Often you will want to have a Dialog display on top of the current input method, because there is no reason for it to accept text. You can do this by setting the WindowManager.LayoutParams#FLAG_ALT_FOCUSABLE_IM WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM window flag (assuming your Dialog takes input focus, as it the default) with the following code:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                    WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);

FindViewById(Int32)	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()`).
FindViewById<T>(Int32)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
Hide()	Hide the dialog, but do not dismiss it.
InvalidateOptionsMenu()

NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
OnActionModeFinished(ActionMode)	To be added `Note that if you override this method you should always call through to the superclass implementation by calling super.`
OnActionModeStarted(ActionMode)	To be added `Note that if you override this method you should always call through to the superclass implementation by calling super.`
OnAttachedToWindow()	Called when the window has been attached to the window manager.
OnBackPressed()	Called when the dialog has detected the user's press of the back key.
OnContentChanged()	This hook is called whenever the content view of the screen changes (due to a call to M:Android.Views.Window.SetContentView(Android.Views.View,.LayoutParams) or AddContentView(View, ViewGroup+LayoutParams)).
OnContextItemSelected(IMenuItem)
OnContextMenuClosed(IMenu)
OnCreate(Bundle)	Similar to `Activity#onCreate`, you should initialize your dialog in this method, including calling `#setContentView`.
OnCreateContextMenu(IContextMenu, View, IContextMenuContextMenuInfo)	Called when the context menu for this view is being built.
OnCreateOptionsMenu(IMenu)	It is usually safe to proxy this call to the owner activity's `Activity#onCreateOptionsMenu(Menu)` if the client desires the same menu for this Dialog.
OnCreatePanelMenu(Int32, IMenu)	Initialize the contents of the menu for panel 'featureId'.
OnCreatePanelView(Int32)	Instantiate the view to display in the panel for 'featureId'.
OnDetachedFromWindow()	Called when the window has been attached to the window manager.

OnKeyDown(Keycode, KeyEvent)	A key was pressed down.
OnKeyLongPress(Keycode, KeyEvent)	Default implementation of `KeyEvent.Callback#onKeyLongPress(int, KeyEvent) KeyEvent.Callback.onKeyLongPress()`: always returns false (doesn't handle the event).
OnKeyMultiple(Keycode, Int32, KeyEvent)	Default implementation of `KeyEvent.Callback#onKeyMultiple(int, int, KeyEvent) KeyEvent.Callback.onKeyMultiple()`: always returns false (doesn't handle the event).
