Constructors

ReactiveActivity()

Initializes a new instance of the ReactiveActivity class.

protected ReactiveActivity()

ReactiveActivity(IntPtr, JniHandleOwnership)

Initializes a new instance of the ReactiveActivity class.

protected ReactiveActivity(IntPtr handle, JniHandleOwnership ownership)

Parameters

handle IntPtr

The handle.

ownership JniHandleOwnership

The ownership.

Properties

Activated

Gets a signal when the activity is activated.

public IObservable<Unit> Activated { get; }

Property Value

IObservable<Unit>

ActivityResult

Gets the activity result.

public IObservable<(int, Result, Intent)> ActivityResult { get; }

Property Value

IObservable<(int, Result, Intent)>

The activity result.

Changed

Gets an Observable that fires after a property has changed. Note that this should not fire duplicate change notifications if a property is set to the same value multiple times.

public IObservable<IReactivePropertyChangedEventArgs<ReactiveActivity>> Changed { get; }

Property Value

IObservable<IReactivePropertyChangedEventArgs<ReactiveActivity>>

Changing

Gets an observable that fires before a property is about to be changed. Note that this should not fire duplicate change notifications if a property is set to the same value multiple times.

public IObservable<IReactivePropertyChangedEventArgs<ReactiveActivity>> Changing { get; }

Property Value

IObservable<IReactivePropertyChangedEventArgs<ReactiveActivity>>

Deactivated

Gets a signal when the activity is deactivated.

public IObservable<Unit> Deactivated { get; }

Property Value

IObservable<Unit>

ThrownExceptions

Gets a observable which will fire whenever an exception would normally terminate ReactiveUI internal state.

public IObservable<Exception> ThrownExceptions { get; }

Property Value

IObservable<Exception>

Methods

Dispose(bool) 

protected override void Dispose(bool disposing)

Parameters

disposing bool

OnActivityResult(int, Result?, Intent?) 

protected override void OnActivityResult(int requestCode, Result? resultCode, Intent? data)

Parameters

requestCode int
resultCode Result
data Intent

OnPause() 

protected override void OnPause()

OnResume() 

protected override void OnResume()

StartActivityForResultAsync(Intent?, int)

Starts the activity for result asynchronously.

public Task<(Result, Intent)> StartActivityForResultAsync(Intent? intent, int requestCode)

Parameters

intent Intent

The intent.

requestCode int

The request code.

Returns

Task<(Result, Intent)>

A task with the result and the intent.

StartActivityForResultAsync(Type, int)

Starts the activity for result asynchronously.

public Task<(Result, Intent)> StartActivityForResultAsync(Type type, int requestCode)

Parameters

type Type

The type.

requestCode int

The request code.

Returns

Task<(Result, Intent)>

A task with the result and intent.

SuppressChangeNotifications()

When this method is called, an object will not fire change notifications (neither traditional nor Observable notifications) until the return value is disposed.

public IDisposable SuppressChangeNotifications()

Returns

IDisposable

An object that, when disposed, reenables change notifications.

Events

PropertyChanged 

public event PropertyChangedEventHandler? PropertyChanged

Event Type

PropertyChangedEventHandler

PropertyChanging 

public event PropertyChangingEventHandler? PropertyChanging

Event Type

PropertyChangingEventHandler
