Snackbar

This package is part of the Android support library which is no longer maintained. The support library has been superseded by AndroidX which is part of Jetpack. We recommend using the AndroidX libraries in all new projects. You should also consider migrating existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library class mappings.

Snackbars provide lightweight feedback about an operation. They show a brief message at the bottom of the screen on mobile and lower left on larger devices. Snackbars appear above all other elements on screen and only one can be displayed at a time.

They automatically disappear after a timeout or after user interaction elsewhere on the screen, particularly after interactions that summon a new surface or activity. Snackbars can be swiped off screen.

Snackbars can contain an action which is set via setAction(CharSequence, android.view.View.OnClickListener).

To be notified when a snackbar has been shown or dismissed, you can provide a Snackbar.Callback via addCallback(BaseCallback).

Public methods

make

added in version 22.2.0

Snackbar make (View view, 
                CharSequence text, 
                int duration)

Make a Snackbar to display a message

Snackbar will try and find a parent view to hold Snackbar's view from the value given to view. Snackbar will walk up the view tree trying to find a suitable parent, which is defined as a CoordinatorLayout or the window decor's content view, whichever comes first.

Having a CoordinatorLayout in your view hierarchy allows Snackbar to enable certain features, such as swipe-to-dismiss and automatically moving of widgets like FloatingActionButton.

Parameters
view	View: The view to find a parent from.
text	CharSequence: The text to show. Can be formatted text.
duration	int: How long to display the message. Either LENGTH_SHORT or LENGTH_LONG

Returns
Snackbar
