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.

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

Snackbars automatically disappear after a timeout. They can also be dismissed by being swiped off screen, by action click, from a new snackbar being displayed, or manually via a call to dismiss().

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

For more information, see the component developer guidance and design guidelines.

Public methods

dismiss

public void dismiss ()

Dismiss the BaseTransientBottomBar.

getDuration

public int getDuration ()

Return the duration.

Returns
int

isShown

public boolean isShown ()

Return whether this BaseTransientBottomBar is currently being shown.

Returns

make

public static 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.

Parameters
view	View: The view to find a parent from. This view is also used to find the anchor view when calling BaseTransientBottomBar.setAnchorView(int).
text	CharSequence: The text to show. Can be formatted text.
duration	int: How long to display the message. Can be BaseTransientBottomBar.LENGTH_SHORT, BaseTransientBottomBar.LENGTH_LONG, BaseTransientBottomBar.LENGTH_INDEFINITE, or a custom duration in milliseconds.

Returns
Snackbar

                View view,
