Add a Snackbarsuggest change
One of the main features in Material Design is the addition of a
Snackbar, which in theory replaces the previous
Toast. As per the Android documentation:
Snackbars contain a single line of text directly related to the operation performed. They may contain a text action, but no icons. Toasts are primarily used for system messaging. They also display at the bottom of the screen, but may not be swiped off-screen.
Toasts can still be used in Android to display messages to users, however if you have decided to opt for material design usage in your app, it is recommended that you actually use a snackbar. Instead of being displayed as an overlay on your screen, a
Snackbar pops from the bottom.
Here is how it is done:
Snackbar snackbar = Snackbar .make(coordinatorLayout, "Here is your new Snackbar", Snackbar.LENGTH_LONG); snackbar.show();
As for the length of time to show the
Snackbar, we have the options similar to the ones offered by a
Toast or we could set a custom duration in milliseconds:
You can also add dynamic features to your
Snackbar such as
ActionCallback or custom color. However do pay attention to the design guideline offered by Android when customising a
Snackbar has one limitation however. The parent layout of the view you are going to implement a
Snackbar in needs to be a
CoordinatorLayout. This is so that the actual popup from the bottom can be made.
This is how to define a
CoordinatorLayout in your layout xml file:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coordinatorLayout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> //any other widgets in your layout go here. </android.support.design.widget.CoordinatorLayout>
CoordinatorLayout then needs to be defined in your Activity’s
onCreate method, and then used when creating the
