Since Android Studio 4.1 the Snackbar
is in a new style (from the built-in Material library):
But I still prefer the old style:
How to achieve that? I've searched around the internet but still can't find the answer.
Snackbars can span the entire width of the screen only when a UI does not use persistent navigation components like app bars or bottom navigation bars. Snackbars that span the entire width of a UI can push only FABs up when they appear.
Since I don't have your code you can try setting the style of Snackbar
by adding this line in your AppTheme in styles.xml or themes.xml:
<item name="snackbarStyle">@style/Widget.MaterialComponents.Snackbar.FullWidth</item>
Or programmatically you can try this:
// Create the Snackbar
Snackbar snackbar = Snackbar.make(containerLayout, "", Snackbar.LENGTH_LONG);
// Get the Snackbar's layout view
Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
//If the view is not covering the whole snackbar layout, add this line
layout.setPadding(0,0,0,0);
// Show the Snackbar
snackbar.show();
