I am running into some issues with displaying a snackbar inside a fragment. I can set one up fine for an activity but when I try in a fragment it just doesnt appear and no error is given.
Snackbar inside fragment
Snackbar snackbar = Snackbar.make(rootView, "Snackbar test", Snackbar.LENGTH_SHORT);
View sbView = snackbar.getView();
TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(Color.YELLOW);
snackbar.show();
rootView in fragment
rootView = inflater.inflate(R.layout.fragment_possible_recipes, container, false);

try this way
You pass a View
that is not a CoordinatorLayout
the Snackbar
will walk up the tree until it finds a CoordinatorLayout
or the root of the layout.
rootlayout = (CoordinatorLayout) rootView.findViewById(R.id.coordinatorLayout);
and Snackbar
Snackbar snackbar = Snackbar.make(rootlayout , "Snackbar test", Snackbar.LENGTH_SHORT);
View sbView = snackbar.getView();
TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(Color.YELLOW);
snackbar.show();
You can get it done far easily just by using it like following.
Snackbar.make(getActivity().findViewById(android.R.id.content),
"text to show", Snackbar.LENGTH_LONG).show();
This should work in anywhere within a Fragment.
PS. I know this is old but I leave it here anyway for future reference.
I had a problem just like yours. The way i got the snackbar to appear was by adding the code below to the onCreateView method of the fragment in question:
Snackbar.make(rootView,"Snack bar!", Snackbar.LENGTH_SHORT)
.show();
Remember to make sure the layout of the fragment in question is a Coordinator Layout.
Snackbar.make(requireActivity().findViewById(R.id.constraintLayout),"your message", Snackbar.LENGTH_LONG)
.show();
android:id="@+id/constraintLayout"
<androidx.constraintlayout.widget.ConstraintLayout
android:id="@+id/constraintLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".YourFragment">
In fragment you can put Snackbar this way, by putting container
Snackbar snackbar = Snackbar.make(container, "I am Snackbar", Snackbar.LENGTH_LONG);
snackbar.show();
