[Tutorial] How To Display a Toast Message From Android Fragment

Hello dear readers and developers,

This is going to be a short but informative tutorial, here we are going to show a toast message from android fragments. You may think showing toast message is easy what is there to learn about but you can easily toast a message in android from activity but it requires one more step to show toast message in the android fragment

If you want to learn how to show toast message in your android application you can follow the below tutorial


Now that you have learned about how to show an android toast message from activity its time to learn how to show a toast message from the android fragment.

For creating a fragment you can follow our beginner's guide on android-fragments with kotlin here, once you learned that create a fragment and add a simple button to it.

fragment_blank.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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"
    android:background="@color/firstFragment"
    tools:context=".BlankFragment">

     <Button
        android:id="@+id/toastButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/go_to_button"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

 </androidx.constraintlayout.widget.ConstraintLayout>

In case you missed:


Once you have created a layout now head to the BlankFragment.kt file and add this toast code inside your buttons onclick listener


Toast.makeText(requireContext(),"Toasting from fragment",Toast.LENGTH_LONG).show()


As you can see this is our usual code to show a toast message in android, but with a little change, which is the first parameter which is the applicationContext which we need to pass, but in a fragment, we can actually access the applicationContext because it was added to an activity, so to show toast message inside a fragment we need the context which we can get by calling either of two functions context and requireContext .

And if you still think android not showing the toast message make sure you called .show() method at the end.

In case you missed
In general, context might return null, which is not good for our code so we use requireContext() which will return not return null at any point instead it will throw an exception in case if the value is null. So it is safe to use well you might need a try-catch if you think the value could be null.

And here is the short video of the output
