Kotlin – How to Show a Toast in Android

🧠 Explanation:

• Toast.makeText() is used to display short messages to the user.
• The first parameter (this) is the Context — in an Activity, just use this; in a Fragment, use requireContext() or context.

• Toast.LENGTH_SHORT (about 2 seconds)
• Toast.LENGTH_LONG (about 3.5 seconds)

✅ Tips

• You can also use Toast(requireContext(), "Message", Toast.LENGTH_SHORT) in Fragments.
• For custom Toasts, you can inflate your own layout using LayoutInflater.
