How to send String values from one activity to another through intent?

How do I send values that the user puts in editText in StartActivity to textView3 in Second Activity? I am essentially asking the user for his name in StartActivity and then printing "Your name is ___" in the SecondActivity.

I did try to use and then in the SecondActivity but it shows null what do I do?

StartActivity::

    button.setOnClickListener 
    {
        val name = editText.text.toString()
        val intent2 = Intent (this, SecondActivity::class.java)

        intent.putExtra("name", name)
        startActivity(intent2)

    }

SecondActivity::

    override fun onCreate(savedInstanceState: Bundle?) 
    {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_second)

      val name2 = intent.getStringExtra("name")
      textView3.text = name2
    }

The error was that it prints "Your name is null".enter code here

Change intent.putExtra("name", name) to intent2.putExtra("name", name)

Note: Whenever you don't have a variable intent in your scope. Kotlin extensions take intent value from getIntent() which is your previous intent. And that's why you have missed the compilation error.

This looks like a typo that Kotlin is helping you make. The name of the intent you're starting is intent2, but you're adding the "name" string to intent. This is possible because Kotlin is letting you access the results of getIntent() (i.e. the Intent object used to launch the current activity) as though it were a property.

Change this line to use intent2 and it should all start working:

intent2.putExtra("name", name)
