    In your Main Activity:
    Please call intent.putExtra(), before startActivity(). Example:

    val intent = Intent(this, NewActivity::class.java) 
intent.putExtra("username","Name")
startActivity(intent)

    And fetch like that (in Main Activity 2)

    val bundle :Bundle?=intent.extras 
if (bundle!=null){ 
val user_name = bundle.getString("username") 
}

    I noticed that in the ‘MainActivity.java‘ you are starting new activity before passing the string into the intent,
    just switch the both lines 30 and 31.

    In your MainActivity, you should putExtra before startActivity. Like this:

        Intent intent = new Intent(...);
    intent.putExtra...;
    startActivity(intent);

    In your MainActivity, create a new Intent:

    String name="abcdef;
Intent i = new Intent(MainActivity.this, MainActivity2.class);    
i.putExtra("key",name);
startActivity(i);

    Then in the MainActivity2, retrieve those values:

    Bundle extras = getIntent().getExtras();
if (extras != null) {
    String name = extras.getString("key");
    //"key" must match that used in the other activity
}
