android get positon of itemclicked in another class

Question

Can someone please help me? I am trying to access a "position" variable itemclicked. I want the content of the other class to display a different thing depending on the list I clicked.

What I want is this: if I click position 0, then it takes me to another page and the TextView I created on that class changes to "you clicked position 0". If I click position 1, it changes to "you clicked position 1", etc.

I've attempted to do this, but it only works when I click position 0. If I click item 1, it shows "you have clicked position 0". I am very confused. I have tried using putexraa and other methods, but they are not working. Your help would be greatly appreciated.

Answer 1

Pass the value of man in putExtra while setting the intent for that class in mainActivity

   Class ourClass = Class.forName("com.obi.arinzeapp.Music");
   Intent ourIntent = new Intent(MainActivity.this, ourClass);
   ourIntent.putExtra("man",man);
   startActivity(ourIntent);

And get this extra in Music Activity

   extras = getIntent().getExtras();
   newInt= extras.getInt("man");

This is the standard way to pass the values from one activity to another. But the way you doing you can try making man as static variablebut it is not recommended.
