    private void switchActivities() {

        startActivity(ActivityIntent);

    }

}

You need to pass the data using the ActivityIntent you have created in switchActivity function amd then get that data in your second Activity from getIntent().getString(key) function.

Please refer to this, How do I pass data between Activities in Android application?

thank you @ganeshraj020794 i will try using intent.putExtra to pass data to other activity but the problem is onClickListner doesnt do nothing :( – Kamal Fach Jun 30 '21 at 18:55
@KamalFach First of all, make sure all the views are being correctly initialized (All the id names are matching correctly), Second try to debug the onClick method and see if it gets called properly or if its failing inside – Ofek Jun 30 '21 at 19:47
