Answer for first question: You could pass the position of the item to the new activity with intent.putExtra().

Activity 1 Intent intent = new Intent(this, Shima.class); intent.putExtra("position_value", position); startActivity(intent); Activity 2 Intent intent = getIntent(); int position = intent.getIntExtra("position_value", 0); // 0 is the default value // set a layout based on position with switch case or if... switch (position){ case 1: setContentView(R.layout.activity_card_one); break; case
