List Restaurant Dishes Restaurant 1 Dishes Restaurant 2 Price Restaurant 1 Price 2 Restaurant

Within my Activity I put two Spinners one that will get the Array List Restaurants and the other the I want to appear the data of the Array list when I select the restaurant and in the end I would pick up and setaria as a Text View of the price .

You can populate according to the spinner dishes according to the restaurant spinner selection through the setOnItemSelectedListener.

spnRestaurante.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
            String selected = adapterView.getItemAtPosition(i).toString();
            restaurante.setRestaurante(selected);

            if(selected.equals("McDonalds")){
               //seta o adapter dos pratos para o spinner dos pratos
             } if(selected.equals("KFC")){
               //seta o adapter dos pratos para o spinner dos pratos
             }
        }
