Refresh Image

Question

I have a question, because I’m setting the picture from Spinner’s position. Then, when you open Activity, the Oncreate method reads the position of the spinner and loads the image according to its type.

However, I would like to know how to set the position of Spinner whenever the user clicks on the spinner and change position.

teste = arrayLitros.get(spnProdutos.getSelectedItemPosition()).toString();
    teste2 = arrayUnidadeL.get(spnProdutos.getSelectedItemPosition()).toString();


    if(teste.equals("20") && teste2.equals("L")){
        imgProduto.setImageResource(R.drawable.img1);
    }
    else if(teste.equals("10") && teste2.equals("L")){
        imgProduto.setImageResource(R.drawable.img2);
    }
    else if(teste.equals("2") && teste2.equals("L")){
        imgProduto.setImageResource(R.drawable.img3);
    }
    else if(teste.equals("3") && teste2.equals("M")){
        imgProduto.setImageResource(R.drawable.img4);
    }
