Get Value of a Edit Text field

Question

I am learning how to create UI elements. I have created a few EditText input fields. On the click of a Button I want to capture the content typed into that input field.

Answer 1

    Button kapatButon = (Button) findViewById(R.id.islemButonKapat);
    Button hesaplaButon = (Button) findViewById(R.id.islemButonHesapla);
    Button ayarlarButon = (Button) findViewById(R.id.islemButonAyarlar);

    final EditText ders1Vize = (EditText) findViewById(R.id.ders1Vize);
    final EditText ders1Final = (EditText) findViewById(R.id.ders1Final);
    final EditText ders1Ortalama = (EditText) findViewById(R.id.ders1Ortalama);

    //

    final EditText ders2Vize = (EditText) findViewById(R.id.ders2Vize);
