Dynamically editing a variable in android

1
Hello, I have an Activity that has some TextView fields and I'm putting down some EditText so that I want to change these fields. I insert the data and click on the button and it automatically goes there and changes these TextViews to me I can not find something like this on the net ...

So I did something but it was not right:

Activity Code

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

I do not know why I could not put the whole code so follow an image of the Activity (just below the Change Profile is the EditText that I want to set them the same with TextView)

Nowfollowsmycodeattempt

publicclassProfileActivityextendsAppCompatActivity{

privateDatabaseReferencefirebase;privateTextViewNome;privateTextViewEmail;privateTextViewtelefone;privateTextViewNumeroCartão;privateTextViewCodCard;privateEditTextEditName;privateEditTextEditEmail;privateEditTextEditTelefone;privateEditTextEditCartao;privateEditTextEditCodCartao;privateButtonAlterar;publicEditablenome="Victor Roja Tavoni";
public Editable email = "[email protected]";
public Editable Telefone = "+5519997749701";
public Editable Cartão = "0000000000000000";
public Editable codCard = "123";



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_perfil);

    Nome = (TextView) findViewById(R.id.textViewNome);
    Email = (TextView) findViewById(R.id.textViewEmail);
    telefone = (TextView) findViewById(R.id.TextViewTelefone);
    NumeroCartão = (TextView) findViewById(R.id.textViewNumeroCartao);
    CodCard = (TextView) findViewById(R.id.CodCartaoPerfil);
    EditName = (EditText) findViewById(R.id.editTextNomePerfil);
    EditEmail = (EditText) findViewById(R.id.editTextMailPerfil);
    EditTelefone = (EditText) findViewById(R.id.editTextTelefone);
    EditCartao = (EditText) findViewById(R.id.editTextCartãoPerfil);
    EditCodCartao = (EditText) findViewById(R.id.editTextCodCartaoPerfil);
    Alterar = (Button) findViewById(R.id.buttonAlterarPerfil);


    nome = "Victor Roja Tavoni";
    email = "[email protected]";
    Telefone = "+5519997749701";
    Cartão = "0000000000000000";
    codCard = "123";



    Nome.setText("Nome: " + nome);
    Email.setText("Email: " + email);
    telefone.setText("Telefone: " + Telefone);
    NumeroCartão.setText("Numero Cartão: " + Cartão);
    CodCard.setText("Cod. Cartão: "+codCard);

    Alterar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            nome = EditName.getText();
            email = EditEmail.getText();
            Telefone = EditTelefone.getText();
            Cartão = EditCartao.getText();
            CodCard = EditCodCartao.getText();
        }
    });





}

}
