Question

I have a user "update" screen that would update data in my database .. How to do this update in my bank in Android Studio ? My code is like this :

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


        txtname1 = (EditText) findViewById(R.id.txtname1);
        txtnick1 = (EditText) findViewById(R.id.txtnick1);
        edittextpassword = (EditText) findViewById(R.id.edittextpassword);
        edittextnumcel = (EditText) findViewById(R.id.edittextnumcel);
        edittextID = (EditText) findViewById(R.id.tx_id);
        Tv_mail = (EditText) findViewById(R.id.tvmail);
        Attcadastro = (Button) findViewById(R.id.attcad);



            Attcadastro.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    nome = txtnick1.getText().toString();
                    nickname = txtnick1.getText().toString();
                    password = edittextpassword.getText().toString();
                    numcel = edittextnumcel.getText().toString();
                    email = Tv_mail.getText().toString();
                    id = edittextID.getText().toString();

                   new PatchClass().execute();


                }
