Help, I need to insert a value that comes from a putextra, adroid studio and mysql

// THIS IS MY ACTIVITY FROM INSERTING USER

The value is an extra put, loguser, it shows me the value on the screen but it does not register it in the database.

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_usuario);

    logusuario=(EditText) findViewById(R.id.etingresadopor);
    Intent intmostrar= getIntent();
    mostrardelogin=intmostrar.getExtras().getString("UsuarioMostrar");
    logusuario.setText(mostrardelogin);


    et1 = (EditText) findViewById(R.id.codeAddUser);
    et2 = (EditText) findViewById(R.id.etusaurioAddUser);
    et3 = (EditText) findViewById(R.id.etpassAddUser);
    btnAddUser = (Button) findViewById(R.id.btnAddUser);
    btnSalir = (Button) findViewById(R.id.btnExit);
    btnAddUser.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            submitForm();
            et1.requestFocus();
            Limpiar();
        }
    });

}
