private TextView t1;    private TextView t2;    private Button send;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_login);        t1= (TextView) findViewById(R.id.t1);        t2= (TextView) findViewById(R.id.t2);        send= (Button) findViewById(R.id.send);        send.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                EventBus.getDefault().register(LoginActivity.this);            }        });    }    @Subscribe(sticky = true)    public void onEventMainThread(FirstEvent event) {        String name = event.getName();        String password = event.getPassword();        t1.setText(name);        t2.setText(password);    }    @Override    protected void onDestroy() {        super.onDestroy();        EventBus.getDefault().unregister(this);    }
