    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        

        button = (Button)findViewById(R.id.button1);

        text = (EditText)findViewById(R.id.editText1);

        lly = (LinearLayout)findViewById(R.id.main1);
