   super.onSaveInstanceState(outState);

  String tempDate= (((EditText)findViewById(R.id.editText1)).getText()).toString();

  outState.putString("data_key",tempDate);

}

@Override

protected void OnCreate(Bundle savedInstanceState){

    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.main);

    if(savedInstanceState!=null){

           String tempDate=savedInstanceState.getString("data_key");

          ((EditText)findViewById(R.id.editText1)).setText(tempDate);

           Button button1=(Button) findViewById(R.id.button1);
         button1.setOnClickListener(new OnClickListener(){


     @Override
