Change Text Hint To Message String?

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);[code]....

My app includes a search bar. In the first activity the user types into it what they are looking for. What I am currently trying to do is try to change the text hint to the message string. This string contains what the user typed in the previous search bar.
