Cannot resolve symbol 'window' error

Question

When I add "this.requestWindowFeature(Window.FEATURE_NO_TITLE);" to my activity, IDE redden 'Window' word and on tooltip it warns me by "cannot resolve symbol 'window'"

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_splash_screen);

Any help would be appreciated.

Press and hold ctrl key ( command on MAC ) and click on 'window' text . A orange bulb will show up on the left panel , click on it , it will ask you to import necessary module .
