java - How to call requestWindowFeature inside Fragment -

-

मैं कॉल करना चाहता हूं: 

  requestWindowFeature (Window.FEATURE_INDETERMINATE_PROGRESS);

लेकिन नीचे दिए गए कोड काम नहीं कर रहे हैं: 

  @ ओवरराइड सार्वजनिक देखें क्रिएटिव्यू (लेआउटइफलटर इन्फ्लाटर, व्यू ग्रुप कंटेनर, बंडल सहेजे गए इन्स्टेंसस्टेट) {requestWindowFeature (विंडो.FEATURE_INDETERMINATE_PROGRESS ); रूटव्यू देखें = inflater.inflate (R.layout.fragment_login, कंटेनर, गलत); वापसी रूट दृश्य; } // end onCreateView

कोई व्यक्ति हाथ दे सकता है, pls धन्यवाद

यह फ्रेगमेंट 

  getActivity () requestWindowFeature (Window.FEATURE_INDETERMINATE_PROGRESS)।
