導航抽屜中的刷新標題

Question

雖然我一直在四處尋找，但找不到正確的答案。 在我的導航抽屜標題中，我向用戶提供了他的圖像和名稱，但是我也允許用戶從應用程序更改他/她的名字和圖像。 這些更改存儲在會話管理器中。 現在我想在我的導航抽屜標題中反映這些更改。 一切工作正常，因爲當我關閉應用程序並再次運行它顯示更改。 因此，現在我需要的是一種刷新導航抽屜標題的方法。

從配置文件片段中的庫中選擇圖像。

private void onSelectFromGalleryResult(Intent data) { 

     String selectedImagePath = getPathFromCameraData(data, getActivity()); 

     Bitmap bm; 
     BitmapFactory.Options options = new BitmapFactory.Options(); 
     options.inJustDecodeBounds = true; 
     BitmapFactory.decodeFile(selectedImagePath, options); 
     final int REQUIRED_SIZE = 200; 
     int scale = 1; 
     while (options.outWidth/scale/2 >= REQUIRED_SIZE 
       && options.outHeight/scale/2 >= REQUIRED_SIZE) 
      scale *= 2; 
     options.inSampleSize = scale; 
     options.inJustDecodeBounds = false; 
     bm = BitmapFactory.decodeFile(selectedImagePath, options); 
     bitmap = bm; 
     profilephoto = BitMapToString(bm); 

     session.setprofilepic(profilephoto);// make changes in session. 
      profilepic.setImageBitmap(bm); 

    }

雖然我張貼的答案這麼晚真是不好意思。 我解決了我的問題，只要打開抽屜就可以刷新標題，或者我們可以在調用onDrawerOpened時解決問題。

mDrawerToggle = new ActionBarDrawerToggle(Homepageactivity.this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) { 

     /** Called when a drawer has settled in a completely closed state. */ 
     public void onDrawerClosed(View view) { 
      super.onDrawerClosed(view); 
      getSupportActionBar().setTitle(mTitle); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 

     /** Called when a drawer has settled in a completely open state. */ 
     public void onDrawerOpened(View drawerView) { 
      super.onDrawerOpened(drawerView); 
      getSupportActionBar().setTitle(mDrawerTitle); 
      session = new SessionManager(getApplicationContext()); 
      user = session.getUserDetails(); 
      profilepic.setImageBitmap(StringToBitMap(user.get(SessionManager.KEY_PROFILEPIC))); 
      name.setText(user.get(SessionManager.KEY_NAME)); 
      lastsynced.setText(lastsynced()); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 
    };
