再补一点自己调查的小知识：

firefly的rk3288android5.1系统里面，发现隐藏了状态栏后，在屏幕的下边缘上划，就会又调出状态栏：

贴上源码：

					
         private void removeBar(boolean needToast){					
             Log.d("LOUHN_DEBUG","in removeBar");					
             if (mBarIsAdd){					
                         Log.d(TAG,"remove Bar");					
					
                     //$_rockchip_$_modify_$_huangjc begin,add show/hide TitleBar          interface  for statusbar					
                     if(mContext.getResources().getConfiguration().enableMultiWindow()){					
                         try {					
                             mWindowManagerService.changeTitleBar(false);					
                         } catch (RemoteException e) {					
                             Log.w(TAG, "Error changeTitleBar transition: " + e);					
                         }					
                         }					
                     //$_rockchip_$_modify_$_end					
                         if (mNavigationBarView != null){					
                                 mWindowManager.removeView(mNavigationBarView);					
                        }					
                        if (!mContext.getResources().                                      getConfiguration().                     enableMultiWindow()&&mStatusBarWindow != null)					
                           mStatusBarWindow.setVisibility(View.GONE);					
                      if(signalCluster_win!=null)					
                           signalCluster_win=null;					
                       if (mNavigationBarView != null)					
                           mNavigationBarView = null;					
					
                       if(mNotificationLite != null){					
                         mNotificationLite.closeCenter();					
                       }					
                         mBarIsAdd = false;		//注意这个变量			
                         if(!isMultiChange)					
                         Toast.makeText(mContext, mContext.getResources().                 getString(R.       string.hidebar_msg)					
 , 1000).show();					
					
                 }					
         }					

在 removeBar()这个方法里面变量mBarIsAdd = false;

上划操作会调用addBarinside()方法，由于mBarIsAdd被设为了false，所以这里就直接执行了addBar的方法，被隐藏的状态栏又出现了如果不想上划出现状态栏，只要把removeBar()方法里面，把mBarIsAdd=false删除就可以了

         private void addBarInside(){				
                 Log.d("LOUHN_DEBUG","in addBarInside()");				
                 if (!mBarIsAdd){		  //注意这个判断		
                         Log.d(TAG,"add Bar");				
                     Log.d("LOUHN_DEBUG","in addBarInside()222");				
 				
           try {				
             boolean showNav = mWindowManagerService.hasNavigationBar();				
             if (DEBUG) Log.v(TAG, "hasNavigationBar=" + showNav);				
             if (showNav) {				
                 //haungjc:win bar				
                 if(mContext.getResources().getConfiguration().enableMultiWindow()){				
                     //$_rockchip_$_modify_$_huangjc begin,add show/hide TitleBar interfac for statusbar				
                     try {				
                         mWindowManagerService.changeTitleBar(true);				
                     } catch (RemoteException e) {				
                         Log.w(TAG, "Error changeTitleBar transition: " + e);				
                     }				
                     //$_rockchip_$_modify_$_end				
                     mNavigationBarView =				
                     (NavigationBarView) View.inflate(mContext, R.layout.                  navigation_bar_win, null);				
               }else{				
                 mNavigationBarView =				
                     (NavigationBarView) View.inflate(mContext, R.layout.navigation_bar,   null);				
               }				
                 mNavigationBarView.setDisabledFlags(mDisabled);				

划后调用addBarInside()方法
