如何在android中全屏显示特定视图

Question

我正在使用视频播放器应用程序，我使用let showMerchantInfoUrl=NSURL(string:"http://www.someurlhere.com") let showMerchantInfoRequest=NSMutableURLRequest(URL:showMerchantInfoUrl!) showMerchantInfoRequest.HTTPMethod="POST" let showMerchantInfoString="token=\(KeychainWrapper.stringForKey("tokenValue")!)"; showMerchantInfoRequest.HTTPBody=showMerchantInfoString.dataUsingEncoding(NSUTF8StringEncoding) //send the request let task=NSURLSession.sharedSession().dataTaskWithRequest(showMerchantInfoRequest) { data, response, error in if error != nil { print("error=\(error)") return } do { let json=try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary if let parseJSON=json { let codeValue = parseJSON["code"] as? Int let msgValue = parseJSON["msg"] as? String if codeValue! == 1 { print(json) dispatch_async(dispatch_get_main_queue(), { if let retDictionary = parseJSON["ret"]!["info"] as? NSDictionary { self.shopName.text = retDictionary.valueForKey("mer_name") as? String if retDictionary.valueForKey("mer_name") as? String != nil { KeychainWrapper.setString(self.shopName.text!, forKey: "shopName") self.totalCouponsTaken.text = String(self.nullToZero(retDictionary.valueForKey("visits"))!) + "人" self.unusedCoupons.text = String(self.nullToZero(retDictionary.valueForKey("coupon_not_used_yet"))!) + "人" self.totalCouponsTaken.text = String(self.nullToZero(retDictionary.valueForKey("coupon_taken_total_numbers"))!) + "人" self.merchantRatingCV.rating = Double(self.nullToZero(retDictionary.valueForKey("star"))! as! NSNumber) KeychainWrapper.setString(String(self.nullToZero(retDictionary.valueForKey("star"))!), forKey: "shopRating") self.merchantRatingCV.text = String(self.nullToZero(retDictionary.valueForKey("star"))!) } } if let retAlbumArray = parseJSON["ret"]!["album"] as? NSArray { print("REEET :\(retAlbumArray)") self.albumImagePathArray = retAlbumArray.flatMap({ element in (element["mer_thumb"] as? String)! }) self.albumImageID = retAlbumArray.flatMap({ element in (element["album_id"] as? String)! }) self.coverableArray = retAlbumArray.flatMap({ element in (element["coverable"] as? String)! }) for i in 0 ..< self.albumImagePathArray.count { let request: NSURLRequest = NSURLRequest(URL: NSURL(string: self.albumImagePathArray[i])!) let mainQueue = NSOperationQueue.mainQueue() NSURLConnection.sendAsynchronousRequest(request, queue: mainQueue, completionHandler: { (response, data, error) -> Void in print("asdfasdfasdfasfdasfasdf") if error == nil { let image = UIImage(data: data!) self.albumImages.append(image!) } else { print(error) } }) } if self.albumImages.count >= self.maximumImagesAllowed { disableAdditionOfImages=true } else { self.albumImages.append(UIImage(named:"Plus.png")!) } if self.disableAdditionOfAlbumImages == false && self.albumImages.count > 1 { let bannerPhoto=self.albumImages[0] self.bannerImage.image = bannerPhoto } UIView.performWithoutAnimation { self.albumCollectionView?.reloadData() self.activeIndicator.stopAnimating() } if self.albumImagePathArray==[] { self.activeIndicator.stopAnimating() } } else { self.activeIndicator.stopAnimating() } if codeValue!==1 { print(json) } else { self.showSimpleAlert(msgValue!, message: nil, segueToLogin: false) } }) } else { self.showSimpleAlert(msgValue!, message: nil, segueToLogin: true) } } } catch let err { print(err) } } task.resume(); 和MediaPlayer来控制视频播放。一切都还可以，但我的问题是我必须实现全屏功能，用户点击全屏按钮全屏显示带控制器的播放器（如：播放，暂停，搜索栏e.t.c）。我希望和Youtube的全屏功能一样。我怎样才能做到这一点 ？

布局文件 - ＆gt;

SurfaceView

看起来像这样 - ＆gt;

此外，活动 - ＆gt;

我正在使用this教程来实现视频播放器。我只需要实现全屏功能。

请不要告诉我任何第三方图书馆
