一种临时解决方案，在切换动画加载完毕后，再去构造 WebView，这样从用户角度上看，就不会有路由切换动画的卡顿了。class WebViewPage extends StatefulWidget {undefined

final String uri;

WebViewPage({undefined

@required this.uri,

}) : assert(uri != null);

@override

_WebViewPageState createState() = _WebViewPageState();

}

class _WebViewPageState extends State {undefined

WebViewController _controller;

bool _animationCompleted = false;

@override

Widget build(BuildContext context) {undefined

// 主要是下面的代码

var route = ModalRoute.of(context);

if (route != null !_animationCompleted) {undefined

void handler(status) {undefined

if (status == AnimationStatus.completed) {undefined

route.animation.removeStatusListener(handler);

setState(() {undefined

_animationCompleted = true;

});

}

}

route.animation.addStatusListener(handler);

}

return Scaffold(

title: widget.title,

backgroundColor: Colors.white,

body: _animationCompleted

? WebView(

initialUrl: 'about:blank',

onWebViewCreated: (WebViewController webViewController) {undefined

_controller = webViewController;

_loadHtmlFromAssets();

},

)

: Container(),

);

}

_loadHtmlFromAssets() async {undefined

var uri = Uri.dataFromString(

await rootBundle.loadString(widget.uri),

mimeType: 'text/html',

encoding: Encoding.getByName('utf-8'),

).toString();

_controller.loadUrl(uri);

}

}

美国高校高水平游泳队常用蛙泳技术训练方法是什么？

国内高校游泳教练员在蛙泳技术训练上,要多运用分解技术练习,发散思维,设计更多不同的练习手段,让训练内容更丰富,调动运动员的积极性,使其更好地了解掌握技术动作,提高训练实效性。针对国外的各种水下辅助工具,可以在了解其特性的基础上,加以改进借鉴,得出属于我国自有研发的游泳辅助训练器材,进而推动国内高校游泳市场的需求,也为国内高校游泳队提供一定先进性、科学性的训练保障。

一，美国高校高水平游泳队常用蛙泳技术训练方法

(1)三次蛙泳腿一次蛙泳手(3kick-1 pull breast),低头,两臂夹紧并拢伸直,蹬壁出发,要求蹬三次蛙泳腿划一次蛙泳手的节奏完成动作,重点要求运动员上身保持流线型,两臂与髋部,不要上下晃动,保持稳定。训练中分解练习的蹬腿次数可以针对试用与不同的运动员,能力越高的队员可以加大蹬腿次数与划臂的配合,反之,相对减少。

(2)蛙泳划手蝶泳打腿(br w/dolphin kick),要求运动员按照一次蛙泳手,一次蝶泳腿的节奏进行练习,其目的是控制身体流线型,保持游进的稳定性。训练中也可增加难度,如把头抬起,一直保持在水面;蛙泳腿、蝶泳腿交替等训练手段,后者可加强纠正蛙泳收腿动作。值得注意的是,通过对主教练团队的访谈得知,国内蛙泳训练常见的一次蛙手两次蝶腿的技术动作,在国外比较少用,因从蛙泳技术动作的结构而言,如采用两次腿一次手的技术练习,会间接破坏身体游进的流线型,从而达不到此练习方法的效果。

(3)蛙泳划手自由泳打腿(br w/flutter kick),要求运动员按照一次蛙泳划手,六次自由泳打腿的节奏进行练习,其目的是为了控制运动员上身及手臂划动后保持身体在水中的流线型。其中要注意自由泳打腿的次数取决于划幅与划频,越快越好,持续不间断,如能完成每次划手动作配合6～8次的打腿,效果会更好。

二， 蛙泳技术动作的水下辅助工具训练方法

阻力袜是类似一个网袋状套在运动员双脚上,其分有大、中、小等型号,以此来增加双脚的动作阻力,此辅助工具适用于蛙泳腿部技术动作的练习,一般采用小号,在加大阻力的基础上,让运动员提高腿部的收蹬频率,快速的完成技术动作。对国内的各高校教练员访谈中得知,现下国内各高校游泳队在游泳辅助工具中,针对上肢练习的种类较多,像陆上有各种拉力器材,水中也有不同类型的划水掌运用在不同的技术练习中,但对腿部的水中辅助练习方法还比较缺乏,为此,笔者认为,这方面值得我们学习与借鉴。
