【快应用】快应用中开屏广告模拟

 【关键词】

开屏、原生广告、stack

 

【问题背景】

快应用中目前暂时不支持开屏广告,开发者如想在应用启动时展示广告,可以在快应用中用原生广告来模拟替代,从而来实现开屏广告的效果。

 

【问题分析】

实现上是比较简单的,首先需要将首页替换成一个只有原生广告展示的ux页面,然后在展示几秒后,通过router接口跳转到快应用的实际首页。

同时在模拟的开屏广告页上还需要加个关闭广告的按钮,可以点击后提前关闭广告跳转到后续页面。

 

【解决方案】

布局方面实现:

1、  由于原生广告返回的可能是图片或者视频,需要使用stack组件将它们堆叠在一起实现,后续可以根据原生广告请求返回的值来决定使用image还是video组件。

    <stack class="stackstyle" onclick="reportNativeClick()">

      <image if="native.isShowImg" class="img" src="{{native.adImgSrc}}"></image>

      <video id="video" if="native.isShowVideo" src="{{native.adVideoSrc}}" autoplay="true" onclick="reportNativeClick()" class="video"></video>

    </stack>

2、  关闭按钮实现,通过position属性将关闭按钮固定在右上角。

<text class="closebtn" onclick="closeAd">关闭{{value}}</text>

    .closebtn {

      width: 80px;

      height: 60px;

      border-radius: 30px;

      font-size: 25px;

      text-align: center;

      border: 1px solid #d1cdcd;

      right: 10;

      top: 10;

      position: absolute;

    }

主要逻辑代码实现:

1、  开屏广告的请求与展示(其实就是原生广告的请求与展示)

2、  通过定时器来实现一个倒计时效果,在广告展示几秒后自动跳转下一页面。

3、  关闭按钮点击,关闭广告展示和立即跳转下一页面。

        onShow(options) {

            '// Do something .'

            this.showNativeAd()

            this.cutdown()

            setTimeout(() => {

                router.replace({

                    uri: '/Hello',

                })

            }, 4000);

        },

        cutdown() {

            var timer = setInterval(() => {

                this.value--

            }, 1000);

            if (this.value === 0) {

                clearInterval(timer);

            }

            console.log(222);

        },
