javascript - 启动应用程序时出现启动画面

标签 javascript android cordova mobile splash-screen

我目前正在使用 apache cordova 创建一个应用程序。当我的应用程序启动时，我需要让启动画面显示出来。我试图从互联网上搜索如何执行此操作的信息，但没有任何好的结果。我想补充一点，我使用的是 JS、HTML 和 CSS (+XML)。

目前；我已经安装了扩展程序 - 启动画面，我在 config.xml 中的代码如下所示；

<?xml version="1.0" encoding="utf-8"?>

那么，我应该如何解决这个问题？如何让启动画面在应用程序启动后显示几秒钟。

最佳答案

从我的工作项目中检查我的 ios 和 Android 设置。 我阅读了一个项目，该项目有助于在我的应用程序未完成加载时阻止启动画面消失，下面的设置允许启动画面保持打开状态，直到设备准备好然后清除它。效果很好。

<platform name="android">
    <allow-intent href="market:*" />
    <preference name="SplashScreen" value="screen" />
    <preference name="SplashScreenDelay" value="10000" />
    <preference name="SplashShowOnlyFirstTime" value="false" />
    <preference name="FadeSplashScreen" value="false" />
    <preference name="AutoHideSplashScreen" value="false" />
    <preference name="ShowSplashScreenSpinner" value="true" />
    <!-- 10000 to keep open whilst heating page is loaded into DOM -->
    <preference name="SplashMaintainAspectRatio" value="true" />
  </platform>
  <platform name="ios">
    <preference name="FadeSplashScreen" value="false" />
    <preference name="SplashScreen" value="screen" />
    <preference name="AutoHideSplashScreen" value="false" />
  </platform>

同样在 Index.js 中，您需要添加一些代码:-

在您的设备就绪功能中:

    setTimeout(function () {
        navigator.splashscreen.hide();
    }, 50);

有很多混合文档，但我可以确认上述设置适用于我的项目。
