cordova启动页面和图标的设置

原文地址

config.xml配置

在cordova5.0版本以后，需要安装cordova-plugin-splashscreen插件以后才能修改和设置App的启动页面。

安装splashscreen插件：

cordova plugin add cordova-plugin-splashscreen
或
cordova plugin add https://github.com/apache/cordova-plugin-splashscreen.git

基本配置

然后在你的config.xml文件中，添加以下代码

<platform name="android">  
    <icon density="ldpi" class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="res/icon/android/icon-36-ldpi.png" />

其他配置

• 自动隐藏启动页面AutoHideSplashScreen（默认为：true）

    <preference name="AutoHideSplashScreen" value="true" />

• 显示启动页面的时间长度SplashScreenDelay(默认为：3000)

    <preference name="SplashScreenDelay" value="3000" />

  若想禁用启动页面，可设置为：<preference name="SplashScreenDelay" value="0"/>

  如果是iOS平台上想禁止启动页面，还需要添加<preference name="FadeSplashScreenDuration" value="0"/>

• 启动页面淡入淡出的效果

  是否显示淡入淡出效果FadeSplashScreen(默认为：true)

    <preference name="FadeSplashScreen" value="false"/>

  淡入淡出效果的执行时间长度FadeSplashScreenDuration(默认为：500)

    <preference name="FadeSplashScreenDuration" value="750"/>

  注意：FadeSplashScreenDuration时间是包含在SplashScreenDelay的时间里的。

• 启动页面是否允许旋转（默认为：true）

    <preference name="ShowSplashScreenSpinner" value="false"/>

• 插件还可以通过js代码调用，提供有以下两个方法：

    navigator.splashscreen.hide();//隐藏启动页面
  
    navigator.splashscreen.show();//显示启动页面

• 在Android平台下的特殊设置

    <preference name="SplashMaintainAspectRatio" value="true|false" />
    <preference name="SplashShowOnlyFirstTime" value="true|false" />

  SplashMaintainAspectRatio：选填项，默认为false。当设置为true时，则不会拉伸图片来填充屏幕，会以图片原始比例显示图片。

  SplashShowOnlyFirstTime：选填项，默认为true。当设置为false时，APP通过navigator.app.exitApp()代码退出app后，在下次打开APP时，还会显示启动页面。若为true时，就不会出现。

图标文件夹内容

根据上面的配置信息，你需要准备好你自己的app图标和启动画面png文件：

存放路径不是以www文件夹为依据，而是以当前项目文件夹为依据

projectRoot
    hooks
    platforms
    plugins
    www
        css
        img
        js
    res
        screen
            android
            ios
        icon
