==========================================================
最新版Cordova CLI已经支持在config.xml中配置<splash> 和 <icon>,CB-2606, CB-3571 Add support for <icon>, <splash>。设置如下:
<platform name="android">
    <icon src="res/android/icon-36-ldpi.png" density="ldpi" />
    <splash src="res/android/screen-xhdpi-portrait.png" density="port-xhdpi"/>
</platform>

具体可以参考官方文档:Icons and Splash Screens

如果你本地安装了ImageMagick,CLI还会自动调用ImageMagick来做成不同尺寸的图像。
需要注意的是:
(1)图像的路径是相对于工程根目录不是根据www
(2)不要和PhoneGap CLI的设置混淆
==========================================================


(1)创建以下图像

以Android为例:

icon图像:
  • www/res/icon/android/icon-36-ldpi.png - 36px x 36px
  • www/res/icon/android/icon-48-mdpi.png - 48px x 48px
  • www/res/icon/android/icon-72-hdpi.png - 72px x 72px
  • www/res/icon/android/icon-96-xhdpi.png - 96px x 96px

splashscreen图像:
  • www/res/screen/android/screen-ldpi-landscape.png - 320px x 200px
  • www/res/screen/android/screen-mdpi-landscape.png - 480px x 320px
  • www/res/screen/android/screen-hdpi-landscape.png - 800px x 480px
  • www/res/screen/android/screen-xhdpi-landscape.png - 1280px x 720px
  • www/res/screen/android/screen-ldpi-portrait.png - 200px x 320px
  • www/res/screen/android/screen-mdpi-portrait.png - 320px x 480px
  • www/res/screen/android/screen-hdpi-portrait.png - 480px x 800px
  • www/res/screen/android/screen-xhdpi-portrait.png - 720px x 1280px

(2)给工程添加splashscreen插件
引用
> cordova plugin add org.apache.cordova.splashscreen


(3)配置config.xml
<preference name="SplashScreen" value="splash" /> <!-- 不带后缀png的文件名,默认是screen-->
<preference name="SplashScreenDelay" value="10000" /> <!-- Splash显示时间,默认是3000ms-->

<feature name="SplashScreen">
  <param name="android-package" value="org.apache.cordova.splashscreen.SplashScreen" />
</feature>


相比于在config.xml中设置延迟时间,更应该在设备初始化完成后隐藏Splash画面(index.html)
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
  navigator.splashscreen.hide();
}


(4)Copy文件
phonegap是可以在config.xml中配置icon和splash的,但是cordova不支持,需要在cordova build之后Copy文件,也可以通过创建hook来实现。
***phonegap的配置也局限于remote build的时候Phonegap Build起作用,local build也不起作用,需手动处理。参考这里

icon.png:
把www/res/icon/android下的文件Copy到相应的platforms/android/res/drawable*/下。

splash.png:
把www/res/screen/android下的文件Copy到相应的platforms/android/res/drawable*/下。

完成以后启动“cordova emulate android”即可。
