Question

我已经检查并仔细检查了Stack Overflow以获得答案，我真的找不到答案。我正在使用离子框架构建一个应用程序，虽然我之前从未遇到过此问题，但由于某种原因，启动画面无法正常工作。我只是在初始视图加载之前得到一个完全白色的屏幕，然后是延迟。以下是我到目前为止所采取的步骤。

我通过添加splash.png和icon.png图像并使用“离子资源”来生成离子资源。终端中的命令（这很好，生成资产，图标确实有效）

通常这足以让它根据默认的离子框架设置显示启动画面，但没有运气。

我的配置xml文件看起来像这样

图像的所有路径都是正确的，我已经双重检查过了。我在构建期间没有出现任何错误，在我模拟时没有。我无法得到任何东西。白色屏幕确实显示3秒钟，因此我非常确定该应用程序找到相关的启动图像的问题。

Answer 1

转至：/usr/local/lib/node_modules/ionic/node_modules/ionic-app-lib/lib/resources.js
将 cacheImages 属性更改为 false
删除android平台
重新添加android平台
重新生成资源

在config.xml中确保代码配置如下：

<icon src="resources/android/icon/drawable-ldpi-icon.png" density="ldpi"/>
<splash src="resources/android/splash/drawable-port-xxxhdpi-screen.png" density="port-xxxhdpi"/>
<preference name="SplashScreen" value="screen"/>

Answer 2

您需要更改<platform>部分，使文件名为screen.png，如下所示。你的screen.png路径不正确每当你使用SplashScreen的任何名称而不是splash时，你需要更新配置：https://cordova.apache.org/docs/en/3.1.0/cordova/splashscreen/splashscreen.html#android

<platform name="android">

  <splash src="platform-resources/android/res/drawable-ldpi/screen.png" density="ldpi" />

  <splash src="platform-resources/android/res/drawable-mdpi/screen.png" density="mdpi" />

  <splash src="platform-resources/android/res/drawable-hdpi/screen.png" density="hdpi" />

  <splash src="platform-resources/android/res/drawable-xhdpi/screen.png" density="xhdpi" />

  <splash src="platform-resources/android/res/drawable-xxhdpi/screen.png" density="xxhdpi" />
</platform>
