Question

有人可以帮助我吗？我知道这里有一些问题。为什么我必须在页眉末尾和页面底部链接bootstrap.min.js。我曾尝试过一次使用一个，但它不起作用。接下来的事情是，当我加载页面和单击控制器时，我希望旋转木马启动;不只是当我点击控制器。

Answer 1

我刚刚设置了一个Fiddle，其中包含您示例的轮播，jQuery版本2.1.3，bootstrap.js和bootstrap.css作为外部资源以及您的脚本以转发轮播

$('#myCarousel').carousel({
  interval: 3000,
  cycle: true
});

它正在工作 - 它在页面加载和控制器工作时启动。它不适合你可能是在jQuery之前加载bootstrap的问题 - 在引导之前必须包含jQuery。要检查是否是这种情况，请查看是否有任何错误/控制台消息，如“错误：Bootstrap的JavaScript需要jQuery”。此外，您还包括2个不同的jQuery版本 - 1.11.1和2.1.3。如果没有必要，例如对于一些依赖于旧版jQuery版本的插件，请尝试加载最新的版本此外，您将在关闭正文和html标记之间放置脚本标记，这些标记可以正常工作但无效 - 有关详细信息，请参阅link, script tags between </body> and </html>。作为使用不同jQuery版本的参考，如果真的有必要，可以查看http://api.jquery.com/jquery.noconflict/

Answer 2

您可以通过带有data-interval标记的HTML来完成此操作。将其插入<div id="myCarousel" class="carousel slide">，如下所示：

<div id="myCarousel" class="carousel slide" data-interval="3000">

可以将3000的值调整为较高的数字以降低速度，将较低的数字调整为可以提高速度。

Answer 3

在包含的轮播div中添加自定义属性@Override protected void onRestoreInstanceState(Bundle savedInstanceState) { if(savedInstanceState != null){ mTextBox.setText(savedInstanceState.getString("name")); } }。您可以选择添加data-ride="carousel"来更改滑块更改持续时间（以毫秒为单位）。
