Android4.0设置界面修改总结(三)


Android4.0设置界面修改总结大概介绍了一下设置改tab风格,其实原理很简单,理解两个主要的函数即可:

①.invalidateHeaders(),调用此函数将重新调用onBuildHeader()来重新读取xml文件中的header,重新刷新HeaderAdapter中的数据,因此刷新了ListView的内容,从而更新了界面。

②.onBuildHeaders()中调用loadHeadersFromResource(resId, headers); 即可重新加载HeaderAdapter的数据。


但是上次有一个问题,不能横竖屏切换,因为有一些bug未解决,所以我在onCreate中加入了:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);这一句,

另外代码结构稍微调整了一下,再和大家分享一下。

主要修改有以下两点:

①.可以横竖屏切换,主要是在HeaderAdapter中加入了一个函数:flushViewCache()。允许横竖屏切换时重新刷新数据。

②.将每个tab对应的xml布局当成每个tab的tag传递给onBuildHeaders,重新刷新缓存的HeaderAdapter。


好了,废话不多说了,直接上源码。可以搜索标签 20140601,即可找到我所有的修改。
