我在申请时使用V4图书馆的 ViewPager
在主屏幕中,我有一个查看器Pager, 最大5个碎片, 所有碎片都属于一个类 文章Pager
现在在主屏幕上,有分类列表, 现在传呼机的内容是基于此选择,
我面临的问题是,我使用了存储碎片的 < code> FragmentPagerAdapter 。 如果碎片已经存在, 它会返回旧的碎片, 而不重造它。 事情运行得完美, 但是问题代码@ 方向改变的时间 。
例如
如果每个碎片中通常有 5 视图, 则给定位置, 但也有一些含有 2-3 视图 。 如果我在 第 页中“ 强” 更改方向 < 强” / “强”, 则“ 强” 。
所以,到现在,第5页的每一个类别中,我都会得到包含3种观点的观点,这不是我想要的。
在我的申请表中,每一类别都包含页数
<强> 是否有办法可以让我在点击分类时销毁和重新生成碎片? 或任何其他围绕工作。
谢谢
OK 多亏了开放源码 我找到了我的解决方案 http://code.google.com/p/openintents/source/browse/trunk/compatibility/AndroidSupplyV2/src/android/support/v2/app/FragmentPagerAdapter.java?r=3488" rel="noreferr"\\code >FraggermentPaggerAdapter 我推翻了方法 instantiateTroup 并得到了解答。
这很容易通过Fraferment StatePagerAdapter 来实现。 它总是重新创建它, 但我不想在每页的100秒里保存, 因为只有几页。
所以,如果我理解正确的话, 你的问题是,在旋转后, 一组错误的碎片在您 ViewPager 中?
您为什么不检查您活动的Resume () 或 Start () 中当前选中的标签, 并创建/ 指定一个新的 PagerAdapter 来为您使用正确的碎片显示 ViewPager?
