标签: android android-tabs layout-inflater android-tablayout

我在为标签布局中的标签设置自定义视图时遇到错误。每个选项卡在第一次运行时运行正常,但是当我在选项卡之间滑动时,会出现运行时错误。我只是第一次尝试标签布局,有人可以帮我这个吗?

答案很简单:根本不使用xml片段。它支持不好,有很多限制,就像你遇到的那样。
问题是两个相同的xml片段(没有解决方法)不能一起存在,因为它们共享相同的片段id。当历史片段由于页面更改过程而尝试重新创建它时,崩溃发生,但之前的片段仍然没有被垃圾收集。

当然,在你的情况下你仍然可以在setOffscreenPageLimitViewPager到2(所有视图都将保留在内存中),但你应该只删除你的xml片段并在必要时以编程方式附加它。 / p>
