当按下按钮时更改XML布局

Question

我试图在按下按钮时更改滚动视图内部的线性布局的xml布局/内容。当按下按钮或使用setVisibility时，我不想调用新的Activity。

到目前为止，屏幕的10％被预留为一个导航栏外壳2个按钮。下面是一个内部呈线性布局的滚动视图，其内部将是内容。当按下“下一个”按钮时，我希望在线性布局内更改内容。 这是一个参考应用程序，旨在保存50页以上的信息。

Answer 1

您可以使用FragmentPager

Answer 2

你不说为什么你不希望使用setVisivility()，但我的第一个建议是使用基于可见或不可见一个FrameLayout并设置不同的看法按钮按下。另一个想法是使用ViewFlipper。
