Android 在FrameLayout外部的textview中更改文本时，FrameLayout动画不起作用

我已将库中的FrameLayout用作库项。FrameLayout中有两个RelativeLayout，每个都包含一些TextView和一个ImageView。画廊外有一个叫做“翻转”的按钮。单击按钮“翻转”隐藏一个相对布局，并显示另一个具有翻转动画的布局。画廊外还有一个文本视图，我在其中更新了一些文本。当用户滚动Gallery以选择其他项目时，我会从Gallery的setOnItemSelected方法更新TextView

问题是，如果我不使用setOnItemSelected方法更新TextView，翻转动画将正常工作。但是，如果我更新了TextView，那么动画就不起作用了。甚至它也不会在FrameLayout内切换RelativeLayout

如果有人知道问题出在哪里，请帮助我

有人知道这个问题吗。请帮助。

在您的主布局中，为什么您将RelativeLayout04作为顶级线性布局的唯一子级？我认为你的布局的复杂性可能与这个问题有关，所以我在这里提供了一个更简单的选择，它使用android：布局权重，使图库填充页眉或页脚未使用的空间。让我知道这是否有帮助
