平板电脑UI无效

标签： java android android-layout android-fragments

我正在制作一个向用户展示热门电影网格的应用，当用户点击其中一个项目时，它会显示电影的详细信息。

该应用在手机上运行良好，但我的平板电脑用户界面实现无效

我没有遭遇任何崩溃因此，当我点击一部电影时，详细信息不会显示在平板电脑上。

以下是GitHub回购的链接 - https://github.com/Hackertronix/Project-Motion/tree/Stage_2?files=1

以下是与平板电脑用户界面相关的文件

我认为你应该在布局中为移动设备和平板电脑编写相同的xml文件 layout-sw600dp文件夹。系统将按文件夹名称选择。如果您将在手机中打开，它会从布局文件夹中选择布局，如果您将在平板电脑中打开，则会选择 layout-sw600dp文件夹中的布局。
