Question

我一直在搜索这个网站的答案，但我找不到一个。我的Android应用程序不是在我的模拟器中从纵向交换到横向它只是显示侧面纵向屏幕。我已经创建了一个带有匹配的xml名称的layout和layout-land文件夹，依此类推。但它似乎没有采用布局版本。我没有onConfig（）函数或任何其他所以我想知道是否有人可以帮助???

mainpage.xml layout-land

Answer 1

这是一个模拟器错误，当您尝试以横向模式启动活动时，您将看到它将从layout-land加载mainpage.xml，

机器人：screenOrientation =＆＃34;景观＆＃34;

但是ctrl + f12不起作用，这是一个错误
