将元素方向从纵向更改为横向模式

Question

我希望在设备处于纵向模式时有两个垂直方向的按钮，在横向时有水平方向。如何只使用.xml文件获取它？我可以使用类似“styles.xml”和如果我有肖像这样做，如果我有风景做另一个吗？谢谢

Answer 1

The layouts in /res/layout are applied to both portrait and landscape.

To use a different layout in landscape, create a folder /res/layout-land and create another xml file here with the same name. Android will automatically choose the layout corresponding to the current screen orientation.

EDIT :

If you cannot create a second folder or are concerned about performances, then you can override the onConfigurationChanged() method, as explained here .
