Android：锁定背景图片但旋转前景视图

Question

I have a Landscape background image in place. How do I lock it into position, but allow forground views to be rotated, eg a Dialog.

At the moment, either I lock the orientation so the dialog doesn't rotate, or I don't lock it and the background becomes tiny as I rotate the screen and it fills the narrow width of the screen.

Answer 1

I think your best bet would be to allow the rotation and just display a different background (the original background rotated 90 degrees)

You can catch the rotation in onConfigurationChanged, once you've added android:configChanges="orientation" to your activity in the manifest
