，可以设置一个活动的方向在清单文件

但它也可以从code做呢？如果是的话，怎么办？

谢谢！

  setRequestedOrientation（ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE）;
 

it is possible to set the orientation of an activity in the manifest file.

but is it also possible to do it from code? if so, how?

thanks!

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
