推荐答案

如果你得到一个空白的屏幕可能是因为你的活动是创下了新的内容查看，但一直没有得到妥善处理。是否曾经完全载入？如果这只是它是黑色的开头，然后渲染。试试在你的onCreate切换的结束设定内容查看。这将使它留在第一项活动，避免起至一切都加载切换视图。

If you're getting a blank screen it could be because your activity is setting a new contentview but it hasn't been processed properly. Does it ever load completely? If it's just that it's black at the beginning and then renders. Try setting the contentview at the end of your switching in onCreate. This will make it remain on the first activity and avoiding switching views on till everything is loaded.

至于你的第二个问题。从相机的实时视频输入？

With regards your second question. Is the live video feed from the Camera?

如果是，则设置在后台相机视图，做一个透明的LinearLayout（或任何你的布局）结束，然后把你的各种意见。

If it is, set the camera view in the background, make a transparent LinearLayout (or whatever your layout is) over it and then put your various views there.
