重定向/复制用户界面外部输出 [英] Redirecting/duplicating the UI to an external output
问题描述
是否有可能在Android框架来复制所显示的主显示（UI）？
Is it possible in the Android framework to duplicate what is displayed on the main display (UI)?
我有一个情况我需要证明我的应用程序很多人来说，这将是比较容易做，如果我可以复制屏幕内容到外部显示器/电视。我没有结婚使用 HDMI 端口的想法，我会很乐意通过Wi这样做-Fi或蓝牙或 USB 如果需要的话。我所寻找的是看我可以做类似于Windows不会在默认情况下，当第二台显示器连接的东西。
I have a situation where I need to demonstrate my app to many people, and it would be easier to do if I can duplicate the screen contents to an external monitor/TV. I am not married to the idea of using the HDMI port, I would be happy doing this through Wi-Fi or Bluetooth or USB if need be. What I am looking for is to see if I can do something similar to what Windows does by default when a second monitor is connected.
我公司已通过开发商的文档和一直没能找到任何可以让我做这件事，但它不会是第一次，我错过了一些东西。具体来说，我需要与宏达电Evo 做到这一点。
I have been through the developer's documentation and haven't been able to find anything that would allow me to do this, but it would not be the first time I've missed something. Specifically I need to do this with an HTC Evo.
推荐答案
您的选择是有限的，主要是由你选择的设备。而HTC EVO的HDMI端口将只播放，通过内置的Gallery应用程序的应用程序（视频和静态照片）。
Your options are limited, mostly by your choice of device. The HTC EVO's HDMI port will only play back apps via the built-in Gallery application (videos and still photos).
您将需要使用软件投影机如的Droid @屏幕 - - 附上您的EVO到连接到投影机的Android SDK-配备笔记本电脑。 Droid的@屏幕上会显示EVO屏幕上的笔记本电脑（和，从那里，投影机）。然而，帧速率被限制在约5-6帧，由于在SDK工具德罗伊德@屏幕利用限制。
You will need to use a "software projector" like Droid@Screen -- attach your EVO to a Android SDK-equipped notebook that is connected to a projector. Droid@Screen will display the EVO's screen on the notebook (and, from there, on the projector). However, the frame rate is limited to about 5-6 fps, due to limitations in the SDK tools that Droid@Screen leverages.
或者，让您的双手在宏达电Droid Incredible，它支持通过一个特殊的电缆复合输出到主屏幕上什么电视。三星Galaxy Tab还支持本作什么，不涉及 SurfaceView ，根据我的实验日期。在三星Galaxy S的某些版本也支持这一点，至少在一定程度上。
Or, get your hands on an HTC Droid Incredible, which supports composite output to TVs of anything on the main display via a special cable. The Samsung Galaxy Tab also supports this for anything that does not involve a SurfaceView, based on my experimentation to date. Some versions of the Samsung Galaxy S also support this, at least to some extent.
或者，使用网络摄像头。
Or, use a webcam.
或者，使用ELMO（基本上是专为文件或设备投影摄像头）。
Or, use an ELMO (basically a webcam designed for document or device projection).
