如何检测，其中前置摄像头放置在设备？ [英] How to detect where front-facing camera placed on device?

问题描述

有没有来检测前置摄像头放置的Andr​​oid设备上的任何方式？

Is there any ways to detect where front-facing camera placed on Android device?

我觉得在手机上它总是在它的上面，耳机附近。但所有的片剂都不同。我查了华硕变压器和前置摄像头的侧面（在上面，如果我在横向模式下持有它），但是三星Galaxy Tab（第一代的Andr​​oid 2.2）的相机在它上面，像所有的手机。

I think on cell phones it's always on top of it, near the headphone. But all tablets are different. I checked Asus Transformer, and front camera is on the side (on top if I hold it in landscape mode), but Samsung Galaxy Tab (first gen, Android 2.2) has camera on top of it, like all cell phones.

那么，有没有办法来检查，其中前置摄像头放在哪里？也许我可以用code做，也许有对设备的规则？如Android 2.x设备都有它的顶部和Android 3.x设备对端？那么关于Adnroid内4.x的设备？

So is there way to check where front camera placed? Maybe I can do it with code, maybe there is a rule for devices? Like Android 2.x devices has it on top, and Android 3.x devices has on the side? Then what about Adnroid 4.x devices?

推荐答案

有没有办法做到这一点。阅读的http://developer.android.com/reference/android/hardware/Camera.CameraInfo.html

There is no way to do this. Read http://developer.android.com/reference/android/hardware/Camera.CameraInfo.html

有两个常量，您可以检查：

There are two constants you can check:

int CAMERA_FACING_BACK The facing of the camera is opposite to that of the screen.
int CAMERA_FACING_FRONT The facing of the camera is the same as that of the screen.

所以，我很抱歉 - 来检查它是否在一旁没办法

So I'm sorry - no way to check if it's at the side.
