如何获取cameraID并使用setTorchMode? [英] How does one retrieve the cameraID and use setTorchMode?

问题描述

因此，Android M最近问世了，它现在具有称为setTorchMode的内置摄像功能.我很好奇这是如何作为参数工作的(字符串cameraID，布尔值true/false).布尔值显然指示了灯光是打开还是关闭，但是如何获取cameraID?我知道有一个名为getCameraIDList的方法，但是它返回一个ID数组，而不仅仅是一个ID数组.您怎么知道要使用该列表中的哪一个?

So Android M recently came out and it now has a built in cameralight function called setTorchMode. I was curious as to how this worked as the parameters are (String cameraID, Boolean true/false). The Boolean obviously dictates whether the light is on or off, but how do you get the cameraID? I know there's a method called getCameraIDList, but that returns an array of IDs, not just one. How do you know which one in that list to use?

推荐答案

您应该使用CameraManager的"getCameraIdList"函数，该函数将为您检索一个字符串列表，每个字符串代表一个活动的摄像机.

You should use CameraManager "getCameraIdList" function which will retrieve you a list of strings where each represent an active camera.
