LED &相机始终开启 [英] LED & Camera always ON
问题描述
我正在尝试打开设备摄像头并立即激活该设备 (android/iOS) 的 LED 灯.
I'm trying to open the device camera an activate immediately the LED light of that device (android/iOS).
我已经尝试了 appcelerator ti.media 事件，但没有奏效，这个模块也没有:Ti.光.
I've tried the appcelerator ti.media events but didn't work, neither this module: Ti.Light.
在这个链接上找到这个 activate-iphone-4-led-光

大家好！
对于 flash 的东西，你必须检查属性:Ti.Media.cameraFlashMode(区分大小写)
For the flash stuff you have to check the property: Ti.Media.cameraFlashMode (case sensitive)
你可以使用 Ti.Media.setCameraFlashMode(PARAM) 来改变它.
To change it you can use Ti.Media.setCameraFlashMode(PARAM) .
PARAM 可以是:Ti.Media.CAMERA_FLASH_OFF、Ti.Media.CAMERA_FLASH_ON、Ti.Media.CAMERA_FLASH_AUTO
PARAM could be: Ti.Media.CAMERA_FLASH_OFF , Ti.Media.CAMERA_FLASH_ON, Ti.Media.CAMERA_FLASH_AUTO
不幸的是你不能启动led并将其用作手电筒，你可以仅在拍摄时控制相机闪光灯处理(开、关、自动)照片.
Unfortunately you can’t start the led and use it as a torch, you can only control the camera flash handling (on, off, auto) while taking a photo.
有什么模块可以一直使用led灯?我只是在相机打开时需要这个.
There is any module that allow to use the led light all the time? I just need this while the camera is opened.
更新 1#:
我正在尝试使用具有嵌入相机和闪光灯方法的 ts.camera 小部件:
I’m trying to use your ts.camera widget, that have the embed camera and flash methods:
但是pw.custom.androidcamera"模块中没有方法switchFlashlight()，这个widget能用吗?
But there is no method switchFlashlight() in "pw.custom.androidcamera" module, this widget works?
更新 2#:
为了找到解决办法，我添加了这个手电筒模块，我试图在展示相机之前或之后调用它，但我认为不可能同时进行 2 个相机活动.
In order to find a workaroud, I've added this flashlight module, and I'm trying to call it before or after showing the camera, but I think that it's not possible to have 2 camera activities at the same time.
这是我的 index.js 文件:
This is my index.js file:
if(OS_ANDROID) {
flash = require('dk.napp.flashlight');
if(!flash.isFlashLightOn()) flash.turnFlashLightOn();
camera = require('pw.custom.androidcamera');
view = camera.createCameraView();
}
我收到此错误:
[DEBUG] : CameraViewProxy: Camera not available
[ERROR] : CameraViewProxy: Camera is null. Make sure
[ERROR] : CameraViewProxy: <uses-permission android:name="android.permission.CAMERA" />
[ERROR] : CameraViewProxy: is in you tiapp.xml file.
这是我的 tiapp.xml 文件:
This is my tiapp.xml file:
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.FLASHLIGHT"/>
<uses-feature android:name="android.hardware"/>
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera2"/>
<uses-feature android:name="android.hardware.camera2.params"/>
<uses-feature android:name="android.hardware.camera.flash"/>
<uses-feature android:name="android.hardware.camera.autofocus"/>
推荐答案
这两个模块可能会完成这项工作:
These two modules might do the job:
虽然很可能激活设备相机会覆盖对闪光灯的控制.
Although it could well be that activating the device camera will override the control over the flash light.
