相机FLASH_MODE_ON不工作的极限摩托 [英] Camera FLASH_MODE_ON not working on Moto X
问题描述
我有一个按钮，切换 FLASH_MODE_ON / FLASH_MODE_OFF 之间的闪光模式。切换适用于大多数的手机（我已经在Nexus 5的测试，S4和放大器; S3）？但它没有拍照时的Moto X.任何想法可能是什么这个原因闪烁
//设置相机PARAMS
最后Camera.Parameters PARAMS = mCamera.getParameters（）;
最终布尔shouldFlashBeOn =（Camera.Parameters.FLASH_MODE_ON.equals（params.getFlashMode（）））！;
params.setFlashMode（shouldFlashBeOn
？ Camera.Parameters.FLASH_MODE_ON
：Camera.Parameters.FLASH_MODE_OFF）; mCamera.setParameters（PARAMS）;
mCamera.start preVIEW（）; //设置状态的ImageButton
mImageButtonFlash.setSelected（shouldFlashBeOn）;
如果我遇到这种情况，我会先检查所有参数。然后找到我可以用什么样的价值观。例如，下面的打印所有的参数code
参数参数= mCamera.getParameters（）;
Log.i（照相机，param.flatten（）的toString（））;
然后检查日志

然后设置由code值之一
param.set（上，闪光模式）;
mCamera.setParameters（参数）;您可以试试。
I have a button that toggles the flash mode between
FLASH_MODE_ON/FLASH_MODE_OFF. The toggle works on most phones (I've tested on Nexus 5, S4 & S3) but it fails to flash when taking a picture on Moto X. Any ideas what could be the cause of this?// Set camera params final Camera.Parameters params = mCamera.getParameters(); final boolean shouldFlashBeOn = !(Camera.Parameters.FLASH_MODE_ON.equals(params.getFlashMode())); params.setFlashMode(shouldFlashBeOn ? Camera.Parameters.FLASH_MODE_ON : Camera.Parameters.FLASH_MODE_OFF); mCamera.setParameters(params); mCamera.startPreview(); // Set ImageButton state mImageButtonFlash.setSelected(shouldFlashBeOn);
解决方案If I meet this case, I'll check all parameters first. Then find what values I can use. For example, print all parameters by following code
Parameters param = mCamera.getParameters(); Log.i("camera", param.flatten().toString());Then check the log

You can see the values you can use
flash-mode-values=auto,off,on,torch;
Then set the one of the value by the code
param.set("flash-mode", "on"); mCamera.setParameters(param);You can have a try.
