Add flashlight for Android Zxing

Source: Internet
Author: User

I recently developed a QR code parsing module.

Google's open-source project Zxing

The Flash function added to Zxing is as follows:

In the CameraManager class under the com. xxx. xxx. Zxing. camera package

Add code:

// OpenLight enables the flashlight.

// OffLight is to turn off the flashlight

Public void openLight () {if (camera! = Null) {parameter = camera. getParameters (); parameter. setFlashMode (Parameters. FLASH_MODE_TORCH); camera. setParameters (parameter) ;}} public void offLight () {if (camera! = Null) {parameter = camera. getParameters (); parameter. setFlashMode (Parameters. FLASH_MODE_OFF); camera. setParameters (parameter );}}


In the class where you need to call the flashlight

// Turn on the flashlight CameraManager. get (). openLight (); // turn off the flashlight CameraManager. get (). offLight ();


The Flash function is added.

Hope to be useful to everyone
