最近做了关于二维码解析的模块

选用的是google的开源工程Zxing

 

在Zxing 添加闪光灯功能 如下:

在 com.xxx.xxx.Zxing.camera 包下的CameraManager类中

添加代码:

//openLight 是开启闪光灯

//offLight  是关闭闪光灯

  
  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);
    	  }
}


在你需要调用闪光灯的类中

			//开闪光灯
			CameraManager.get().openLight();

			// 关闪光灯
			CameraManager.get().offLight();


闪光灯的功能就加进来了

希望对大家有用
