拍照不SurfaceView或没有照片意向活动 [英] Taking picture without SurfaceView or without Photo Intent Activity

问题描述

我需要从手机拍照的照片来分析它，但我并不需要出示SurfaceView内容（摄像机的图像）。我可以使用Camera类没有SurfaceView持有人？一种方法是简单地隐藏SurfaceView但是，有没有办法不使用它呢？

我想这样的，但它抛出一个错误：takePicture失败。

的onCreate：

  mCamera = getCameraInstance（）; //私人相机mCamera;
mCamera.start preVIEW（）;button.setOnClickListener（新OnClickListener（）{
   @覆盖
   公共无效的onClick（视图v）{      mCamera.takePicture（NULL，NULL，mPicture）;   }
}）;
 

相机：

 公共静态相机getCameraInstance（）{
            相机C = NULL;
            尝试{
                C = Camera.open（）; //试图得到一个摄像头实例
            }赶上（例外五）{
                e.printStackTrace（）;
            }
            返回℃; //如果相机不可用，则返回null
        }    私人Camera.PictureCallback mPicture =新Camera.PictureCallback（）{        @覆盖
        公共无效onPictureTaken（字节[]数据，相机摄像头）{            的System.out.println（点击）;
        }
    };
 

解决方案

我解决这么surficeView没有看到在SurficeView思想促进新视图我的问题。我通过搜索其他的解决办法，但都没有成功花费相当的时间。

I need to take a photo from phone camera to analyze it, but I do not need to show the content (image of camera) on SurfaceView. Can I use Camera class without SurfaceView holder? One way is to simply hide SurfaceView but Is there a way to not using it at all?

I tried like this but it throws an error: takePicture failed

onCreate:

mCamera = getCameraInstance();   //private Camera mCamera;  
mCamera.startPreview();

button.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {

      mCamera.takePicture(null, null, mPicture);

   }
});

Camera:

public static Camera getCameraInstance() {
            Camera c = null;
            try {
                c = Camera.open(); // attempt to get a Camera instance
            } catch (Exception e) {
                e.printStackTrace();
            }
            return c; // returns null if camera is unavailable
        }

    private Camera.PictureCallback mPicture = new Camera.PictureCallback() {

        @Override
        public void onPictureTaken(byte[] data, Camera camera) {

            System.out.println("CLICK");
        }
    };

解决方案

I solve my problem by puting new view over the SurficeView so surficeView was not seen. I spend quite a time by searching for other solution but without success.
