Android：相机不会拍照

Question

拍摄照片的代码会挂在takePicture上。该代码可以在运行Android 2.2或4.0的设备上正常工作。它不运行在我运行2.3的华为上。目前我不确定它是设备还是API。我怀疑该设备，但自系统相机应用程序工作以来发现这种奇怪。这是我在执行takePicture方法时记录的LogCat条目。有人能够发现一些可能给出提示的东西吗？

Answer 1

试试这个..

如果您的相机拍照挂起，你可以尝试这个..

camera.setPreviewCallback(new PreviewCallback() { 

     @Override 
     public synchronized void onPreviewFrame(byte[] data, Camera arg1) { 
      if (!mTakePicture) { 
       CameraPreview.this.invalidate(); 
      } else { 

       if (mTakePictureCallback != null && !mPictureTaken) { 
        int rgb[] = new int[previewSize.width*previewSize.height]; 
        decodeYUV420SP(rgb, data, previewSize.width, previewSize.height); 
        Bitmap memoryImage = Bitmap.createBitmap(rgb, previewSize.width, previewSize.height, Bitmap.Config.ARGB_8888); 
        ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
        memoryImage.compress(CompressFormat.JPEG, 100, baos); 
        shutterSound(); 
        setBackgroundDrawable(new BitmapDrawable(getContext().getResources(), memoryImage)); 
        mTakePictureCallback.onPictureTaken(baos.toByteArray(), arg1); 
       } 
       mPictureTaken = true; 
       camera.stopPreview(); 
      } 
     } 
    }); 

//否则你可能会去的..

    }

     mCamera.setParameters(p); 
     try { 
      mCamera.setPreviewDisplay(holder); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     mCamera.startPreview(); 
     mPreviewRunning = true; 
    }

Answer 2

原来，在Android 2.3的，你需要创建一个SurfaceView并使用StartPreview为了将拍摄的照片。 Android文档展示了如何创建这个SurfaceView，但它也表示你不需要一个活动来拍照，他们的例子只显示一个活动中拍摄的照片。

我用他们的示例代码来创建SurfaceView，但不必将其应用于FragmentLayout。

我个人认为Android文档存在不一致。一方面，他们告诉你，你不需要预览（这对于Android 2.2和4.0来说似乎是正确的），但你显然需要2.3。
