我的拍照代码挂在 takePicture 上。该代码在运行 Android 2.2 或 4.0 的设备上运行良好。它不能在运行 2.3 的华为上运行。目前我不确定是设备还是 API。我怀疑该设备，但发现这很奇怪，因为系统相机应用程序可以正常工作。这是我在执行 takePicture 方法时记录的 LogCat 条目。有没有人能够在其中发现一些可能给出提示的东西？

事实证明，在 Android 2.3 中，您需要创建一个 SurfaceView 并使用 StartPreview 才能拍摄照片。Android 文档显示了如何创建此 SurfaceView，但它还说您不需要 Activity 来拍照，他们的示例仅显示从 Activity 中拍摄的图片。

我使用他们的示例代码创建了 SurfaceView，但不必将其应用于 FragmentLayout。

我个人认为 Android 文档中存在不一致之处。一方面，他们告诉您不需要预览（Android 2.2 和 4.0 似乎是这样），但您显然需要 2.3。

尝试这个..

如果您的相机在拍照时挂起，您可以试试这个..

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();
            }
        }
    });

//否则你可能会去这个..
