拍摄照片的代码挂在takePicture上。该代码适用于运行Android 2.2或4.0的设备。它运行在运行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，但发现这很奇怪，因为系统相机应用程序工作。这是我在执行takePicture方法时记录的LogCat条目。是否有人能够发现可能会提示的内容？

试试这个..
如果您的相机挂在拍照上，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();
}
}
});
//否则你可能会这样做..

mCamera.setParameters(p);
try {

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

mPreviewRunning = true;
}

事实证明，在Android 2.3中，您需要创建一个SurfaceView并使用StartPreview来拍摄照片。 Android文档显示了如何创建此SurfaceView，但它也表示您不需要“活动”来拍摄照片，并且它们的示例仅显示从活动中拍摄的照片。
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文档存在不一致之处。一方面，他们告诉你，你不需要预览（对于Android 2.2和4.0来说似乎都是如此），但你显然需要2.3。
