为什么Camera.setParameters（Camera.Parameters）不会对索尼爱立信X10与Droid的工作？ [英] Why Camera.setParameters(Camera.Parameters) does not work on Sony-Ericsson X10 and Droid?

问题描述

有没有人遇到一个奇怪的行为与相机API的索尼爱立信X10或Droid的使用时？

Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid?

例如下面的code不会对这些设备的工作。结果我得到了很多对市场的翻译负反馈到很多订单取消...

For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders...

mParameters.set("rotation", orientation);
mParameters.set("jpeg-quality", img_quality);
mParameters.set("picture-size", "1024x768");
mCamera.setParameters(mParameters);

您可以建议获得相同的另一种方式？谢谢你。

Could you suggest an alternative way of achieving the same? Thanks.

推荐答案

您不能随便设置随机值的相机参数，因为你不知道，如果硬件是要支持，所以你需要先问！

You can't just set random values in the camera parameters because you don't know if the hardware is going to support that, so you need to ask first!

mCamera = Camera.open();
Camera.Parameters params = mCamera.getParameters();
List<Size> sizes = params.getSupportedPictureSizes();
// See which sizes the camera supports and choose one of those
mSize = sizes.get(0);
params.setPictureSize(mSize.width, mSize.height);
mCamera.setParameters(params);
