推荐答案

我一直在拉我的头发了这一点，我想我找到了问题，至少是关于我的应用程序 - 它有什么做的的preVIEW图像相对于所捕获的图像的高宽比。

I've been pulling my hair out over this and I think I found the issue, at least with regards to my app - it's got something to do with the aspect ratio of the preview image versus the captured image.

在我的情况，我的code的嗅出根据屏幕的高宽比理想的preVIEW大小。 S4的是一个1080的电话，所以preVIEW形象是1920×1080，这是一款16：9的纵横比。但我的code是很难coded到捕捉1600×1200的图像，这是4：3，因为这是我所需要的。但1600x1200的不是有效的尺寸S4支持之一

In my case, my code was sniffing out the ideal preview size based on the aspect ratio of the screen. The S4 is a 1080p phone, so the preview image was 1920x1080, which is a 16:9 aspect ratio. But my code was hardcoded to capturing a 1600x1200 image, which is 4:3, because that's all I needed. But 1600x1200 is not one of the valid sizes the S4 supports.

如果不设置的大小，S4捕获4128x3096，这是最大的尺寸，并且为4：3，但线条仍出现了。有一次，我告诉相机捕捉到了16：9的照片，该行就走开了。在你的情况，你可能需要调整preVIEW的纵横比。

Without setting the size, the S4 captured 4128x3096, which is the maximum size, and is 4:3, but the lines still appeared. Once I told the camera to capture a 16:9 photo, the lines went away. In your case, you might want to adjust the preview's aspect ratio.

下面是一些code，可以告诉你可用的尺寸。

Here's some code which can tell you the available sizes.

    List<Camera.Size> previewSizes = p.getSupportedPreviewSizes();

    int i = 1;

    for (Size previewSize : previewSizes) {
        Log.v("DebugCamera", "previewSize " + i++ + " width: " + previewSize.width + " height: " + previewSize.height);
    }

    List<Camera.Size> pictureSizes = p.getSupportedPictureSizes();

    i = 1;

    for (Size pictureSize : pictureSizes) {
        Log.v("DebugCamera", "pictureSize " + i++ + " width: " + pictureSize.width + " height: " + pictureSize.height);
    }
