android 照相机 人像,Android zxing – 人像相机预览/ surfaceview被拉伸/翘曲

我已经设法使用这里的答案将相机预览旋转为纵向：

然而，预览本身是拉伸/扭曲的 – 高度似乎正在拉伸以填充框(但是可能是宽度对于屏幕来说太大，并且正在被挤压以适合)

有没有办法“包装”内容，而不是让它伸展到适合表面视图？

编辑：我通过改变’CameraConfigurationManager’中的’findBestPreviewSizeValue’方法进行排序，并反转X和Y点(感谢下面的指针的sean owen！)，这里是代码：

private static Point findBestPreviewSizeValue(CharSequence previewSizeValueString,

Point screenResolution) {

int bestX = 0;

int bestY = 0;

int diff = Integer.MAX_VALUE;

for (String previewSize : COMMA_PATTERN.split(previewSizeValueString)) {

previewSize = previewSize.trim();

int dimPosition = previewSize.indexOf('x');

if (dimPosition < 0) {

Log.w(TAG, "Bad preview-size: " + previewSize);

continue;

}

int newX;

int newY;

try {

newY = Integer.parseInt(previewSize.substring(0, dimPosition));

newX = Integer.parseInt(previewSize.substring(dimPosition + 1));

//original:

//newX = Integer.parseInt(previewSize.substring(0, dimPosition));

//newY = Integer.parseInt(previewSize.substring(dimPosition + 1));

} catch (NumberFormatException nfe) {

Log.w(TAG, "Bad preview-size: " + previewSize);

continue;

}

int newDiff = Math.abs(newX - screenResolution.x) + Math.abs(newY - screenResolution.y);

if (newDiff == 0) {

bestX = newY;

bestY = newX;

//original:

//bestX = newX;

//bestY = newY;

break;

} else if (newDiff < diff) {

bestX = newY;

bestY = newX;

//original:

//bestX = newX;

//bestY = newY;

diff = newDiff;

}

}

if (bestX > 0 && bestY > 0) {

return new Point(bestX, bestY);

}

return null;

}
