今天在做图片合成时,首先从相册中选择图片,然后判断该图片是否旋转了,今天就讲下图片是否旋转,直接上代码

/**
	 * 读取照片exif信息中的旋转角度
	 * 
	 * @param path
	 *            照片路径
	 * @return角度  获取从相册中选中图片的角度
	 */
	public static int readPictureDegree(String path) {
		if (TextUtils.isEmpty(path)) {
			return 0;
		}
		int degree = 0;
		try {
			ExifInterface exifInterface = new ExifInterface(path);
			int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
			switch (orientation) {
			case ExifInterface.ORIENTATION_ROTATE_90:
				degree = 90;
				break;
			case ExifInterface.ORIENTATION_ROTATE_180:
				degree = 180;
				break;
			case ExifInterface.ORIENTATION_ROTATE_270:
				degree = 270;
				break;
			}
		} catch (Exception e) {
		}
		return degree;
	}
