【中文标题】图像反转：Android【英文标题】：Image getting reversed : Android 【发布时间】：2013-12-30 14:30:18 【问题描述】：我尝试使用表面视图捕获图像并将其保存在文件夹中。现在，当我在 imageview 中查看图像时，显示的图像是相反的。我怎样才能看到图像而不被反转。任何建议请............
这是代码的一部分..

见***.com/a/20480741/2556111 【参考方案1】：试试这个代码，希望对你有帮助。
int rotate = 0;
try
getContentResolver().notifyChange(imageUri, null);
File imageFile = new File(imagePath);
ExifInterface exif = new ExifInterface(
imageFile.getAbsolutePath());
int orientation = exif.getAttributeInt(
ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_NORMAL);
switch (orientation)
case ExifInterface.ORIENTATION_ROTATE_270:
rotate = 270;
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotate = 180;
break;
case ExifInterface.ORIENTATION_ROTATE_90:
rotate = 90;
break;
Log.v("***TAG***", "Exif orientation: " + orientation);
catch (Exception e)
e.printStackTrace();
【讨论】：
我已经编辑了代码......我添加了这个代码......bt它不起作用......你能验证代码吗 在onPictureTaken方法中，捕获图像后保存图像 Common.TAG 只是一个字符串 当我添加这一行 Log.v(Common.TAG, "Exiforientation:" +orientation);共同未解决.... 我告诉过你它是一个字符串，你可以在这里放任何字符串，就像我更新我的解决方案一样。以上是关于图像反转：Android的主要内容，如果未能解决你的问题，请参考以下文章
