Android - 让相机照片方向无效

时间：2014-03-14 02:15:44

标签： android-intent camera orientation photo

当我尝试拍摄照片时（相机意图之后）我得到了一些异常，它强制关闭我的应用程序。它发生了一些时间，所以我不知道原因是什么。需要帮助!!! 

public int getCameraPhotoOrientation(){
    BitmapFactory.Options bounds = new BitmapFactory.Options();
    bounds.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(mCurrentPhotoPath, bounds);

    ExifInterface exif;
    int rotationAngle = 0;

    try {
    exif = new ExifInterface(mCurrentPhotoPath);
        String orientString = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
        int orientation = orientString != null ? Integer.parseInt(orientString) :     ExifInterface.ORIENTATION_NORMAL;
        if (orientation == ExifInterface.ORIENTATION_ROTATE_90) rotationAngle = 90;
        if (orientation == ExifInterface.ORIENTATION_ROTATE_180) rotationAngle = 180;
        if (orientation == ExifInterface.ORIENTATION_ROTATE_270) rotationAngle = 270;
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    return rotationAngle;
}

答案 0 :(得分：0)

显然，new ExifInterface(mCurrentPhotoPath)失败了。如果文件名已损坏，可能会发生这种情况，因此首先要检查的是打印logcat的路径并确保其健康。也许，该文件已损坏。也许，具体设备不支持Exif。如果您想要更具体的答案，请提供更多详细信息有时会发生。

祝你好运。
