我正在拍摄照片并将其存储到SD卡中,然后将其从SD卡中查看到ImageView中,但获得轮换…

我在纵向模式下捕获它,但在横向模式下获得结果图像…

有什么我想念的吗？

在这里找到ExifUtil.java课程

/**
 * Displaying captured image/video on the screen
 * */
private void previewMedia(boolean isImage) {
    // Checking whether captured media is image or video
    if (isImage) {
        imgPreview.setVisibility(View.VISIBLE);

        final Bitmap bitmap = BitmapFactory.decodeFile(filePath);
        Bitmap orientedBitmap = ExifUtil.rotateBitmap(filePath, bitmap);

        imgPreview.setImageBitmap(orientedBitmap);
    } else {
        imgPreview.setVisibility(View.GONE);
    }
}

但仍然在ImageView中显示旋转的图像…

解决方法:

您需要使用带有ORIENTATION_UNDEFINED的EXIF来获得正确的方向.

ExifInterface exif = null;
try {
    exif = new ExifInterface(path);
} catch (IOException e) {
    e.printStackTrace();
}  
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 
                                       ExifInterface.ORIENTATION_UNDEFINED);

并旋转位图：

Bitmap bmRotated = rotateBitmap(bitmap, orientation);
