如何在Xamarin.Forms中显示设备存储中的图像？

Question

I need to set the Source property of an image to the path returned after the user has picked it from gallery or camera (using Plugin.Media) the path looks like this:

/storage/emulated/0/Android/data/com.company.myApp/files/Pictures/temp/Screenshot_20181225-134128_6.jpg

I tried this

ImageSource.FromUri(new Uri(file.FilePath, UriKind.RelativeOrAbsolute));

but the image doesn't show anything,

Answer 1

you can create an object of MediaFile like,

public MediaFile AttachedImage;

and store captured image into it so that your below issue will resolved, this exception is thrown: System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Stream has been closed . you can get Image Stream any time from that object like,

img.Source = AttachedImage.GetStream().

it will sure resolve your issue.

Answer 2

Media Plugin returns a file with the path. You have to use this, for the file:

image.Source = ImageSource.FromStream(() =>
    {
        var stream = file.GetStream();
        return stream;
    });
