在Windows Phone中更改其来源时图像未出现

Question

When I want to change an image's source, the image simply disappears.

The code I'm using:

tactImg.Source=tactImgList[i];

tactImgList = new BitmapImage[32];
tactImgList[0] = new BitmapImage(new Uri("ms-appx:///Assets/Images/1.png", UriKind.Absolute));

What am I doing wrong? Is there something I need to add to an xaml file or I'm making the global array wrong?

Answer 1

You don't need to use ms-appx in Windows Phone 8 projects , it's for WinRT projects.

Make sure your image's Build type is Content , remove the ms-appx part and since your image has relative uri , set your UriKind to Relative.

Answer 2

First, fill in the data, and then change the source. tactImgList = new BitmapImage[32]; tactImgList[0] = new BitmapImage(new Uri("ms-appx:///Assets/Images/1.png", UriKind.Absolute)); tactImg.Source=tactImgList[i];

Or use ObservableCollection for storing images.
